Gorman-Rupp offers an innovative approach to utility water systems for wastewater treatment plants (WWTPs) by installing them above ground. This contrasts with the traditional method of below-ground placement, which relies on flooded suction for pump operation. The above-ground design from Gorman-Rupp significantly reduces installation costs and enhances accessibility for routine inspection and maintenance.

A recent example of this is Envirep’s installation of a utility water system at a Maryland WWTP. This system utilizes Gorman-Rupp Model 04A20-B self-priming centrifugal pumps to draw treated plant effluent. The pumps feed this water into a pressurized piping network that serves various needs across the WWTP, including yard hydrants, spray water, foam control, and odor control.

Equipped with a variable frequency drive, the system is designed to deliver up to 1,200 GPM while maintaining a consistent pressure of 125 PSI across a wide range of flow demands. The installation of the utility water system was part of an upgrade project to meet Enhanced Nutrient Removal (ENR) requirements.

Supplied as a Complete Package

Gorman-Rupp delivers comprehensive utility water systems for WWTPs, providing a complete package that includes pumps, motors, discharge header piping, and a pre-wired control panel. To streamline installation, these components are fully integrated and mounted on a common fabricated steel base.

Depending on the specific application requirements, systems can be equipped with variable frequency drives (VFDs) and hydropneumatic tanks. VFDs optimize the pump and motor operation, while the hydro-pneumatic tanks prevent motor short cycling and ensure consistent pressure throughout the water distribution network. Furthermore, Gorman-Rupp offers the option of integrating manual or automatic filters to maintain water quality.

The UL-labeled control panel is housed in a durable stainless steel enclosure and features essential components such as:

  • Circuit breakers
  • Allen Bradley VFDs
  • Programmable logic controller (PLC)
  • Elapsed time meters
  • Indicator lights for system status
  • Discharge pressure transducer
  • Alarms
