Palos Verdes Recycled Water Pipeline and Lago Seco Pump Station Design

Client: West Basin Municipal Water District
Our Role: Design and Construction Services

Booster pump station interior with vertical pumps, valves, and piping for recycled water distribution.

To support the West Basin Municipal Water District’s goal of expanding recycled water use for communities and parks in the Torrance area and the Palos Verdes Golf Club in Palos Verdes Estates, GFT provided design services during construction for the Palos Verdes recycled water pipeline and Lago Seco Pump Station. As demand for sustainable water sources grows, this infrastructure is expected to deliver nearly 80 million gallons of cleaned wastewater annually for irrigation, helping conserve drinking water and strengthen drought resilience. GFT led engineering and coordination across design and construction to ensure seamless integration with West Basin’s broader recycled water system.
