-, Metropolitan Wastewater Management Commission Capital Improvements Program <br />Design work for secondary clarifiers is planned in 2005. Construction upgrades to the secondary <br />clarifiers will be done in a phased multi-year approach during the dry season from 2006 to 2007 <br />~ with performance testing. <br />` ' South Aeration Basin Improvements <br />_; <br />FY 05-06 Capital Budget =Design $590,000, Construct $6,913,000 <br />'! Expected cash flow: * FY 05=06 $7,503,000. <br />The MWMC NPDES wastewater discharge permit, issued by the DEQ in 2002, placed a limit on <br />the allowable dry weather (May 1st through October 31st) discharge of ammonia for the first time. <br />' In order to meet this limit, the 2004 MWMC Facilities Plan identifies these projects to increase the <br />dry weather aeration basin treatment capacity to 65 mgd with respect to ammonia (i.e., with <br />i nitrification) and increase the sustained (i.e., on a weekly basis) wet~weather treatment capacity to <br />~ '' ' 130 mgd. This project includes design and construction to add step feed processing, anoxic <br />,_ <br />' selectors, fine bubble diffusers, and removes hydraulic restrictions in both south and north basins <br />'' "'~ (effluent gates). It also includes future primary effluent flow control gates for both north and south <br />.~ <br />basins. Staff will be coordinating system improvements that relate to needed equipment <br />r lacement com orients and funding. <br />P <br />Design work is planned for 2005. The construction is planned for 2005 to 2006. <br />Construction Management Facilities <br />FY 05-06 Capital Budget = $50,000 <br />Expected cash flow: * FY OS-06 $50,000. <br />~ This project is necessary to provide on-site office facilities for project/construction management <br />I <br />~ staff at the WPCF overseeing the construction work. A project and staffing plan is being <br />j developed in 2005 to determine the type, size and location of these necessary facilities. <br />New Projects <br />The following projects address needs/projects identified in the WWFMP (2001) and the 2004 <br />MWMC Facilities Plan. <br />Influent Pumping- (Screw Pump Station Expansion or Alternative Solution) <br />FY 05-06 Capital Budget = $1,807,000 <br />~', ('; Expected cash flow: * FY OS-06 $452,000; FY 06-07 $903,000; FY 07-08 $452,000. <br />' Three or more, influent pumping alternatives/solutions will need to be evaluated by a consulting <br />firm during the MWMC pre-design phase of this project.
