Equipment Upgrades Bring Pump Station Efficient Operation

In addition to the equipment we supplied to the Joe Orr Road Lift Stations of Chicago Heights, Ill., Metropolitan was also chosen to supply equipment to the 71st Street Stormwater Pump Station in Bridgeview, Ill.  The control and power distribution equipment was housed in a prefabricated concrete building with outside dimensions of 10’6” in length and 10’4” in width.

The addition of variable frequency drives will provide the pump station with efficient operation, which will lead to energy savings for the customer.

 
Three Hydromatic model S12L4000 non-clog pumps with 100’ cords and silicon carbide seals were supplied.  Each pump has a capacity of 3142 GPM at 29.2’ TDH for a total pumping capacity of 9,426 GPM when operating in parallel.  Each motor is rated at 40 HP, 1150 RPM, 460 volts, 60 Hz and three phase.  A 125 kW natural gas, sound attenuated Caterpillar generator was also included in the equipment package.

Metropolitan’s Keith Girup said Metropolitan was contacted to take part in the project at its inception, and that the eventual place where the building would be placed and function had much to do with its overall design.

“This pump station is on the southwest side of Toyota Park on 71st Street in Bridgeview where an IDOT viaduct is being constructed so that traffic can flow under the railroad tracks,” said Girup.  “The pumps will displace stormwater during rain events to prevent the viaduct from flooding.”

Girup said additions of variable frequency drives and enhanced controls with SCADA components will provide the municipality with both energy efficient operation and alarm notification if procedure encounters a malfunction.

Control upgrades were made at Metropolitan and the building was shipped fully assembled and ready for installation.

 
“This station has been designed with variable frequency drives which will vary the speed of the pumps to match the rainfall event,” said Girup.  “By varying the speed of the pumps, the motors will only consume the amps needed to match the influent rate, thus saving on electrical costs.”
