In 1998, the City developed an Updated Master Plan that has guided project development for the past 4 years. The City has completed construction of reclaimed water systems to serve the Clearwater Beach areas. Currently, the City is designing an expansion of service along Drew Street west of McMullen- Booth to serve areas adjacent to Drew Street, Old Coachman Road and Park Place Boulevard. This project will also expand service on Union Street between McMullen-Booth and U.S. 19. Funding approval has been received for design and construction of reclaimed water systems in the Harbor Oaks area of the City. Funding for reclaimed water projects is typically provided through revenues from the Water and Sewer Enterprise Funds, grant funding and from reclaimed water sales. Due to the extensive capital costs required to construct the infrastructure to provide reclaimed water service and the relatively low revenues generated from reclaimed water sales, outside funding has been a key component to the funding the necessary capital projects. Recent changes in funding eligibility requirements and issues related to the City's surface water discharges have prompted the City staff to request a review and update of the project prioritization. A significant portion of project funding for reclaimed water system development has historically been through grants from the Southwest Florida Water Management District (SWFWMD). The District's funding criteria has evolved in the last few years to rely heavily on a project's cost relative to the benefit received from offsetting the use of potable water and groundwater. Communities throughout the District are vying for limited funding and the project cost/benefit ratio is a key factor in project selection to receive funds. This re-visit of the Master Plan has included a review and update of project priority based on the Cost/Benefit ratio of the project. The intent of relying on the Cost/Benefit evaluation is to insure that the City of Clearwater's proposed reclaimed water project are cost competitive with other projects seeking limited grant funding. Without this funding source, the City's progress on reclaimed water system development will be significantly reduced. The table on the following page outlines the results of reprioritization of the projects to be implemented over the next 20 years.

The City's demand could exceed the available supply with full build-out of the reclaimed water system. Further, to maximize the full potential of 20 MGD storage during wet weather periods is required for as much as 1.1 billion galions of reciaimed water. • Based on projections, the City will exceed the daily demand for reclaimed water for periods of lowest supply availability as eariy as 2008. The City can continue distribution system expansion beyond 2008 with more restrictive ordinances for the use of reclaimed water. Other options for continued expansion of the system will require seasonal storage to meet the peak flows during the dry season with water stored during the wetter months. Above ground storage options of the magnitude necessary will be extremely costly, if not, wholly impractical. Aquifer Storage and Recovery provides a potential for developing large volumes of storage locally with minimal land impacts. The suitability of the geologic formations in this area need to be closely evaluated to insure the aquifer can support the needs for storage while protecting the sensitive water supply aquifer in which the City is investing for potable water supply. The City should proceed with the joint feasibility study with the Southwest Florida Water Management District to begin to understand the potential for this option. • The option of expediting construction of reclaimed water systems in order to eliminate the two surface water discharges was evaluated. The least cost alternative to meet this objective is to construct reclaimed water infrastructure with estimated costs of $102 million. The extensive capital requirements coupled with extensive permitting issues make this approach very difficult to implement in a short time frame. In addition, the City would not capitalize on the SWFWMD cooperative funding with a short-term capital requirement of this magnitude. • The City will need to continue expansion of above ground storage facilities and pumping facilities to support the operation of the reclaimed water system and the daily fluctuations in supply and demand. The City currently has no pumping capability from the East APCF for Review of Reclaimed Water Master P/an Update City of Clearwater 0992-0072 December 2001 Page 3 ' ' ' ' , ' ' � 1 ' , , ' ' ' 1 , ' ' utilization of East plant effiuent in the system. It is recommended that a minimum of one day's reciaimed water storage capacity should be provided. For the 20 year planning period this will require: � New reclaimed water pumping facility at the East APCF. New 7.5 MG storage and pump station near the Clearwater Air Park. ■ Additional 5.0 MG storage tank at the Northeast APCF. • The cost of interconnecting the City of Clearwater with the City of Largo is estimated to be $5.0 million. This interconnect could provide some operational flexibility, however, opportunities to transfer water from one system to the other is limited because typically both systems will have high demands or excess water at the same times. Neither community has addressed the seasonal storage issue which could afford some greater opportunity to shift flows during high demand periods, therefore, this interconnect is not considered a high priority at this time. • City staff presented the Draft Report to the City of Clearwater Commission on April 30, 2001. This Final Report incorporates the comments received during the Presentation. Appendix A contains details on these items. • The City staff conducted Public Meetings on August 6 and 7 to present the Draft Plan to the residents and to seek input for the Final Report. A recap of resident's comments are also included in Appendix A.

Beginning in 1998, the City initiated its first residential/commercial reclaimed water system by expanding from the Marshall Street Advanced Pollution Control Facility (APCF) to the Island Estates community. Prior to this time, the City provided reclaimed water to a few golf course areas and recreation spaces near two of the APCFs. The City is continuing the expansion of the system on Clearwater Beach, with plans following to service areas targeted in the 1998 Reclaimed Water Master Plan Update. From late 1999 and through early 2001, Clearwater and the Tampa Bay region experienced severe drought conditions. In response to the drought conditions, more stringent watering restrictions were implemented across the region, including the City of Clearwater. With the increasing burden placed on our water resources, the City desires to re-visit the 1998 Reclaimed Water Master Plan Update to evaluate the appropriateness of the plan given the ever-changing conditions and the need to continually maximize the effectiveness of the reclaimed water program. McKim & Creed, P.A. was contracted by the City of Clearwater to review the Reclaimed Water Master Plan Update (McKim & Creed, P.A., 1998) and provide a re-assessment of the reclaimed water service areas. Review of Reclaimed Water Master Plan Update City of C/earwater 0992-0072 December 2001 Page 5 ' ' , ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' 2.0 RECLAIMED WATER BACKGROUND The City began utilization of treated effluent in the 1980s with the completion of an effluent pumping station and low pressure transmission main at the Northeast APCF. This system serves the Countryside Golf Course and the Chi Chi Rodriquez Driving Range area. In 1990, the City began to explore a City-wide expansion of the reclaimed water system. The City's first Reclaimed Water Master Pan was prepared in 1990 by Camp Dresser and McKee, Inc. and included a three-phase, $70 million expansion program. Support for this program was not sufficient to make significant progress. It was not until 1998 that the system began to expand to serve residential customers by constructing the system that now serves the Island Estates area and other City parks and open spaces in the western portion of the City. The facilities to serve these areas include a new pumping facility and a storage system at the Marshall Street Advanced Pollution Control Facility. Due to the time that elapsed between completing the original master plan and beginning the expansion, and due to changes in the fundamental approach to developing the reclaimed water program that became evident with the expansion of the system to serve Island Estates, the City recognized the need to update the reclaimed water master plan to take into consideration the then current conditions and the re-direction of the system development. McKim & Creed, P.A, developed the Reclaimed Water Master Plan Update in 1998. This document has provided the guidance for expansion of six subsequent projects to extend reclaimed water service. These projects are in various stages of planning, design, construction or operation and are described in Section 4.0. Funding for reclaimed water projects is difficult from the standpoint that reclaimed water sales typically do not generate sufficient revenues to cover both operating costs and capital cost repayment. The City has been successful in attracting the support of the Southwest Florida Water Management District and the Pinellas-Anclote Basin Board for a portion of the funding of all previous reclaimed water projects beginning with the Island Estates Reclaimed Water Project in 1998. To date, the City has received commitments of over $9.5 million dollars from the Pinellas-Anclote Basin Board for reclaimed water projects totaling over $22 million in cost. The City has funded the remaining portion of the cost of these projects using revenues generated from the Water and Sewer Enterprise Funds and with a small portion from reclaimed water sales. The continued success of developing reclaimed water systems at a reasonable pace will be dependent on continued success in grant funding from SWFWMD to sustain. The scope of this project included an evaluation of the City's Master Plan to insure that projects are competing favorable for the limited grant funds available from the SWFWMD. The project Review of Reclaimed Water Master Plan Update City of C/earwater 0992-0072 December 2001 Page 6 , tCost/Benefit ratio of proposed projects detailed later in this report is a key factor in eligibility for funding. Therefore, this report focuses around projected Cost/Benefit ratios for comparing ' project priorities. This report will amend the 1998 Master Plan based on current conditions and based on a review of cost/benefit ratios. The report wiil also address specific issues the City ' Staff has requested to be further evaluated. The foilowing section provides a more detailed scope of this report.

