When May 28 thecell phone antenna equipment is reinstalled on the tower, the project will be complete. We discoveredthat well number 5 had been draining water back into the aquifer when it was not running, causingair to be pushed into the water system each time it started pumping again. Thiscontributed to the air issues we experiencedin the watersystemin late February. E.H. Renner & Sons pulled the submersiblewell equipment and determined that the check valve had failed, and the pipe was in poor condition. They installed a new check valve and 160 feet of new pipe. The price for this work was quoted at $13,310. The Gary Street Water Tower has been taken out of service and drained for the rehabilitationproject that started June 1. The estimated completion date is July 24, 2020. ______________________________________________________________________________ Page 1 of 2 151 Approximately 600 feet of six-inch cast-iron water main pipe, formerly located between School Street and the new Multipurpose Facility, has been replaced with new eight-inch ductile-iron pipe.
