As part of a large water system project, RETTEW provided services for two pumping facilities, with 20 miles of buried pipeline between them. The Ben’s Run Pumping Station withdraws water from the Ohio River via a submerged intake screen and intake pipe. The water is then collected in a wet well and pumped through 20- to 24-inch mixed material transmission pipeline to the Annie Booster Pumping Station. The project included extensive investigation, permitting, and engineering design services.
The Ben’s Run Pumping Station is capable of moving 80 barrels of water per minute, or 3,360 gallons per minute, at a discharge pressure of 434 pounds per square inch. The pumping station features four 400-horsepower vertical turbine pumps and telemetry controls. The transmission pipeline is equipped with a pig launcher and receiver to allow for proper maintenance of the asset. RETTEW designed the pipeline with mixed materials (i.e., steel and varying grades of (high density polyethylene) HDPE pipe) to achieve proper pressure ratings in the challenging West Virginia topography and to economize the project. We paid close attention to interior pipe diameters through the design process to ensure we could achieve uniform cleaning with a reusable pig.
