Metropolitan Wastewater Management Commission Capital Improvement Program <br /> <br />PEAK FLOW MANAGEMENT IMPROVEMENTS <br />Description: <br /> The Peak Flow Management project combines several project elements described in the <br />2004 Facilities Plan into one project. These are 1) the Parallel Primary/Secondary Treatment <br />project, 2) the Bankside Outfall project, 3) the Outfall Mixing Zone Study, and 4) the design <br />and construction of the high rate disinfection basins, which was pulled out of the Sodium <br />Hypochlorite Conversion project and added to the Peak Flow Management project. These <br />project elements combine to provide the hydraulic infrastructure necessary to convey the <br />peak flow through the plant, split the flow into the parallel primary and secondary treatment <br />trains, provide additional disinfection capacity, and discharge the treated flow in accordance <br />with the 2004 MWMC Facilities Plan. <br />Status: <br />Construction completed. The remaining budgeted money will help fund the Water Pollution <br />Control Facility (WPCF) landscape project related to the MWMC Conditional Use Permit <br />(CUP) requirements. <br />Justification: <br /> This project expands the peak wet weather treatment capacity to 277 mgd through flow <br />management techniques. <br />Project Driver: <br />DEQ and Oregon Administrative Rules (OAR) related to winter peak wet weather flow (5- <br />year, 24-hour rain event). <br />Project Trigger: <br />Elimination of sanitary sewer overflows by January 1, 2010 related to OAR. <br />Project Type: <br />100% Capacity <br />Improvement SDC Eligibility: <br /> 30.2% <br />Estimated Project Cost <br />: $19,054,000 (part of the project money will support the treatment plant landscape <br />upgrades). <br />Expected Cash Flow: <br />FY 06-07 = $28,913; FY 07-08 = $1,499,833; FY 08-09 = $9,525,527; <br />FY 09-10 = $5,934,957; FY 10-11 = $788,770; FY 11-12 = $570,000; FY 12-13 = <br />$706,000 <br />2010-11 <br />Expenditure/Category:Prior YearsEst.
