Traditionally, utility water systems are installed below ground to allow the pumps to operate on a flooded suction. To reduce installation costs and make the equipment easily accessible for inspection and maintenance, Gorman-Rupp utility water systems for WWTPs are installed above ground.

Envirep recently started a utility water system at a Maryland wastewater treatment plant. The pumps were Gorman-Rupp Model 04A20-B self-priming centrifugal pumps. The system pumps plant effluent water into a pressurized piping system that distributes the water throughout the WWTP to maintain a constant pressure over a wide range of flows. The pumps will deliver up to 1,200 GPM and maintain a pressure of 125 PSI using a variable frequency drive.

The utility water system draws water from the treated plant effluent downstream of the chlorine contact tank to provide disinfected water for yard hydrants, spray water, foam control, a biofilter odor control system, and other uses throughout the WWTP.

The utility water pumps were installed as part of the plant upgrade project to meet Enhanced Nutrient Removal (ENR) requirements.

Supplied as a Complete Package

Gorman-Rupp utility water systems for WWTPs are supplied with pumps, motors, discharge header piping, and control panel. They are fully integrated and factory-built on a common fabricated steel base for easy installation. Systems can be provided with variable frequency drives and hydropneumatic tanks as the application requires preventing short cycling of the motors and maintaining constant pressure in the distribution system. Manual or automatic filters can also be provided.

The UL-labeled control panel has a stainless steel enclosure, circuit breakers, Allen Bradley VFDs, a programmable logic controller, elapsed time meters, indicating lights, discharge pressure transducer, and alarms.
