1.0 SCOPE

The contractor shall troubleshoot/diagnose, repair well, reinstall removed equipment, adjust/set well pump and motor, test, disinfect and monitor Well #20(building 20437). The contractor shall provide all services required to repair Well #20. The contractor shall provide all personnel, equipment, tools, materials, supervision, and other items and services necessary to affect the repair.

1.1 History/Background

Well #20 was constructed in 2007 and has been in operation since July 2008. Well #20 is estimated to have approximately 19,143 hours based on water production design rate of 1,400 gallons per minute (actual 1550 gpm). The motor on Well #20 had some burned up windings and was replaced on October 15, 2013. The breaker on the Motor Control Center was open and the well failed to operate. Maintenance crews discovered the issue and tried to restart the motor in manual operation. The motor did not start and it was noticed by maintenance crews that there were pieces of copper at the bottom of the motor. The damaged motor was replaced. The new motor was set in place and preliminarily adjusted by setting the nut at the top to the same place as the damaged motor. The new motor was operated in bypass and the electrical connections checked to verify rotation and balance. There was no indication by checking voltage/amps that the motor was overloaded. There was noise noticed when the pump was shut down after testing.

The pump was adjusted and there is still noise from an unknown source that appears to be coming from an area lower than the motor and pump head. The pump appears to be bound up and will not rotate manually.

1.2 Applicable Codes/Regulations
