Metropolitan Wastewater Management Commission Capital Improvements Program Design work for secondary clarifiers is planned in 2005. Construction upgrades to the secondary clarifiers will be done in a phased multi-year approach during the dry season from 2006 to 2007 with performance testing. South Aeration Basin Improvements FY 05-06 Capital Budget = Design $590,000, Construct $6,913,000 Expected cash flow: * FY 05-06 $7,503,000. The MWMC NPDES wastewater discharge permit, issued by the DEQ 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 2004 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 removes 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. Staff will be coordinating system improvements that relate to needed equipment replacement components and funding. Design work is planned for 2005. The construction is planned for 2005 to 2006. Construction Management Facilities FY 05-06 Capital Budget = $50,000 Expected cash flow: * FY 05-06 $50,000. This project is necessary to provide on-site office facilities for project/construction management staff at the WPCF overseeing the construction work. A project and staffing plan is being developed in 2005 to determine the type, size and location of these necessary facilities. New Pro|ects: The following projects address needs/projects identified in the WWFMP (2001) and the 2004 MWMC Facilities Plan. Influent Pumping - (Screw Pump Station Expansion or Alternative Solution) FY 05-06 Capital Budget = $1,807,000 Expected cash flow: * FY 05-06 $452,000; FY 06-07 $903,000; FY 07-08 $452,000. Three or more influent pumping alternatives/solutions will need to be evaluated by a consulting firm during the MWMC pre-design phase of this project. The 2004 MWMC Facilities Plan anticipates upgrades to the screw pump station by adding a fifth pump to increase the capacity from 84 to 99 mgd. The total influent pumping capacity of all directly connected pump stations is estimated at 277 mgd for peak wet weather flow. DEQ pumping redundancy requirements will need to be reviewed by the,design consultant/team and MWMC as the project develops. This Review Draft April 21, 2005 Page 30 FY 05-06 BUDGET AND CIP
