Baffle, add inlet energy <br />dissipation, change out flocculation well, construct outboard launder. and retrofit suction <br />header for existing 8 secondary clarifiers. Construct 9th and 10th secondary clarifiers. <br /> <br />Enhancing the existing clarifiers will increase primary and secondary treatment capacity <br />and will maximize the facilities investment in existing infrastructure. Adding the 2 new <br />clarifiers will increase secondary treatment capability and increase ability to handle peak <br />flows. <br /> <br />Increase capacity to treat base and peak flows and improve effluent quality and reliability so <br />that a blended primary and secondary effluent can meet the current NPDES total <br />suspended solids limits. <br /> <br />Primary clarifier surface overflow rates exceeding 1500 gpd/sf, or total plant influent flows <br />exceeding 86 mgd. Hydraulic restrictions removed when peak wet weather flows exceed <br />200 mgd. Average secondary clarifier surface overflow rates exceeding 750 gpd/sf or wet <br />season maximum month flows exceeding 80 mgd. Wet season flows through secondary <br />treatment exceeding 134 mgd. <br /> <br />Capacity and performance <br /> <br />$12,800,000 <br /> <br />$17,480,000 <br /> <br />Originally budgeted in FY 2004/05 and unspent amounts carried forward to FY 06/07 <br /> <br />Page 67 <br /> <br />FY 06-07 BUDGET AND CIP <br />