Review the Reclaimed Water Master Plan Update (1998). B. Identify areas that have large numbers of private, residential irrigation well users by discussions with City staff and reviewing well construction records obtained from the SWFWMD. We may also contact homeowners groups through the association of homeowners. C. Obtain and review lawn meter usage and potable water usage from the City billing records for target areas. D. Evaluate the impact to the expanding reclaimed water pumping, storage and transmission system at the Northeast Advanced Pollution Control Facility (APCF) with proposed additional reclaimed water users in the Northeast Clearwater area. E. Develop projected irrigation rates and refined demands for reclaimed water for the identified areas. F. Review the most recent funding criteria changes by the Southwest Florida Water Management District (SWFWMD), primarily with respect to funding of distribution systems. Evaluate the impact of these changes on the priorities and costs for extending reclaimed water service to target areas identified and areas previously programmed in the Master plan. G. Define infrastructure requirements necessary to extend reclaimed water service to these target areas. Utilize hydraulic model as needed. H. Develop budgetary costs of expanding the reclaimed water system to these target areas. Review and prepare revisions and/or updates as appropriate to project costs for those areas in the Master Plan based on new information. I. Determine potable water and ground water offsets for the target reclaimed water service area(s). Prepare estimates of cost/benefit utilized by the SWFWMD to evaluate project viability for funding. Review of Reclaimed Water Master P/an Update City of C/earwater 0992-0072 December 2001 Page 8 ' ' , ' ' ' l J. ' , ' ' ' ' ' ' � ' ' , J. Review and refine existing prioritized lists of projects to reflect addition of the northeast Clearwater area and other areas that are identified for cost effective reclaimed water service. � K. Refine maps of the City to iilustrate and exhibit the proposed modification to the areas and/or priorities previously proposed. L. Assist the City in obtaining grant funding for newly defined reclaimed water project in northeast Clearwater area that may result from this study. M. Prepare brief draft report in the form of an amendment to the Master Plan Update for submittal to the City. Incorporate comments into a final report that will amend the previous Master Plan Update. N. Attend meetings with the City to review progress on the project and to review results of preliminary and final findings and recommendations. Assist in preparing presentations of findings as needed. Subsequent to the drafting of this scope, the City has determined a need to address other related factors that may affect the long-term development of the reclaimed water system. These issues include: ➢ More stringent limitation on discharge of treated effluent included in new NPDES permits and possible future permit limitations. ➢ Possible coordination with adjoining communities to improve system reliability. ➢ Consideration of elimination of effluent discharges to surface water. ➢ Coordination of SWFWMD planning efforts. We have incorporated these issues in the review and update of the Master Plan. The City will face several decisions in deciding on the most cost effective and most environmentally acceptable system configuration. This report intends to provide data, information and evaluations to facilitate these decisions.

The Marshall Street APCF currently produces ' a minimum of 6 MGD (million gallons per day) of treated effluent and a 3-month average of 7 MGD. Reclaimed water from the facility is utilized at the following areas: Clearwater Country Club, Philip Jones Field, Jack Russell Stadium, Coachman Park, Memorial Causeway median, ' Pier 60, Island Estates and Clearwater Beach. 1 ' ' ' ' ' ' ' The Northeast APCF currently produces a minimum of 5 MGD of treated effluent and a 3-month average of 6 MGD. Approximately 1 MGD of reclaimed water is utilized by the following facilities: Countryside Golf Course, Chi Chi Rodriquez Golf Course, Countryside Golf Driving Range, and Countryside Sports Complex. The East APCF produces treated wastewater to reclaimed water standards, but due to the lack of pumping and storage facilities at the plant, reclaimed water from the plant is currently not utilized in the City's reclaimed water system. Future reclaimed water plans for the East APCF include the addition of a pumping station at the plant and potentially an offsite storage facility. McKim & Creed reviewed the City's reclaimed water pumpage information to calculate reclaimed water irrigation rates for the areas currently using reclaimed water. Review of these areas is provided below and indicates that the reclaimed water irrigation rate is 1" per week on average and 1.5" per week during peak demand times, which equals a peaking factor of 1.5. 5.1 Island Estates, Philip Jones Field, Jack Russell Stadium, Coachman Park, Memorial Causeway, and Pier 60 Island Estates, Philip Jones Field, Jack Russell Stadium, Coachman Park, Memorial ' Causeway median, and Pier 60 have approximately 173 acres open to irrigation. Based on the City's records, these areas used an average of 474,100 gpd (gallons per day) � during 1999 once the entire Island Estates area was brought on line in March 1999. The majority of this water was used to irrigate the Island Estates community. Using the ' ' ' , following equation and an 80% connection factor for the Island Estates community, a reclaimed water irrigation rate of 0.9" per week is calculated: ➢ � In/week =(474,100 gpd/173 acres) *(7 days/wk)'` (ft^3/7.48 gal) *(acre/43560 ft^2) *(12"/ft) / .8 In/week = 0.9" per week Review of Reclaimed Water Master P/an Update City of C/earwater 0992-0072 December 2001 Page 93 ' � ' ' � � ' ' ' �J , , ' An 80% connection factor refiects the percentage of customers estimated to be connected to the reclaimed water system. During 1999, a peak reclaimed water usage of 705,600 gpd occurred in May, which equates to an irrigation rate of 1.3" per week. During drought conditions in May and June 2000, these areas had a demand of 798,000 gpd of reclaimed water, equating to 1.5" per week. 5.2 Clearwater Country Club Ciearwater Country Club has approximately 65 irrigable acres. Based on the City's records, Ciearwater Country Club used an average of 218,000 gpd during 1999, which calculates to an irrigation rate of 0.9" per week by using the following equation: IJ ➢ In/week =(218,000 gpd/ 65 acres) *(7 days/wk) *(ft^3/7.48 gal) *(acre/43560 ft^2) *(12"/ft) In/week = 0.9" per week During 1999, a peak reclaimed water usage of 340,000 gpd occurred in April, which equates to an irrigation rate of 1.3" per week. During drought conditions in May and June 2000, Clearwater Country Club used approximately 380,000 gpd of reclaimed water, equating to an irrigation rate of 1.5" per week. 5.3 Countryside Golf Course, Chi Chi Rodriquez Golf Course, Countryside Sports Complex, and Countryside Driving Range. The Countryside Golf Course, Chi Chi Rodriquez Golf Course, Countryside Sports Complex, and Countryside Driving Range have approximately 196 irrigable acres. In 1999, an average of 774,247 gpd of reclaimed water was used by these four areas, which calculates to an irrigation rate of 1.0" per week. The peak month during 1999 was May and 1,238,000 gpd of reclaimed water was utilized during that month, equating to ' an irrigation rate of 1.6" per week. During drought conditions in May and June 2000, these areas demanded approximately 1,461,000 gpd, which equals an irrigation rate of ' ' ' ' ' 1.9" per week.

These areas were defined by land use, size, major roadway boundaries and other related features. Reclaimed water demand for each service area was determined by projecting the amount of land open to irrigation, or irrigable space. Irrigable tspace acreage per service area was determined in the Reclaimed Water Master Plan Update (1998) and those acreage values were utilized in this report. As a comparison, irrigable acreage ' information was obtained from the City of Clearwater and Pinellas County GIS (Geographic ' ' ' ' ' , ' ' ' ' ' ' , Information Systems) Departments. Their acreage information compared favorably to the irrigable acreage determined in the 1998 Reclaimed Water Master Plan Update. Based on the review of the existing reclaimed water demand as discussed in Section 5.0, an average reclaimed water demand of 1" per week was utilized to estimate the reclaimed water demand of the City's 25 reclaimed water service areas. These reclaimed water service areas and the projected demand are shown in Table 6-1 on the following page. Each area has a"% Connected" factor which relates to the projected number of connections relative to the total potential customer base. For example, areas that have more commercial or industrial land use have a lower "% Connected" factor since it is projected that fewer of these customers will connect to the reclaimed water system. The "Other RCW Demand" category accounts for properties within the reclaimed water service area such as parks, cemeteries, landscaped medians, golf courses, and schools projected to utilize reclaimed water. The "Total RCW Demand" is the sum of the "Irrigable Acreage RCW Demand" and the "Other RCW Demand".

