The Wastewater Facility has four 266 horse power Raw Water pumps that bring
the wastewater into the Wet Weather Facility. During a large rain event, three
pumps are needed to pull a full 60 MGD through the Wet Weather Facility.
In October of 2020, the first of the four pumps failed. We had that rebuilt and
reinstalled. Since then, two additional pumps have failed. We had one of the two
newly failed pumps picked up and brought back to Williamson Pump & Motor for
inspection. They took the pump apart, inspected it, and determined what repairs
are necessary. They have provided us with a quote for labor and parts of
$50,072.15. With Williamson Pump & Motor having completed the inspection
and already having the motor in their shop opened up, we are recommending them
for a continuation of service.
