Machesney Park, Illinois – The City of Broken Arrow’s only existing water treatment plant, erected in 1966, could no longer satisfy the needs of the 35,000 homes and businesses, requiring the City to purchase water from other facilities and nearby Tulsa. In cooperation with the Oklahoma Department of Environmental Quality and the Oklahoma Water Resources Board, a new municipal water treatment plant on the shore of the Verdigris River will provide up to 20 MGD (plant rating at 20 degrees C) of water daily to the City of Broken Arrow, Oklahoma. The project began in early 2012 with the bid for the standby power system awarded to Cummins Southern Plains LLC, Tulsa, for the parent company based in Arlington, Texas. The project will utilize three 2 MW generators powered by Tier II emission certified Cummins 16 cylinder QSK 60 series diesel engines. Due to the environmental and acoustic specifications of the water treatment facility, special enclosures and fuel tanks for the generator sets were required. Cummins Southern Plains LLC sales representative Mike Teague asked Hennig Enclosure Systems (Machesney Park, Illinois) to provide a possible solution.
As Mike explained, “Al Grabowski from Hennig had been in contact with Cummins Southern Plains. We gave him the opportunity to quote the project and were quite pleased with the results.” Cummins Southern Plains LLC provided the performance characteristics of the generator sets to Hennig Enclosures Systems, who then provided submittal drawings of the enclosure packages in Solid Works CAD format for the customer to review. Each enclosure measured 40′ long x 10′ wide and nearly 14′ high to allow ample airflow and provide a 25 dba sound reduction. After the customer and contractor approved the drawings, Hennig Enclosure Systems began cutting and bending steel.