It is assumed that the influent wastewater flow to each treatment facility is equal to the treated wastewater flow (i.e. reclaimed water). The historical influent wastewater flows to the Marshall Street, Northeast, and East APCFs are shown in Figures 7-1, 7-2, and 7-3, respectively. The combined flow of the three facilities is shown in Figure 7-4. Using a best-fit linear projection from historic flows produces a flow projection of 19 to 20 MGD for the combined facilities in the year 2020. Many factors will affect the change in flow to the then wastewater facilities. These include 1) City efforts to reduce inflow/infiltration which would curb future flow increases and 2) redevelopment efforts which may tend to increase flow rates. The City will need to continue to ' monitor the effects of future change to the system. Since some of these features act to effect the individual efforts and the magnitude of these changes is uncertain, we will work from , straight-line projection for this report. Additionally, these figures show the projected wastewater flows through the year 2020. These figures indicate that wastewater flows will continue to ' , ' , , ' ' 1 ' , increase. It is projected that in the year 2020, the combined ffow of the three facilities will average between 19 and 20 MGD.

Influent flow records for the City's three wastewater treatment facilities and the reclaimed water flow demand records were reviewed to estimate the difference in rates and volume between the two. The following paragraphs discuss the requirements for storage for the various operating conditions that the City will face as the system expands and usage increases closer to the seasonal low flows of the plants. 8.1 Wastewater Flow Variations The City's influent wastewater flow records for Marshall Street APCF, East APCF, and Northeast APCF from 1989 to present (excluding the EI Nino impacted months in later 1997 and early 1998) were evaluated to estimate the seasonal wastewater flow variations. Figure 8-1 illustrates the typical monthly variations in flow throughout the year. The flow pattern was adjusted to reflect the current average wastewater flow rate of 15.4 MGD. 8.2 Reclaimed Water Demand Variations McKim and Creed reviewed the City's existing reclaimed water demand for the year, beginning May 1999, to estimate the seasonal variation in reclaimed water demand. The flows were generally in the 1 to 2 MGD range. This is the reclaimed water demand as measured flowing from the Marshall Street and Northeast APCFs. The seasonal demand pattern shown on Figure 8-1 was adjusted so that the average yearly reclaimed water demand matches the average flow rate of treated wastewater of 15.4 MGD. The seasonal peaking factor for the reclaimed water system, based on the curve shown in Figure 8-1 is 1.5. As a comparison, potable water demand from mid 1994 to mid 1999 ' was reviewed to determine an average seasonal peaking factor. The average seasonal peaking factor for the potable water system is calculated to be 1.1. The reclaimed water seasonal peaking factor is expected to be greater than the potable water seasonal ' peaking factor since the use of reclaimed water is more dramatically impacted by wet weather and dry weather conditions. � , Review of Reclaimed Water Master Plan Update City of C/earwater ' 0992-0072 December 2001 Page 21 ' � ' � � ' ' , , �' ' ' ' ' � ' ' , 9.0 STORAGE REQUIREMENTS Storage of reclaimed water is necessary, at a minimum, to meet daily demands by the reclaimed water customers. If the City wishes to maximize the use of reclaimed water while reducing or eliminating effluent discharges, then reclaimed water will need to be stored during the wet season in order to meet the demand during the dry season. These types of storage requirements are discussed below. 9.1 Seasonal Storage Requirements 9.1.1 Storage Requirements for Build Out of Urban Reclaimed Water System Wastewater treatment plant flows for the City's three wastewater treatment plants are projected to average 20 MGD in 2020. If the City wishes to build out their urban reclaimed water system to an average reclaimed water demand of 20 MGD, then seasonal storage of reclaimed water during the wet season is necessary to meet demands during the dry season. To estimate the amount of reclaimed water that would need to be stored in 2020, the average flow shown on Figure 8-1 (15.4 MGD) for reclaimed water supply and demand is adjusted to match to the projected average flow of 20 MGD as shown on Figure 9-1. The difference between the supply and demand volume was calculated to estimate the reclaimed water deficit or reclaimed water excess. This estimate was created assuming the City does not provide 3 MGD of reclaimed water to Pinellas County in 2020 to illustrate a worst case reclaimed water storage scenario in the event the 12-year City/County agreement is not extended. Figure 9-1 indicates that during a year, the City could see an approximate 1.1 billion gallon (BG) deficit in dry season demand of effluent indicating that the City would need to store 1.1 BG during the balance of the year to meet the reclaimed water demand. Building out the urban reclaimed water system and related storage will decrease the amount of effluent discharged to surface waters.

This storage requirement is lower because constant demand for reclaimed water has a dampening effect on the seasonal reclaimed water demand, whereas varying demand from urban reclaimed water customers (i.e. more demand in the dry season, less demand in the wet season) amplifies the seasonal demand for reclaimed water. Figure 9-2 shows the projected seasonal reclaimed water supply and demand in 2020. 9.1.3 Storage Requirements with 3 MGD to Pinellas and Balance to Urban Reclaimed Water System If in 2020, the City continues to provide 3 MGD of reclaimed water to Pinellas County and uses 17 MGD for the urban reclaimed water system in 2020, then it is estimated that the City will need to store 900 MG of reclaimed water to meet seasonal demand. Figure 9-3 shows the projected seasonal reclaimed water supply and demand in 2020 with 3 MGD of reclaimed water dedicated to Pinellas County. 9.2 Daily Reclaimed Water Storage Reclaimed water storage is necessary to meet daily fluctuations in reclaimed water demand. It is recommended that the City have reclaimed water storage at least equal to the volume of reclaimed water demand on a daily basis. The Marshall Street, East, and Northeast APCFs have capacity to treat average wastewater flows of 10 MGD, 5 MGD, and 13.5 MGD, respectively, equaling 28.5 MGD. The projected year 2020 flow is approximately 20 MGD. Currently, the Marshall Street facility has a 5 MG reclaimed water storage tank. The Northeast facility has a 5 MG reclaimed water storage tank planned to be on line in late 2002. The East facility has no reclaimed water storage.

Those tanks are Dei Oro (1 MG), Otten , Street (1 MG), and South Greenwood (1 MG). The Del O�o tank is expected to be converted to a reciaimed water storage tank as part of the Drew-Union Street project. r�l l ' , ' ' ' t , ' , , ' , , ' �i �.1 The locations of the Otten Street and South Greenwood elevated tanks are not conducive to converting these tanks to reciaimed water use in the near future. An additional 10 MG is needed to achieve the full 20 MG of daily reclaimed water storage. The City should consider addition of a 7.5 MG storage tank near the Clearwater Air Park to provide additional storage for flow from Marshall Street and East APCF's. A second 5 MG storage tank at the Northeast APCF should be considered to provide the added capacity to handle the total 20 MG projection. Table 9-1 is a listing of these storage facilities and related volume. These facilities are shown on Figure 9-4.

A Florida ' Department of Environmental Protection (FDEP) requirement (Rule 62-610.464, F.A.C.) stipulates that at a minimum, "this capacity shall be the volume equai to one day flow at ' the average daily design flow of the treatment plant or the average daily permitted flow of the reuse system, whichever is less." This requirement was implemented so that , reclaimed water could be stored then recycled through the wastewater treatment facility prior to it being distributed in the reclaimed water system. ' Reject storage is not an immediate issue with the City because surface water discharge points for treated effluent currently exist and the current operating permit does not ' require reject storage. However, due to more stringent FDEP regulations on surface water discharges, reject storage could become a pressing need and require ' consideration in planning for the future.

