The LeClaire Pump Station is a 6,400 sf. facility, which with four 600 HP pump motors, has the capability to pump over 41,600 gallons of water per minute as built. The building was designed to accept an additional two pumps, which would increase the discharge volume to up to 62,400 gallons per minute. The facility was built for the Village of Bedford Park who will use it to pump City of Chicago water to the south and southwest suburbs. The piping includes 54” flanged pieces inside the building, and over 500’ of restrained joint ductile iron pipe outside the building. The building is equipped with a 4,210 cubic inch, 2250 kW generator, which allows the facility to continue to operate under a power service failure. The building itself is constructed of ground face block walls situated on a cast in place concrete foundation. The roof is bow truss construction supported by an interior steel frame, and includes a structural roof covered by an aluminum standing seam roof. Also included in the building are a 10-ton overhead crane, a SCADA control room, a chlorine room, and truck bay.

The Upper Des Plaines Pumping Station Rehabilitation and TARP Connection project is scheduled in two phases. Phase 1 consists of constructing a new reinforced concrete diversion structure around an existing interceptor sewer. The work is entirely below ground and will be accomplished by excavating a 35’ diameter x 60’ deep vertical shaft. The diversion structure will house several large electrically actuated gates that can be opened and closed to divert the flow of wastewater to MWRD’s deep tunnel. A new 72” diameter reinforced concrete pipe will be installed to connect the diversion structure to an existing deep tunnel drop shaft. This work involves underground mining to create a horizontal shaft in which to install the new pipe and make all necessary connections.

Phase 2 consists of renovating the existing pump station and involves asbestos abatement, selective demolition, cast-in-place concrete, masonry restoration, carpentry, new windows and doors, plumbing, mechanical and electrical upgrades. A significant upgrade to the pump station will be the replacement of three 350HP centrifugal wastewater pumps and motors.

The sitework will consist of placing new asphalt paving, new concrete paving and landscaping, as well as construction of a new 75’x30’ biofilter that will rid foul sewer air of odorous gasses before being emitted into the atmosphere.

The Western Avenue Pump Station project consisted of the demolition of an existing boiler house and construction of a new addition to house a reused boiler from a previous FHPSNN project at the Roseland Pump Station. The masonry building was constructed around the existing boiler. The boiler installation included heavy mechanical and control coordination with the existing facility in order for this boiler to work in conjunction with the Department of Water Management's remaining boilers.

The Wheaton Pump Station project consisted of converting an existing pedestrian bridge to a vehicular bridge by driving piers, pouring abutments, and installing a precast sectional bridge in addition to miscellaneous pavement repairs and replacement. The project also included construction of a 600 sf. Septage/Leachate Receiving Station which holds a receptacle for septage and leachate that either goes to the sewers for future treatment or is collected and treated elsewhere.
