Hayden Bridge Optimization/Basin Baffling <br />The Hayden Bridge expansion study also investigated the configuration of filters, chemical feed systems, and basin <br />geometry. We believe EWEB can increase production by approximately 12 mgd by optimizing existing systems. <br />Pilot testing will be necessary to ensure proposed optimization measures will not reduce water quality. The <br />following is a cost estimate for optimization of Hayden Bridge. <br />EWEB Labor $ 21,000 SDC Funded $991,000 <br />Engineering $ 60,000 <br />Construction Contract $850,000 <br />Administration (-7%) 60 000 <br />Total $991,000 <br />Sludge Removal Bed <br />Add an additional drying bed near the sedimentation basins for sludge handling. <br />Engineering $ 30,000 SDC Funded $0 <br />Construction Contract $230,000 Rate Funded Capital $280,000 <br />Administration 20 000 <br />Total $280,000 <br />Water Division -Five-Year Capital Improvement Plan <br />11 <br />