A review of existing rectaimed water systems in the City indicates that when reclaimed water becomes available, the total reclaimed water used in a service area exceeds the measured potable water consumption prior to reclaimed water availability. This is a result of replacing unmetered individual well use with reclaimed water and the fact that reclaimed water is less restrictive than potable water use. The current policies restricting reclaimed water usage will be continually scrutinized by the City to balance the objectives of development of reclaimed water systems in the City. The City's domestic and irrigation meter accounts were reviewed to determine potable water usage for several reclaimed water service areas from June 1997 through May 1998. A"domestic" meter records the amount of potable water used for bathing, drinking, washing dishes and clothes, and other in-home activities. An "irrigation" meter records the amount of potable water utilized for irrigation. The majority of the customers have a domestic meter, many customers have an irrigation meter in addition to the domestic meter, and very few customers only have an irrigation meter. McKim & Creed reviewed domestic and irrigation meter usage in the Harbor Oaks, Del Oro, and Coachman Ridge reclaimed water service areas. In the Harbor Oaks reclaimed water service area, an average potable water usage of 712,000 gpd for all customers was recorded from June 1997 to May 1998. Additionally, these meter records indicate that Harbor Oaks' residential customers used 183 gpd / account for domestic uses (478 accounts) and 315 gpd / account for irrigation (94 accounts). The City's meter records for the Del Oro reclaimed water service area from June 1997 to May 1998 indicate that the average potable water usage for all customers was 270,000 gpd. Additionally, these meter records indicate that Del Oro's residential customers used on average 196 gpd / account for domestic uses (581 accounts) and 134 gpd / account for irrigation (135 accounts). Review of Reclaimed Water Master P/an Update City of Clearwater 0992-0072 December 2001 Page 31 ' , City meter records for the Coachman Ridge reclaimed water service area from June 1997 to May 1998 indicate that the average potable water usage for all customers was � 241,000 gpd. Additionally, these meter records indicate that Coachman Ridge's residential customers used on average 201 gpd / account for domestic uses (648 , ' ' ' L_J , ' ' ' , , ' ' ' ' accounts) and 238 gpd / account for irrigation (125 accounts). This information is tabulated in Table 10-1.

The comparison indicates that the potable water offset is over 50% of the total projected reclaimed water usage. This information was utilized to project the potable water offset for the other reclaimed water service areas. Using the estimate of 50%, the reclaimed water service areas have estimated potable water offsets as shown in Table 10-2.

The cost / benefit ratio is the cost of constructing reclaimed water infrastructure for a service area divided by the benefit (i.e. potable water offset) for the service area. A lower cost / benefit ratio is preferred since it is advantageous to have a greater potable water offset relative to the cost of constructing a reclaimed water system. The cost / benefit ratio is calculated by multiplying the capital cost of the reclaimed water project by an Review of Reclaimed Water Master Plan Update City of Clearwater 0992-0072 December 2001 Page 33 , ' i lJ � ' � ' ' , �J ' �I! , ' l_J � � amortization factor (in this case, 30 years at 8% interest = 0.0888) and dividing by the potable water offset (in thousands of gallons per year) projected for the project. The capital cost used for the purposes of establishing the cost/benefit ratio includes the cost of constructing distribution systems in the service areas and a prorated cost of all transmission, storage and pumping required to extend services to a particular area. The actual cost of construction of a given project is included in Table 10-5. For example, the cost / benefit ratio for the Seville/Sunset Drive reclaimed water service area is calculated by the following equation: Cost / Benefit = ( $2,200,000 * 0.0888 * 1000 gal ) / ( 265,000 gpd * 365 days ) _$2.00 / 1000 gallons of potable water The cost / benefit ratios for the 25 different reclaimed water service areas are shown in Table 10-3 in increasing order. Projects are ranked based on this order and are shown in Figure 10-1.

The phasing of these reclaimed water projects must be considered if reclaimed water is not yet available from ' the related wastewater treatment facility. For example, the Northeast Advanced Pollution Control Facility (APCF) currently produces an average of 6 MGD (million ' gallons per day) of reclaimed water as shown in Figure 7-2. Minimum flows were approximatefy 5 MGD during drought conditions in May and June 2000. An average of 1 ' MGD of reclaimed water is allocated to the following areas: Countryside Golf Course, Chi Chi Rodriquez Golf Course, Countryside Golf Driving Range, and Countryside ' Sports Complex. Another 3 MGD will be allocated to Pinellas County's reclaimed water system for 12 years as part of an agreement developed in 2000. ' ' ' , ' ' ' t ' ' �J The next project slated for reclaimed water from the Northeast APCF is the Drew / Union Streets project. It is projected to utilize an average of 0.55 MGD of reclaimed water. The distribution of reclaimed water from the Northeast APCF is shown below in Table 10-4. Table 10-4 illustrates that following the Drew Street / Union Street project, a minimal amount of reclaimed water will be available to serve future reclaimed water service areas in the proximity of the Northeast facility.

The projected demand of 0.33 MGD for Seville can be met by the flows from the Northeast APCF and the system can be easily ex�ended from the transmission main system that is part of the Drew/Union project. In addition, the Sunset Drive area of Clearwater Harbor has significant potable water use for irrigation. We recommend that this segment be included with the Seville area project since the cosUbenefit of these combined areas is lowest. The projected demand of 0.26 MGD for the Sunset Drive area will be provided from the Marshall Street facility, which currently has ample capacity for this additional area. It is recommended that a reclaimed water pumping station be constructed at the East APCF so that reclaimed water produced by the East facility may be used in the reclaimed water system. It is expected that the availability of reclaimed water from the Northeast APCF for use by the City's east reclaimed water service areas will become limited, therefore, reclaimed water from the East APCF will be necessary prior to other areas in the eastern portion of the City being brought on-line. The proposed phasing and associated costs of the reclaimed water projects, along with the pumping and storage facility recommendations through the year 2020 are shown in Table 10-6. Table 10-7 shows the cumulative average reclaimed water demand projected through 2020. This average demand will require seasonal storage to meet seasonal peak demands. A comparison was made between this cumulative reclaimed water demand and the projected average reclaimed water supply through 2020 if the proposed schedule for bringing reclaimed water service areas on line is followed. This comparison is itlustrated in Figure 10-3 and indicates that there will be a net excess of less than 1 MGD of reclaimed water in 2020.

