Metropolitan Wastewater Management Commission Capital Improvement Program <br />LINE BIOSOLIDS LAGOONS – PHASE 4 <br />Description: <br /> Reline existing lagoons, Phase 4 at the Biosolids Management Facility (BMF). <br />Justification: <br /> Existing clay lagoon liners are reaching the end of the material’s useful life. A new synthetic <br />liner will be installed in the lagoons. In Phase 1 and 2, the liner material of choice was high <br />density polyethylene. In the Phase 1 project implementation, the contractor installed the main <br />components for a new dredge lateral movement system for all four lagoons, for improved <br />operational safety and efficiency. <br />Project Driver: <br />MWMC proactively desires to improve the safety of BMF staff, improve operational reliability of <br />the facultative lagoons, and ensure DEQ compliance related to groundwater protection. <br />Project Trigger: <br />Implement the phased work based on the 2005 work plan schedule provided from MWMC to <br />DEQ. Continue to monitor the effectiveness of the first and second phase of the lagoon lining <br />projects. MWMC anticipates rehabilitating all four existing lagoons and monitor the new liner <br />improvements. <br />Project Type: <br />100% Rehabilitation <br />Estimated Project Cost: <br />$3,300,000 <br />Expected Cash Flow: <br /> FY 11-12 = $100,000; FY 12-13 = $1,540,000; FY 13-14 $1,660,000 <br />2009-10 <br />PriorEst. <br />Expenditure/Category:YearsAct.2010-112011-122012-132013-142014-15Total <br />Design/Construction 000100,000 $3,200,000 00$3,300,000 <br />Other 00000000 <br />Total Cost $0$0$0$100,000 $3,200,000 $0$0$3,300,000 <br />Page 48 DRAFT FY 11-12 BUDGET AND CIP <br />
