The first step, which has been completed, was installation of run time meters in the existing Community Center and Uptown pump tank control panels, and replacement of the Warming House pump tank controls. • Since then, wastewater was been sampled and data was collected from the run-time meters daily to obtain the information needed for design of the equalization tank and aerobic pretreatment unit and the new uptown pump tank. The plans are now complete and ready for bidding. • Brian Malm from Bolton & Menk will be present at the Council meeting. The Wastewater Advisory Committee will also be briefed at its July l9, 2012 meeting. • The Uptown Master Plan estimated the cost of the equalization tank and aerobic pretreatment unit to be $73,209. The new uptown pump tank was estimated to cost $25,564. Recommendation: Staff recommends approval of the plans and specifications and advertisement for bids.
