The Walnut Hill Pump Station in the northwest Dallas, TX, neighborhood of Walnut Hill, has been in operation since 1949. The station delivers potable water to multiple areas throughout the region, including to homes and local businesses and serves nearly one-third of the city’s residents. Due to aging equipment and the need for facility upgrades, the City of Dallas Water Utilities (DWU) contracted with STV to serve as the engineer-of-record to replace the two original pump stations. This project marked the first time DWU used the design-build delivery method for a city water project, which helped save time and reduce costs.
STV designed a single, new in-line booster pumping facility with an increased capacity of 44 million gallons per day (MGD). Our team developed a unique side suction pump station that optimized space and relieved the surge pressure on the suction side. The firm also provided permitting, commissioning quality control and construction oversight services. Blending into the neighborhood with an architecturally congruent façade, the facility features noise mitigation elements and was designed with Dallas “green building” practices.
One project challenge the team navigated was that the existing pump station needed to stay in service throughout construction while the new station was installed, ensuring customers never lost water service. STV worked closely with the owner and contractor to develop a construction sequence plan to construct the new pump station and demolish the existing facility without loss of service.
