Metropolitan Wastewater Management Commission Capital Improvement Program Enhancing the existing clarifiers will increase primary treatment capacity, increase capacity to treat base and peak flows, and improve effluent quality and reliability so that a blended primary and secondary effluent can meet the current NPDES total suspended solids limits. Design and work on two clarifiers is planned for FY 04-05. Work on the remaining two primary clarifiers is planned for FY 05-06. Secondary Clarifier Enhancements FY 04-05 Capital Budget = $5,300,000 Expected cash flow: * FY 04-05 $1,300,000; FY 05-06 $2,700,000; FY 06-07 $1,300,000. This project is part of the overall MWMC Facilities Plan strategy to increase the peak flow treatment capacity. The project includes design and construction of baffling, inlet energy dissipation, changing out of the floccUlation well, construction of an outboard launder, and retrofitting of the suction header for the existing eight clarifiers. It also includes secondary gates. Enhancing the existing clariflers will increase the secondary treatment capacity, alleviate current operational problems, and will increase secondary treatment capacity for base and peak flows. Effluent quality and performance reliability will also be improved. These planned efficiency/ effectiveness improvements enable the deferral of the new secondary clarifiers originally planned for FY 04-05. Design and work on two clarifiers is planned for FY 04-05. Work on four clarifiers is planned for FY 05-06 with the final two clarifiers being completed in FY 06-07. South Aeration Basin Improvements FY 04-05 Capital Budget = $6,900,000 Expected cash flow: * FY 04-05 $1,725,000; FY 05-06 $5,175,000. The MWMC NPDES wastewater discharge permit, issued by the Department of Environmental Quality, in 2002, placed a limit on the allowable dry weather (May 1 st through October 31 st) discharge of ammonia for the first time. In order to meet this limit, the MWMC Facilities Plan identifies these projects to increase the dry weather aeration basin treatment capacity to 65 mgd with respect to ammonia (i.e., with nitrification) and increase the sustained (i.e., on a weekly basis) wet weather treatment capacity to 130 mgd. This project includes design and construction to add step feed processing, anoxic selectors, fine bubble diffusers, and remove hydraulic restrictions in' both south and north basins (effluent gates). It also includes future primary effluent flow control gates for both north and south basins. Design work and the beginning of construction is planned for FY 04-05. The remaining construction is planned for FY 05-06. Construction Management Facilities FY 04-05 Capital Budget = $100,000 This project is necessary to provide on-site office facilities for construction management staff at the WPCF during the 10-year MWMC facility construction effort. A project and staffing plan, to be developed in FY 04-05, will determine the type, size and location of these necessary facilities. · Cash Flow - In governmental budgeting, projects are fully budgeted in the fiscal year in which the contract is awarded. At the end of each fiscal year, unspent funds are carded forward until the project is completed. This April, 2004 DRAFT Page 28 FY 04-05 BUDGET AND CIP
