Village Upgrades Sanitary Collection System with Four Hydromatic S8L-150HP Submersible Sewage Pumps |
ASHLAND, Ohio, June 27, 2001 -- 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. Hydromatic, founded in 1959,
is located in Ashland, Ohio, with additional distribution in Canada.
