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