Currently, the Marshall Street APCF discharges treated wastewater into Stevenson Creek, which flows to Clearwater Harbor, and the Northeast and East APCFs discharge to Old Tampa Bay. Several options for a zero discharge system were considered including land application for large users (e.g. golf courses, parks), high rate land application (i.e. spray fields), rapid infiltration basins (RIBS), and bulk sale of reclaimed water to Pinellas County and / or other municipalities coupled with evaluating non-discharge alternatives, storage basins, tanks, and aquifer storage and recovery (ASR). ASR facilities were evaluated to support the storage required under non- discharge scenarios. Achieving zero discharge during the wet weather events will be challenging because wastewater flows to the treatment facilities generally increase during wet weather events due to ' infiltration and inflow in the collection system, and the reclaimed water demand is lower during wet weather. Zero discharge can be achieved by storing the reclaimed water unused during wet ' weather. This stored reclaimed water can then be utilized during the dry season to supplement the reclaimed water produced by the wastewater treatment facilities to meet demand. ' , , ' ' ' ' ' i 11.1 Land Application Several sites in the City have been identified as areas to receive reclaimed water at set irrigation rates. These areas are divided into slow-rate land application areas (public access and restricted public access areas) and rapid-rate land application areas. 11.1.1 Slow-Rate Land Application, Public Access Areas The slow-rate land application, public access areas are generally open space areas utilized by the public for recreation (e.g. golf courses, parks, sports fields) and are projected to utilize an average of 1" per week of reclaimed water. Currently, the City provides reclaimed water to slow-rate land application, public access areas including Memorial Causeway, Coachman Park, Jack Russell Stadium, Philip Jones Field, Countryside Golf Course, Chi Chi Rodriquez Golf Course, Driving Range at Countryside, and Countryside Sports Complex. The Drew-Union Street project currently under design will provide reclaimed water to the following slow-rate land application, public access areas: Chesapeake Field, Review of Reclaimed Water Master Plan Update City of Clearwater 0992-0072 December 2001 Page 42 , , ' ' , ' � ' ' , , ' ' , ' ' ' ' , Eddie C. Moore Complex, St. Petersburg Junior Coilege, Carpenter Field, and Sylvan Abbey Memorial Park Cemetery. Other areas have been identified in the City that meet the criteria for slow-rate land application, public access areas. The areas are shown on Figure 11-1 and include the following: Clearwater Air Park Golf Course, Countryside Executive Golf Course, Glen Oaks Golf Course, David Martin Soccer Field, Sid Lickton Park, Crest Lake Park, Ed Wright Park, Ross Norton Complex, and Clearwater Muriicipal Cemetery. The total acreage for these slow-rate land application areas is estimated to be 370 acres. Using the land application rate of 1" per week, it is estimated that approximately 1.42 MGD can be utilized by these areas. 11.1.2 Slow-Rate Land Application, Restricted Public Access (Spray Irrigation) Two areas within the City of Clearwater that have been identified for slow-rate land application, restricted public access are Florida Power Corporation's Power Line Right of Ways (ROWs) and greenspace areas at the Northeast APCF. These areas are identified on Figure 11-1. An option that has been evaluated is a spray irrigation system with an application rate of 2" per week for the areas discussed above. The 2" per week application rate is the conservative maximum annual hydraulic loading rate recommended in F.A.C. 62-610, Reuse of Reclaimed Water and Land Application. The Florida Power Corporation ROWs and Northeast APCF areas total approximately 176 acres, which equates to an application of approximately 1.37 MGD. 11.1.3 Rapid-Rate Land Application (Rapid Infiltration Basins) McKim & Creed has identified Florida Power Corporation's Power Line ROWs and greenspace areas at the Northeast APCF as possible sites for rapid-rate land application. Rapid infiltration basins (RIBS) are a rapid-rate land application option that allow for an application rate greater than spray irrigation. For this report, McKim & Creed utilized an average application rate of 3" per day as outlined in F.A.C. 62-610. It is projected that the RIBS will cover an area of approximately 45 acres within Florida Power Corporation's ROWs, which equates to an application of approximately 3.67 MGD. The RIBS are proposed to be located between the power line towers, sized approximately 700 feet by Review of Reclaimed Water Master Plan Update City of C/earwater 0992-0072 December 2001 Page 43 � -� � � � n r � D � D � m � � � m D � N Q � O � � n r D � f�l � D ---I m T1 N -< � -� m � � m < mC C � �� tA -,� � � � � -II � � � � N m v � � v D -D � r n D � O Z D � r� D N � D� D� �(n tn W�C7 �tTl Z7fTi D� r OD� Dr D� �D � Z�� D D �� 1 p�0 ap- �- I � � � D '�7 Z� �� D� r�T1 �.Zm7r p� Z`� �G� Sf*7 � D � D D �D D— Z m �� � aZ � DD :0 --i � � �� � D� < s � � m m D D � � o Z Z r m G� r� z � 0 � m � � z z � � � � � 8 0 � ... ... .... .... ........ . .. . . . . .. .. .. . .. . . ... .... . .... . . _ .. . .. . . _ ... . . . .. . . _ .. .. ... . __ ... ... . .... .. _"_"__ I� N ` �r + �;����-. �"� v� .,« � � _; � �� _, ----- �,��, � � , __ _r __�— — — � t� .,� _ _ --------� ' -� _.��� �/I I(nl�iJ ��r i�., I, c JG ��; . � t� r//�/ ,�i� � �� :� �, I I, :� .� t,���-,�°"� 4� _ , ` _ -_ .

Within the Northeast APCF property, RIBS are estimated to cover 21.7 acres, which equates to an application of 1.77 MGD. The total reclaimed water volume handled by the RIBS system would be a maximum of 5.4 MGD. Table 11-1 below is a comparison of the land application systems within Florida Power Corporation's ROWs and at the Northeast APCF.

The City is currently contracted to deliver 3 MGD of reclaimed water from the Northeast APCF to Pinellas County for a 12 year period. � The City of Clearwater may want to consider an emergency reclaimed water connection with another municipality. This connection could allow the City to serve its reclaimed ' water customers during severe dry weather conditions or in the event that the reclaimed water produced by the City fails to meet FDEP's water quality regulations. A connection with the City of Largo has been identified as a possible connection as shown in Figure , 11-2. This connection is approximately 6 miles long and is proposed to be 24-inch pipe. ' ' ' � The approximate cost for this pipeline is $4.4 million. The total cost will be approximately $5 million with the addition of high service pumps at Largo's wastewater treatment plant. Review of Reclaimed Water Master P/an Update City of Clearwater 0992-0072 December 2001 Page 45 11.3 Storage Basins or Tanks Section 8 provides a discussion of the seasonal variations in the availability of reclaimed water and the reclaimed water demand by customers. Based on the current average reclaimed water availability of 15.4 MGD and assuming a fully developed urban reclaimed water system, it is estimated that 820 MG of reclaimed water would need to be stored during the year to achieve zero discharge. Assuming a berm height of 40 feet for a lined storage pond, the City would need a minimum of 117 acres to store 820 MG of reclaimed water. The representative size of this pond is illustrated on Figure 11-3 in relation to the map of the City. Obviously, siting of a facility of this size will have a significant impact anywhere within the City. The total cost of the pond including the pond, pumping facilities, piping, engineering and permitting is estimated to be $52 million. This includes $32 million for the pond (including the pond, pumping facilities, and piping), $12 million for purchasing urban property (approximately $100,000 per acre), and $8 million for engineering and permitting costs. Section 9 is a discussion of the storage requirements for three different scenarios in the year 2020, including storage for a fully developed urban reclaimed water system (1.1 BG), storage for a fully developed urban reclaimed water system with 3 MGD sold to Pinellas County and 5.4 MGD discharged to the RIBs system (600 MG), and storage for a fully developed urban reclaimed water system with 3 MGD sold to Pinellas County (900 MG). The quantity of reclaimed water required to be stored is at a maximum when the reclaimed water is used primarily for the urban reclaimed water system. This is due to the seasonal variations in reclaimed water demand (more demand during the dry season and less demand in the wet season). The quantity of reclaimed water storage is reduced as more reclaimed water is discharged at a constant rate, such as to a land application system or a bulk purchaser (e.g. Pinellas County).

