 Screw Pump Rehabilitation and Southside Flow Meter Project:
The Wastewater Treatment Facility has two- (2) wastewater screw pumps located at the head works of the Facility. The purpose of the pumps is to lift all of the incoming wastewater into the Facility for treatment. The pumps are rated at 18 million gallons a day each (MGD), they are 75′ long, 9′ in diameter and raise the raw sewage 40′. When the pumps were installed in 2002 they were the longest screw pumps in North America.  The pumps are made from steel and are coated to protect the metal. The pumps run 7/24/365 a year and are in a very harsh environment, which requires them to be recoated every 8 to 10 years.
The scope of the project included; Screw Pump sand blast and painting, influent channel cleaning, slide gate repair, slide gate actuator installation, Southside flow meter installation, lower bearing assembly replacement, deflecting plate replacement, upper bearing and coupling inspection, bypass pumping.
