(i".' ~. .... ",.' ," ~, , I I Page 2 of 34 Description of project in terms of type of treatment, flow capa<;ity, and process units: The Clearwater Northeast Wastewater Treatment Facility will provide capacity to process an average of 8 mgd of raw wastewater to the required degree of advanced treatment, and will process an additional 8 mgd of secondary effluent from existing plants to the AWT standards. The 8 mgd portion of the plant will include mechanical screening, aerated grit removal, primary clarification and high-rate activated sludge processes. The 16 mgd portion of the plant will include suspended growth nitrification and denitrification, multimedia filtration, and disinfection processes. Phosphorus will be removed by chemical precipitation in conjunction with the activated sludge and denitri- fication processes. Justification for project: The project is necessitated by rapid growth, -service area expansions, el imination of private and individual treatment devices, service agreements with neighboring cities. and higher imposed treatment standards; all in accordance with accepted regional plans. The project wil I further preclude the need to exp~nd or upgrade the existing Clearwater East. Dunedin and Safety Harbpr Treatment plants and will materially reduce the future pollutional loads which would otherwise be discharged to Old Tampa Bay and ~t. Joseph Sound.