Several ASR projects are ongoing in the Tampa Bay area. An ASR system for reclaimed water is proposed in Hillsborough County. The ASR application for one ASR well has been approved by the Florida Department of Environmental Protection (FDEP). Testing will be completed on the well prior to approval of other ASR wells. The City of St. Petersburg has an expansive reclaimed water system and is pursuing ASR wells to store reclaimed water. They have received approval from the FDEP to drill and test one ASR well, and may be allowed by the FDEP to install and test future ASR wells based on the test results of this initial well. The well is constructed and will be cycle tested for two years. The feasibility and application process has taken three years to complete. A total of five years will have transpired from the start of this one ASR well approval process through the cycle testing. SWFWMD is investigating the potential for reclaimed water ASR wells in the Pinellas County area. The City of Clearwater has tentatively agreed to participate in a SWFWMD initiated project to investigate the feasibility of ASR storage in the Clearwater area. It is estimated that costs for reclaimed water ASR capacity are $700,000 for the first MGD. Beyond the first MGD, it is expected that ASR cost will be $500,000 per MGD. Further investigation of an ASR system is necessary to evaluate the potential ASR capacity of the aquifer system within the City. ASR may be the only practical alternative to meet the massive storage requirements of a non-discharge option and/or to develop the reclaimed water system beyond the 8 to 9.0 MGD daily average demand. 11.5 Wet Weather Discharge In severe wet weather events, it is expected that increased wastewater flows will enter the City's three wastewater treatment facilities and that the City will not be able to discharge all of the treated water (reclaimed water) to land application sites. McKim & Creed recommends that the City maintain the existing surface water discharge points as emergency discharge points. Review of Reclaimed Water Master Plan Update City of Clearwater 0992-0072 December 2001 Page 49 ' ' , ' ' u ' ' u ' ' �I�' � ' ' ' L_J ' L� 12.0 SCENARIOS Three scenarios have been developed for comparing approaches the City may wish to consider when developing its reclaimed water system. The basic components of these scenarios are described below and are a balance of the options discussed above. 12.1 Scenario 1—Urban Reclaimed Water System, Surface Water Discharge Scenario 1 includes building out the reclaimed water system such that the seasonal peak demand is equal to the projected reclaimed water availability of 20 MGD in 2020. This scenario includes providing 3 MGD to Pinellas County as part of the 12 year reclaimed water agreement and assumes that 3 MGD will be provided through 2020. Figure 12-1 shows this scenario and indicates that the average reclaimed water demand is approximately 13 MGD, with a peaking factor of about 1.5. About 10 MGD of reclaimed water will be available for the City's urban reclaimed water system and 3 MGD will be allocated to Pinellas County. It is estimated that 2.6 BG per year of excess reclaimed water will be discharged to surFace waters under this scenario. Table 10-7 indicates that reclaimed water can be delivered to the existing service areas and to the proposed reclaimed water service areas through the Lake Park project at the average 13 MGD reclaimed water demand. An advantage of this scenario is that the City will not need to construct additional storage facilities (e.g. storage tanks, ponds, ASR system) to store reclaimed water to meet seasonal demand. A disadvantage is that excess reclaimed water will be discharged to surface waters and the resource will not be utilized for future reclaimed water projects. Estimated costs for this scenario are $33,100, 000. The issue of greatest concern related to operating a surface water discharge is meeting surface water discharge standards. These standards will likely become more stringent in the future as more constituents of concern are monitored. The City received their renewed surface water discharge permits for Stevenson Creek and Old Tampa Bay outfalls in 2000. These renewed permits include discharge standards for constituents that have not been enforced in the past, namely copper and trihalomethanes (THMs).

The ' City's and County's potable water is slightly aggressive and causes corrosion of the potable water distribution system piping and to a limited extent, corrosion of the ' ' �J ' ' ' ' t 1 , ' , ' ' ' wastewater collection system piping. Corrosion of the piping may result in constituents of concern being dissolved into the water and wastewater, eventually leading to the wastewater treatment plants. If it is determined that improvements to potable water quality do not improve the quality of the wastewater, then reductions in the amount of constituents in the wastewater may be required at the wastewater treatment facilities. Costs for improvements to either potable water treatment or wastewater treatment have not been determined at this time. 12.2 Scenario 2— 5.4 MGD to RIBS, 3 MGD to Pinellas Co., Urban RCW System, Zero Discharge Scenario 2 includes discharging 5.4 MGD to a rapid infiltration basin (RIB) system, selling 3 MGD to Pinellas County, developing the City's urban reclaimed water system (11.6 MGD), and having no discharge of reclaimed water to surface waters except during extreme wet weather conditions. The advantage of discharging reclaimed water to the RIB system and providing water to Pinellas County is that the water is utilized at a constant rate which diminishes the magnitude of the reclaimed water demand variations during the year (i.e. high demand during dry weather months and low demand during wet weather months). In addition, a RIB system may enhance the surficial aquifer system by providing a constant source of recharge. Based on an 11.6 MGD availability for urban reclaimed water customers, the City would be able to develop the reclaimed water system through the East Drew Street project as shown in Table 10-7. At an average reclaimed water availability of 20 MGD in the year 2020, the City will need to store at least 600 MG of reclaimed water to accommodate the seasonal urban demand during the year. The projected annual variation in reclaimed water demand is shown in Figure 9-2. The costs associated with this scenario are provided in Table 12-1. Review of Reclaimed Water Master Plan Update City of Clearwater ' 0992-0072 December 2001 Page 52 , ' ' ' ' LJ 1 ' u , ' ' ' ' ' , ' ' ' Table 12-1 Scenario Z Capital Costs Action ' Cost 5.4 MGD to RIB System $8,600,000 3 MGD to Pinellas County - Urban RCW System (11.6 MGD) $25,200,000 600 MG Aboveground Storage $40,000,000 Total (20 MGD in year 2020)= $73,800,000 It is estimated that a storage pond large enough to hold 600 MG would be constructed on at least 90 acres. It is likely that this amount of contiguous, vacant property is not available within the City. Therefore, the City may want to consider an ASR system in place of or in conjunction with above ground storage. The costs for an ASR system that could accommodate 600 MG of storage a year is as follows: Table 12-2 Scenario 2(w/ ASR) Capital Costs Action Cost 5.4 MGD to RIB System $8,600,000 3 MGD to Pinellas County - Urban RCW System (11.6 MGD) $25,200,000 600 MG ASR (max. storage = 6.62 MGD) $6,510,000 Total (20 MGD in year 2020)= $40,310,000 The capital cost savings of Scenario 2 with an ASR system are estimated to be $33 million. Due to this difference in cost, it is recommended that an evaluation of an ASR system within the City of Clearwater be conducted to determine system feasibility. 12.3 Scenario 3— Urban Reclaimed Water System, Zero Discharge Scenario 3 includes fully developing the urban reclaimed water system (20 MGD) and providing for storage of reclaimed water (1.1 BG per year). Full development of the urban reclaimed water system is defined as providing a yearly average reclaimed water volume equal to the yearly average volume of treated wastewater. Table 10-7 indicates that reclaimed water can be delivered to the existing service areas and to the proposed reclaimed water service areas at least through the North Belcher project. Review of Reclaimed Water Master Plan Update City of C/earwater 0992-0072 December 2001 Page 53 l _J � ' � ' ' ' l� J ' ' ' ' , � ' ' ' ' ' Development of this system provides several challenges, including providing uninterrupted reclaimed water service to customers during those dry weather months when the demand for reclaimed water is greater than the yearly average reclaimed water supply. Equally challenging is providing storage for reclaimed water during the wet weather events when customers reduce their demand for reclaimed water. As discussed in Section 9.1, the City needs to store 1.1 BG per year for a zero discharge system. Approximately 160 acres would be necessary to construct a storage pond able to hold 1.1 BG. A breakdown of the costs for this system are provided below: Table 12-3 Scenario 3 Capital Costs Action Cost Full Development of Urban RCW $62,500,000 System (year 2020) 1.1 BG Above Ground Storage $70,000,000 Total (20 MGD in Year 2020) _ $132,500,000 Similar to Scenario 2, the City may want to consider an ASR system to replace or supplement above ground storage. The costs for the reclaimed water system with ASR are the following: Table 12-4 Scenario 3(w/ ASR) Capital Costs Action Cost Full Development of Urban RCW System (year 2020) $62,500,000 BG ASR Storage (max. storage = 10.94 MGD) $10,670,000 Total (20 MGD in Year 2020) _ $73,170,000 The estimated capital cost savings with an ASR system are about $59 million. As discussed above in Scenario 2, the feasibility of an ASR system would need to be investigated prior to implementation of a program. Review of Reclaimed Water Master P/an Update City of Clearwater 0992-0072 December 2001 Page 54 1 ' , � ' 1 �J C�' ' ' , ' ' CI' ' ' ' 1 ' 13.0 CONCLUSIONS The City's reclaimed water system was evaluated to rank the reclaimed water service areas established in the Reclaimed Water Master Plan Update (McKim & Creed, 1998) based on a cost / benefit ratio. The ranking indicates that several of the reclaimed water service areas in the east portion of the City are priority projects. In order to bring these projects on line, the City should consider constructing an East-West Interconnection within the next few years due to the projected deficit of additional reclaimed water from the Northeast APCF as shown in Table 10-5. This will allow for greater utilization of the reclaimed water from both the Northeast and Marshall Street APCFs. Additionally, a pump station at the East APCF should be considered shortly after construction of the East-West Interconnection to allow for utilization of reclaimed water from that facility. Storage facilities at or near the Northeast and Marshall Street APCFs are proposed within the next 20 years. Three scenarios for managing the City's reclaimed water were evaluated in Section 12. Of the three scenarios, Scenario 1 has the least expensive capital costs ($33.1 million). This option includes building out the reclaimed water system such that the seasonal peak demand is equal to the projected reclaimed water availability of 20 MGD in 2020 and providing 3 MGD of reclaimed water to Pinellas County. Under this option, excess reclaimed water will be discharged to surface waters. The estimated capital costs for Scenarios 2 and 3 are greater than for Scenario 1. Scenarios 2 and 3 are zero discharge alternatives, which may become an important issue if surface water discharge standards become stringent to the point of requiring additional treatment of the wastewater prior to discharge. If that is the case, then the costs for additional wastewater treatment should be compared to the costs for a zero surface water discharge system. It appears that utilizing an ASR system for storage of reclaimed water can provide cost savings. Further evaluation of the feasibility of an ASR system is necessary prior to implementation. Review of Reclaimed Water Master P/an Update City of Clearwater 0992-0072 December 2009 Page 55 , ' � �� ' 1 ' lJ 14.0 RECOMMENDATIONS It is recommended that the City continue to build out its reclaimed water system as outlined in the prioritization plan herein. This plan will allow the City to minimize the impact to its budget, evaluate the actual reciaimed water usage of each service area, and be more likely to receive cooperative funding from SWFWMD since they typically fund one project per municipality per year. It is recommended that the City follow the reclaimed water service area ranking provided in this report since SWFWMD ranks cooperative funded projects on a cost / benefit ratio. The City should maintain its current surface water discharge and should continue to pursue the alternative treatment methods and permit compliance improvements currently underway to address the more stringent discharge limits. The continued discharge will allow a more ordely development of reclaimed water infrastructure and allow the City time to evaluate seasonal storage alternatives. While the City is proceeding with its reclaimed water program, it is recommended that the ' feasibility of ASR be evaluated. It is understood that SWFWMD is encouraging municipalities to evaluate the potential for ASR projects and is providing cooperative funding for feasibility , studies and related design, construction, and cycle testing of ASR wells. The lack of available land for above ground storage and the potential for more stringent requirements on surface , ' ' ' water discharges supports the recommendation to further evaluate the potential of ASR. Based on the reclaimed water projects and phasing shown in Table 10-7 and the availability of reclaimed water as shown on Figure 7-4, it is estimated that the City's peak reclaimed water demands can be satisfied without seasonal storage or further usage restrictions when the average reclaimed water demand is no more than 12 MGD (9 MGD to urban customers and 3 MGD to Pinellas County). This would bring reclaimed water to the projects listed in Table 10-7 through the Morningside project, which is projected to begin construction in 2006 and be on line in 2008. The City will need to continue to evaluate supply and demand projections for reclaimed water and may be required to implement further restrictions to continue expansion of the system , beyond the 2008 time frame without a major seasonal storage capability. Due to the lengthy evaluation, permitting and ASR well cycle testing process, it is recommended that the City begin , ' ' ' studying the feasibility of a reclaimed water ASR system. Additionally, the City may wish to consider pursuing reclaimed water storage projects with other municipalities to help meet seasonal demands. Review of Reclaimed Water Master Plan Update City of Clearwater 0992-0072 December 2001 Page 56 , ' 15.0 IMPLEMENTATION PLAN ' ' It is recommended that the City foilow the reclaimed water service area implementation program as shown in Table 10-5. The City Commission should approve the Cooperative Funding Agreement with the Southwest Florida Water Management District for funding of the Harbor Oaks Reclaimed Water System in early 2002 and should simultaneously authorize City staff to move forward with the project. The City should prepare the application for FY 2003 funding for � the next priority project — Seville/Sunset Drive Reclaimed Water Project as outlined in this plan. In addition, it is recommended that the City contribute to the ASR preliminary feasibility study ' with the Southwest Florida Water Management District to begin evaluating options for seasonal storage of reclaimed water. The City should review and update the 6-Year Capital Improvement ' Plan to reflect adequate funding levels for reclaimed water projects based on this plan. , ' � ' ' ' ' lJ ' ' ' Review of Reclaimed Water Master P/an Update City of Clearwater ' 0992-0072 December 2009 Page 57 ' ' 1 ' ' ' � �� � 1J ' ' ' , ' C � , Appendix A Comparison of Current to Previous Ranking Review of Reclaimed Water Master Plan Update City of C/earwater ' 0992-0072 December 2009 Page A-9 , 1 ' L' ' ' 1 TO: FROM: MEMORANDUM Mayor & City Commissioners .

