I... ANALYSIS <br />The attached Work Authorization covers the redesign of the ' <br />Wastewater Treatment Plant primary treatment. This will be done and <br />bid as an alternate to the design originally proposed. The cost <br />associated with this alternate design is $13,800.00. It is <br />anticipated that the construction cost of the alternate will be <br />approximately the same as the engineer's proposed design but will <br />have reduced operating costs. The funds for the alternate design <br />will be charged to Account No. 472-000-169-006.00. <br />RECOMMENDATION <br />The staff of the Department of Utility Services recommends that the <br />Board of County Commissioners approve the attached Work <br />Authorizations for the North County alternate wastewater treatment <br />,plant design. <br />Director Pinto explained that the plant originally was <br />designed with screening devices to be after the surge tanks, with <br />the thought that they would put a large head screen system in the <br />2nd or 3rd phase, but Utilities engineering staff wanted to look <br />at the alternative to build screening ahead of the surge tanks <br />immediately and thereby eliminate a pumping device that would not <br />be needed under that design. This ultimately over the life span <br />of the facility would save the operating and replacement cost of <br />that pump and probably would result in saving about $20,000 a <br />year. <br />ON MOTION by Commissioner Scurlock, SECONDED by Com- <br />missioner Eggert, the Board unanimously approved Work <br />Authorization #WW -2 with Masteiler & Moler for redesign <br />of the Wastewater Treatment Plant primary treatment. <br />l �1 r <br />45 POR<a, <br />P1UG Ib 1999 <br />L <br />
