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.

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. This will provide increased reliability and improved water flow for the
water system. The workwas done in cooperation with the school district under the high
school parking lot rehabilitation project.