Attachr City of Clearwater ' . 2001 Reclaimed Water Master Plan Update Response to Commission Questions May 21, 2001 Were only three neighborhood's irrigation usage reviewed to develop the Master Plan? Irrigation usage for metered customers was collected for the entire City for evaluation. Three areas were selected to study in detail to ascertain the estimated potable water offset that one might expect if reclaimed water were made available under the current program, since only a fraction of City customers have separate irrigation meters. Many areas of the City have very few irrigation accounts, with many using shallow wells and others simply irrigating from their single potable water metered connection. Evaluating areas with higher percentages of irrigation meters allows us to compare expected usage at the higher rates assuming the lower cost of reclaimed water and the current availability charge to promote participation. The only actual data on irrigation usage currently available directly is through review the metered irrigation usage for those that have irrigation accounts. Attached to this response is a Table that was utilized in the 1998 report and as data for refinement of the current planning document that outlines metered irrigation usage for all of the areas in the City. For what purpose will reclaimed water be utilized in the Town Pond project? , Reclaimed water may be utilized in the Town Pond project for irrigation of green space in lieu of using potable water. Reclaimed water would be utilized in City areas as well as any surrounding developments that will have landscaping and green space. It is recommended that pipelines for ' reclaimed water be installed as this area is developed. Reclaimed transmission mains will be located near the intersection of Cleveland and Missouri as part of the proposed Greenwood Corridor Enhancement project. ' ' ' , ' ' ' What is the history of neighborhood petitions for reclaimed water service? The City's original ordinance pe�taining to reclaimed water provided for reclaimed water extension at the discretion of the Public Works Administrator for areas that petitioned the City for service. In the planning efforts represented by the 1998 Master Plan Update, the City modified the approach to expansion of the reclaimed water system to be based on a prioritization based on such factors as potable water offset, cost, and location proximate to existing facilities in addition to public receptiveness to reclaimed water. Building a system solely based on petitioning can lead to significant costs in the early stages of the system development and to very inefficient construction and operation. Coachmen Ridge has indicated to the City in the past that the neighborhood desires reclaimed water. Due to the central location of Coachman Ridge with respect ,to the three water reclamation facilities, conveying reclaimed water to this area will be relatively expensive until pipelines and pumping facilities are in place. Progress is being made in this regard given the No�theast Storage and Pumping Facility project beginning construction and design being initiated on the D�ew-Union Street transmission mains. C:\WINDOWS\TEMPWttch A.doc C� , ' ' ' , ' , IJ ' �� , , ' � ' ' ' r-, � Aicac} What percentage of potable water revenue lost due to reduced water demand will be offset by increased reclaimed water revenue? As this question illustrates, the sale of potable water goes down as reclaimed water use offsets the potable water use. The revenue generated by the sale of reclaimed water does not offset the lost revenue from potable water in the strictest sense. Reclaimed water revenue does offset reclaimed water system operating costs and some capital costs. As we had presented in the graphic illustration of capital costs sources, the majority of reclaimed water capital costs are borne by the Water and Sewer fund with some assistance from outside grant funding when projects are selected for funding by the Southwest Florida Water Management District. Reclaimed water system development is extremely costly and is typically not a self-sufficient enterprise. As an example of the financial impact, consider the recently developed Island Estates area. As a result of the new reclaimed water system operation, the loss of potable revenues over the last year is $413,300. This is based predominantly on the reduction of sales of potable water through irrigation meter accounts. For the same time period, the revenues generated through sales of reclaimed water was $122,550 for the past year. This influence was factored into the previous rate study conducted to include not only Island Estates, but also the areas programmed to be on-line within the planning horizon. Are deep wells and shallow wells included in Table 10-3 of the Draft Repo�t? The numbers of wells represented in the report are the wells that are permitted and included in the database of SWFWMD. These permitted wells would include deep wells and shallow wells, however the vast majority are shallow wells withdrawing water from the su�cial aquifer. The total number of wells in any given area may exceed the information presented in the table. This data was used as a guide for developing estimated irrigation usage in a relative sense. This data will be reviewed and adjusted if appropriate to estimate the full offset of groundwater usage and potable water usage. What influenced the changes in the priority of service areas? The primary factor influencing the differences in the prioritization are the changes that the Southwest Florida Water Management District made in its evaluation criteria for funding reclaimed water projects. In the last two years, the criteria has become much more stringent from the standpoint of the cost of a project compared to its benefit expressed in terms of offset of potable and/or ground water. The Master Plan in 1998 considered this heavily, but also considered a few more issues including public acceptance, proximity to sources of reclaimed water and availability of alternative sources of irrigation water. With project funding so heavily contingent on the Cost/Benefit ratio and having success with the availability charge in securing greater than 50% participation in a given area, the most recent update relies on the cosUbenefit ratio more heavily than the 1998 plan. Additionally, in 1999, facing this revised criteria, the City opted to propose the Drew and Union Street project that was more competitive for grant funding since it focused on larger tracts of irrigable space without the large cost for distribution piping like you would see in a residential project area. With this project moving forward, the transmission facilities constructed will favor areas that are in proximity to the new transmission system. This project also allows the City to accelerate interconnecting the three treatment facilities to provide a greater operational flexibility and reliability. A table is attached that shows the comparison befinreen the previous rankings and the currently proposed prioritization. A separate table also outlines the costs of out-year projects at their escalated capital costs. Escalation of costs must be considered in preparation of Annual Operating and Capital Improvements Budgets as well as rate evaluations. Previous budgeting and rate studies did in fact include escalation of costs. For purposes of prioritizing and comparing options, present costs are more appropriate to use.

