Metropolitan Wastewater Management Commission Capital Improvement Program Plant Predesign Study and Facilities Plan (Formerly - Plant Performance Improvements - Predesign Study) FY 04-05 Capital Budget = $200,000 The predesign project evolved into a comprehensive Facilities Plan that establish RWP capital needs through the year 2025. During FY 03-04, the project scope was modified to include determining future use alternatives for the Seasonal Industrial Waste Facility, and to provide professional assistance with developing SDC methodology alternatives.' The $200,000 carried forward to the FY 04-05 budget will fund actual predesign studies for the projects identified in the Facilities Plan as phase one projects. Lab Modification FY 04-05 Capital Budget = $45,000 The Lab Modification project was essentially completed in FY 03-04. There are two remaining issues: (1) exhaust fan vibration isolation system problems; and (2) acid neutralization system problems that were identified during the later part of 2003. The funds carried forward to FY 04- 05 are intended to complete any remaining retrofits necessary for final resolution of any remaining operational difficulties with the new lab facilities. New Proiects: The following projects address needs/projects identified in the WWFMP (2001) and the 2004 MWMC Facilities Plan. Digester Mixing Improvements FY 04-05 Capital Budget = $2,000,000 Expected cash flow:* FY 04-05 $660,000; FY 05-06 $1,340,000. The 2004 Facilities Plan identifies the need to provide additional solids stabilization volume. This project includes design and construction of digester mixing improvements that will increase the active volume of the existing three digesters, thus allowing for additional solids stabilization volume. This will be accomplished by replacing the existing gas mixing system with a pump mixing system. This project will also defer the need to construct an additional digester. Design work and the beginning of construction is planned for FY 04-05. The remaining construction work is planned for FY 05-06. Primary Clarifier Enhancements FY 04-05 Capital Budget = $1,200,000 Expected cash flow:* FY 04-05 $600,000; FY 05-06 $600,000. The preferred alternative for treating peak flows in the 2004 Facilities Plan, is called Parallel Primary/Secondary Treatment. In this alternative, peak flows up to 130 million gallons per day (mgd) will receive primary treatment in the primary clarifiers and be diverted around the aeration basins and secondary clarifiers. Flows greater than 130 mgd will be treated in the aeration basins and secondary clarifiers. The two flows will be blended back together and receive chlorine disinfection before being discharged. The Primary Clarifier Enhancements project includes design and construction of baffling in the primary cladfiers and removal of hydraulic restrictions.
