Metropolitan Wastewater Management Commission Capital Improvement Program INFLUENT PUMPING IMPROVEMENTS AND HEADWORKS EXPANSION Description: This project provides influent pumping improvements and headworks expansion required to accommodate the 2025 peak wet weather flow of 277 mgd. Major components include: upgrades to the Willakenzie Pump Station, expansion of the headworks facilities with new screening and grit removal equipment, a new Influent Pump Station at the WPCF, improvements to the regional force main system at two off-site locations, and landscaping. Due to the time critical nature of this project, it was delivered using a Construction Manager/General Contractor (CM/GC) project delivery process. Status: Construction stage. The majority of the construction was completed in December 2009. The work remaining in FY 10-11 is landscaping. Justification: Improved influent pumping and headworks hydraulic capacity are required to increase total plant influent hydraulic capacity to 277 mgd (the forecasted 2025 peak flow) and to meet redundancy requirements for pumping and screening. Project Driver: Ability to provide treatment to peak flows and systematic elimination of sanitary sewer overflows by the year 2010. Project Trigger: Collection system computer model estimates the current wet weather peak flow to plant to be 264 mgd. Overall existing peak flow capacity is 175 mgd so there is already a capacity deficit. Project Type: 100% Capacity Improvement SDC Eligibility: 38% Estimated Project Cost : $28,054,000 Expected Cash Flow: FY 05-06 = $16,348;FY 06-07 = $376,293; FY 07-08 = $2,132,064;FY 08-09 = $9,644,009; FY 09-10 = 15,758,000; FY 10-11 = $127,286 Expenditure/Category:Prior Years2009-10 Est.