The meeting was scheduled from 630 p.m. to 830 p.m. on Tuesday August 7, 2001. The purpose of the meeting was to assess the reaction of the neighborhood to the new location for the water plant and to provide information on the revised reclaimed master plan to the general public. City Staff Attendees: Bill Horne, Garry Bnunback, Mahshid Arasteh, Anc�y Neff, Joe Reckenwald, Dave Sickler, Glenn, Daniel, Andy Bachtel, and Tom Miller. Consultant staff: Street Lee, Mitch Chiavaroli, Jack Hicky, and Joe Hughs. Advertisements: Posted by Ciry Clerk's office C-View Press Release Website Variable Message Board St. Pete Times (Clearwater) Sunday & Tuesday�' * The ad for Tuesday did not run. It actually ran on Wednesday, one day late and the Ciry will not be charged. The room was set up with stations showing the water plant relocauon, building appearance, costs, timelines and , other displays relevant to the new water treatment faciliry. Other displays included geology of the area, reclaimed water and a table with handouts conceming grease. , ' i ' ' i Tumout was light, thirteen people attended. Of the 13 who signed, one was a Commissioner (Jonson) and one was Asst. City Manager, Garry Bnunback and two were ciry employees. As residents entered they were asked to sign in and were given a fact sheet and a comment sheet. As each resident left, they were asked if they would like to return the comment sheet. WATER PLANT CONIMENTS /QUESTIONS One resident asked if this project was moving forward for development purposes. We explained the project was based on economics not intended to support future development needs. The water plant will produce water at $1.68/ 1000 gallons. Currently we purchase water from Pinellas County at $1.79/ 1000 gallons and that price is going to rise. Based on quantiry of water anticipated from the plant, and the difference in price of water produced and water purchased, substantial economical savings will be realized. Ms. Rita Garvey, who previously had concerns about the water plant location, indicated she would support the new location since it was less obuusive and fit into the surroundings better than the previous plan. Other general comments and questions were: Why not build the water plant sooner? , The new location makes sense. The new building is much improved over the previous metal building. � August 7, 2001 Pa�e #. , ' , ' � �_J ' l.� � , ' �� , , ' , L [� � Attachment C Overall, it is a good plan & project and my questions were answered. RECLAIMED WATER COMMENTS/QUESTIONS Following is a generalized summary of the questions asked and answers provided by staff. Why can't you do more? ANSWER Staff explained the reclaimed master plan, how a cost/benefit analysis was developed and how it was used to prioritize areas. Staff also discussed opportunities for co-funding grants from the SWFVUMD to offset and reduce the costs of the projects. The total cost of the 20-year program exceeds $100 million dollars. The projects are spread out due to the cost and to maX;m»e SWF\`UMD funding. What are the criteria for bringing reclaimed water to an area? Why are areas in the order that they are? ANSWER: Criteria are: proximity to existing infrastructure, cost/benefit analysis, potable water offset, high irrigation use, customer demand, and number of shallow wells in area. The areas are in the order shown because those at the top have the best cost/benefit analysis. SV�IFV�IMD prioritizes projects based on a cost/benefit ratio. The City must remain competitive for future grant funding. Why is the master plan so long (20 years)? ANSWER To take advantage of SWF��INID grant funding and offset the cost to our customers as much as possible and to spread out the costs over time. Why did the City run the reclaimed water to the beaches first? ANSWER: The infrastructure was run to Island Estates iu-st, north Clearwater Beach second and south Clearwater Beach third. These areas were first because they had the lowest cost/benefit analysis and very high potable water offset. When is reclaimed water coming to my subdivision? ANSWER It depends where your area is according to the revised reclaimed Master plan. Does reclaimed hurt animals (dogs & cats) if they drink it� ANSWER No, they have different digestion systems, in small amounu it should not harm them. However, we advise people not to purposely fill their pets bowls with reclaimed water. Does reclaimed water smell? ANSWER: Sometimes, depending on the level of chlorine. Wlry not spend all the money for the water treatment plant on the reclaimed water system? ANSWER 'The plant will produce 2 million gallons/day of water. If the same amount were spent on the reclaimed system we would not realize the same potable offset benefit. The same amount of money to produce 2 mgd of potable water would only provide 0.7 mgd of reclaimed water. Building the water plant is a better investment in terms of producing more potable water while purchased water costs will continue to rise. When (year) will all the reclaimed water be used up? ANSWER Appro�cimately 2007-2009 if no action is taken to conserve the resource. Why are we selling reclaimed water to Pinellas County? ANSWER At the tune the agreement was approved reclaimed water was not considered a resource as it is today. Based on the previous master plan, the amount provided to Pinellas County was in excess of City needs for the duration of the agreement. Additionally, there is not yet an extensive reclaimed infrastructure in the northeast part of town. au�USt �, Zoo i Page #. � � � � � � � � � � i � � � � � � � � o i/t t � in a r.rc � .au o wm �mo �mo �000 �a000 �GIL M /Qi LEGEND ---- - arr oF aFnRw��R WATER SERVICE AREA BWNDARY n^ ^�^*ti� ADVANCED POLlUT10N CONTROI � ' FACIUTY �,?� EX1571NG RECLAIMED WATER SYSTEM � YEAR CONSTRUCiION BEGINS RECLAIMED WATER SERVICE AREA 80UNDARY � PENDINC RECLAIMED WATER SYSTEM � � � DUN�IX -. r (, ' ,, `�i `t `l.j,•2, � . /�.i''.%; \ . � r, . �� ii � , _. ..._ . __._._ �. � ....� Attachmeilt D �` — �� �-� �` _ � \\�� )�owa�tax .� 4��- ��--� :t � � � ., .� � � ., _ > ���, ��j. �: , r.. . . ?s., � -� :�,`.!:�. . � F�cwn .�... .� It7R1l6M�CI�IMGE �� NOMHq►ACil�f� ! f ' �.
