Village Upgrades Sanitary Collection System with Four Hydromatic S8L-150HP Submersible Sewage Pumps

29.10.2001

ASHLAND, Ohio -- In anticipation of future growth, the Village of Romeoville, in conjunction with Robinson Engineering, decided to rehabilitate an existing left station that would become an important piece of Romeoville’s sanitary collection system.

Metropolitan Industries was invited to become part of the design team at the onset of the project. Mark Rosebraugh, sales engineer, oversaw Metropolitan’s portion of the project.

“Our focus was to increase the capacity of the pumps and controls while minimizing space and ensuring system efficiency and reliability" Rosebraugh said.

The original station was operating at constant speed in a “batch” type of operation via float switches. It was originally sized to pump a peak capacity of approximately 1.5 million gallons per day with one pump in operation and one pump on standby at 38hp per pump. With the anticipation of growth in the village, this would not make the grade.

According to Russ Prekwas, chairman of Robinson Engineering, Metropolitan Industries supplied four Hydromatic S8L 150HP non-clog submersible sewage pumps. Three pumps provide capacity for peak flow and one unit is a standby to meet Illinois Environmental Protection Agency requirements. According to Rosebraugh, the project didn’t end with the addition of the new pumps.

Working in concert with the engineers from Robinson Engineering and Gaskill & Walton Construction, Metropolitan Industries employed a PLC-based quadraplex control system that included a complete motor control center, a variable frequency drive (VFD) for each pump, flow meter, submersible level transducer, and integration into the villages’ existing SCADA system.

Presently, the lift station expansion is complete and running which will allow Romeoville to service the anticipated future growth.
