Cost-Efficient Equipment Supplied to Pump Stations

At Metropolitan, we can supply all equipment needed to keep your pump station functioning as efficiently as possible.  Our adaptability and knowledge of new technologies give us the ability to supply the most cutting-edge equipment, which can extend the life of a system and save end users funds.  We recently supplied equipment to two pump stations with the end goal of bringing up to date, cost-efficient solutions to our customers.

Joe Orr Road Lift Stations – Chicago Heights, IL

Metropolitan was chosen to supply all equipment associated with the upgrade of the existing Stormwater and Sanitary Lift Stations for the Joe Orr Road Lift Stations of Chicago Heights, IL.  The new lift stations include a number of up to date accessories and were housed in a large pre-fabricated concrete building.

Metropolitan’s Bob Wedell said a number of factors contributed to the customer’s decision to make the upgrades.

“The project was done to replace an existing dry-pit type sanitary lift station that was over 30 years old,” said Wedell. “The design was chosen to eliminate the confined space environment as well as improve the operational efficiency, thus improving safety and reducing cost of daily operations.”

The Stormwater Lift Station contains two Hydromatic model S4N300 submersible non-clog pumps, each with a capacity of 150 GPM at 20’ TDH.  Each motor is rated at 3 HP, 1750 RPM, 230 volts and 60 Hz.  One submersible level controller and five level switches to control on, off, override and alarm levels were also provided with the Stormwater Station.

The Sanitary Lift Station contains two Hydromatic model S4MVX750 submersible non-clog vortex explosion pumps, each with a capacity of 375 GPM at 28.5’ TDH.  Each motor is rated at 7.5 HP, 1750 RPM, 230 volts, 60 Hz and are explosion proof at Class I, Division I, Group C and/or Group D locations.  One submersible level controller and five level switches to control on, off, override and alarm levels were also provided with the Sanitary Station.

The pre-fabricated concrete building measures at 20’ L x 8’ W x 9’ H (outside dimensions).  The building is comprised of a 36” x 84” single door for the control room and a 72” x 84” double door for the generator room.  A Caterpillar 55kW rated generator was also included.

Wedell said the way in which the total system operates makes the application distinctive and efficient.

“This project is unique because the controls and generator are capable of operating the sanitary lift station as well as the nearby storm water lift station,” said Wedell. “By discussing the options and costs associated with also upgrading the storm water lift station simultaneously with the sanitary lift station the owner and engineer were able to make an educated decision to upgrade both lift stations and reap the benefits of twice the improved technology more cost effectively.”

Wedell said Metropolitan’s involvement in the project can be attributed to a long standing relationship with the City of Chicago Heights and project engineer.

“Metropolitan has been a trusted partner for the owner and engineer for many years and we were contacted at this projects’ inception,” said Wedell. “We were instrumental in assisting with the design which included budget number preparation used for grant funding acquisition.”

Metropolitan was also chosen to supply equipment to the 71st Street Stormwater Pump Station in Bridgeview, IL.  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.

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 operation in parallel.  Each motor is rated at 40 HP, 1150 RPM, 460 volts, 60Hz and three phase.  A 125 kW natural gas, sound attenuated, Caterpillar generator was also included in the equipment package.

Wedell said Metropolitan was contacted to take part in the project at the project’s 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 Wedell.  “The pumps will displace stormwater during rain events to prevent the viaduct from flooding.”

Wedell 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.

“This station has been designed with variable frequency drives which will vary the speed of the pumps to match the rainfall event,” said Wedell.  “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.”
