The Clardy Fox pump station has a rated flow capacity of 665 cubic feet per second — 300,000 gallons per minute — or in other words, about an 8.5-foot-deep swimming pool the size of a college basketball court moved per minute. It included approximately 4,000 linear feet of channel shaping and lining and approximately 3,700 linear feet of storm sewer conduit and associated inlets.
The storm sewer conduits ranged from 42-inch diameter pipe to 120-inch diameter pipe and concrete boxes of varying sizes. Additionally, there were five road crossings with culverts involved in the channel work. These crossings involved the construction of box culverts and some unique headwalls in order to remain within the designated right-of-way. Hydrologic and hydraulic computer modeling of the storm sewer, culverts, and channel were performed using THYSYS and WSP-2.
Parkhill coordinated with the City of El Paso as the project owner, the Texas Department of Transportation (TxDOT), the Bureau of Reclamation, and the International Boundary and Water Commission (IBWC) during the project. The pump station and much of the storm sewer were situated on TxDOT right-of-way, a future Bureau of Reclamation irrigation canal right-of-way was crossed by the pump station’s 120-inch diameter discharge pipeline, and this same discharge pipeline had to penetrate the IBWC’s river flood control levees. Therefore, all of these entities were involved in the review and approval of the project.
