Carmel/Sorento Lift Station & Force Main

Due to imminent development in the Wilbarger Creek basin, the City of Pflugerville needed to address wastewater service. With one major wastewater treatment plant operating in a different drainage basin, options included pumping wastewater to the existing plant or constructing a new one in the Wilbarger basin.

During the recent Wastewater Master Plan update, the City chose to build the Carmel/Sorento Lift Station and Force Main (CSLS), allowing a 20-year delay in the construction of a future wastewater treatment plant. The CSLS, designed to receive wastewater flows from completed interceptors, delivers wastewater through a force main to an existing 24-inch force main on Weiss Lane. Our team was retained to design and construct the CSLS, providing wastewater facilities for two proposed subdivisions in the extraterritorial jurisdiction. Services included preliminary engineering, final design, and bid and construction phase services, addressing lift station site selection, force main alignment analysis, and wet well and pump sizing. The completed CSLS now conveys wastewater flows in the Wilbarger Basin to the Central Wastewater Treatment Plant for treatment.
