Utica East Ohio Midstream needed two new pump stations to handle low flows of stormwater runoff at its new Kensington Plant in Ohio. To responsibly contain potentially hazardous stormwater from the topsoil, these pump stations were designed with double-wall fiberglass wet wells with interstitial leak detection. Both pumping systems included corrosion resistant components and sensors due to the potential presences of LNGs in the stormwater runoff. Pumps were engineered with 7.5 hp Ebara pumps in a duplex configuration, and different impellers were specified for each of the two pump stations meet slightly differing head requirements.

Utica East Ohio Midstream needed a new pump stations to handle low flows of stormwater runoff at its new Kensington Plant in Ohio. To responsibly contain potentially hazardous stormwater from the topsoil, this pump station was designed with a double-wall fiberglass wet well with interstitial leak detection. The pumping system also included corrosion resistant components and sensors due to the potential presences of LNGs in the stormwater runoff. Pumps were engineered with 7.5 hp Ebara pumps in a duplex configuration, and a UL listed control panel was supplied with added cable lengths for installation outside of NFPA classified spaces near the pump station.

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.

A new 144,000 square feet, two building industrial center needed a large stormwater pump station to handle the runoff from the site. This triplex system includes a fourth, “jockey” pump to handle low flow dry-season runoff. The three large pumps are 20 hp Ebara submersible pumps designed for redundant pumping during high flow events. A pressure transducer serves as the primary level-sensing device and operates inside of a perforated stilling well designed to prevent solids from interfering with the sensor. The electrical controls are configured with a logic relay, intrinsically safe circuits, and communications.
