Contech Engineered Solutions needed this pump station to pump medium flows of clean water from a Contech filtration system to a nearby treatment pond. This system was designed with 5 hp Ebara pumps in a duplex configuration. A precast concrete wet well includes a pedestrian rated hatch and safety grate for reliable fall protection. Valve “cans” were included in the design and supply of this system for an economical control valve option. The control panel was a UL listed device in an outdoor enclosure, including a pressure transducer control device for redundancy.

The construction of a new Home Depot required a large detention pond and a new pump station to handle stormwater from the commercial development. This economical pump station uses 7.5hp Ebara pumps in a duplex configuration to meet the required flow rates to empty the detention pond. Parallel force mains were included with valve cans to provide simple and inexpensive piping and control valves. This submersible system uses cost-effective precast concrete barrels and a monolithic base to construct strong and reliable sump.

An IMTT industrial storage facility needed this stormwater pump station to collect runoff and pump it to treatment onsite. The duplex submersible pumps were engineered to handle the expected medium flows of stormwater. The pumps also needed to handle water that could potentially carry oil or other industrial chemicals stored on the site. An above-grade valve assembly used ball valves and check valves that were vertically integrated for easy access. The pump station electrical controls were located on an existing wall in the water treatment area.

The expansion of a college campus required this stormwater pump station to handle medium flows of stormwater runoff. To meet the required pumping rate, 7.5 hp Ebara submersible centrifugal pumps were designed in a duplex configuration. This pumping system was designed with dual force mains and check valves integrated in the discharge piping to simplify the engineering for the system. Romtec Utilities provided the complete electrical engineering plans for the UL listed control panel. Floats for primary and backup liquid level-sensing were supplied to give the system added redundancy.

The US Army Corps of Engineers worked with Romtec Utilities to design this lift station to replace an existing septic system. The resulting package wastewater lift station met the high sewage flows of this publicly owned industrial complex. The submersible sewage pumps in a duplex configuration are explosion proof to meet the wet well space classification. An outdoor UL listed panel utilizes floats and a pressure transducer for intrinsically safe level controls. It also includes an autodialer for communications and a blower for odor control.
