<br />Description: This project provides influent pumping improvements and headworks expansion required to accommodate
<br /> the 2025 peak wet weather flow of 277 mgd. The scope and budget of this project incorporates the
<br /> following three (3) projects previously described in the FY 06/07 CIP budget report: Willakenzie Pump
<br /> Station Expansion, Influent Pumping Improvements, and Dry Weather Headworks. The budget for this
<br /> project includes $360,000 from the Equipment Replacement Reserve for the replacement of Equipment
<br /> #'s 15884 through 15889 (Pressure Line Gates) and newly included in the FY 07-08 budget, it includes
<br /> $45,000 from the Equipment Replacement Reserve for replacing 2 fans for the biofilter odor control
<br /> system and $12,000 from Major Rehabilitation Reserves for the replacement of two grit channel metal
<br /> rails. The project Includes landscaping and screening around the new construction area.
<br />Status: The RFP for preliminary design was issued August, 2006, Proposals were evaluated and consultant for
<br /> preliminary design (up to 30%) was selected in November, 2006, Commission approved negotiation of
<br /> preliminary design contract with selected firm on December 14th, 2006..
<br />Justification: Improved influent pumping and headworks hydraulic capacity are required to increase total plant influent
<br /> hydraulic capacity to 277 mgd. There are also outstanding issues regarding the redundancy requirement
<br /> for pumping which may affect the ultimate solution.
<br />Project Driver: Systematic elimination of sanitary sewer overFlows by the year 2010.
<br />Project Trigger: Collection system computer model estimates the current wet weather peak flow to plant to be 264 mgd.
<br /> Overall existing peak flow capacity is 175 mgd so there is already a capacity deficit
<br />Project Type: 100% Capacity
<br />Estimated Project Cost:. $27,715,000
<br />Expected Cash F low: FY 07-08 = $1,515,000, FY 08-09 = $25,166,652
