Metropolitan Wastewater Management Commission Capital Improvement Program PEAK FLOW MANAGEMENT IMPROVEMENTS Description: The Peak Flow Management project combines several project elements described in the 2004 Facilities Plan into one project. These are 1) the Parallel Primary/Secondary Treatment project, 2) the Bankside Outfall project, 3) the Outfall Mixing Zone Study, and 4) the design and construction of the high rate disinfection basins, which was pulled out of the Sodium Hypochlorite Conversion project and added to the Peak Flow Management project. These project elements combine to provide the hydraulic infrastructure necessary to convey the peak flow through the plant, split the flow into the parallel primary and secondary treatment trains, provide additional disinfection capacity, and discharge the treated flow in accordance with the 2004 Facilities Plan. Status: Construction stage. The majority of the construction was completed in December 2009. The work remaining in FY 10-11 is landscaping. Justification: This project expands the peak wet weather treatment capacity to 277 mgd through flow management techniques. Project Driver: DEQ requirement that the peak wet weather flow (5-year, 24-hour rain event) be treated by the E/S WPCF and meet secondary effluent standards (diverted blended flow receives equivalent of primary treatment). Project Trigger: Elimination of sanitary sewer overflows by the year 2010. Project Type: 100% Capacity Improvement SDC Eligibility: 30.2% Estimated Project Cost : $20,872,000 Expected Cash Flow: FY 06-07 = $28,913; FY 07-08 = $1,496,808; FY 08-09 = $11,346,006, FY 09-10 = $5,000,000; FY 10-11 = $2,992,843; FY 11-12 = $7,157 2009-10 Expenditure/Category:Prior YearsEst.
