SAN FRANCISCO, CA — The Associated General Contractors of California (AGC of California) presented Walsh Construction with a Constructor Award at the 2026 Installation & Awards Gala, recognizing the project team's efforts and delivery of the Hyperion Advanced Water Purification Facility (AWPF). The project won in the Utility Infrastructure $15 Million to $100 Million category.

As the first major step of the Pure Water initiative in Los Angeles, California, this 1.5 million gallons-per-day facility transforms wastewater recycling, advancing the city’s goal of 100 percent reuse from the Hyperion Water Reclamation Plant.

Delivered under Los Angeles Sanitation & Environment’s first progressive design-build contract, the Walsh Construction and Brown and Caldwell team overcame space constraints, utility challenges, and pandemic disruptions while maintaining the budget and safety. Innovative solutions, including stacked equipment designs and early procurement of critical systems, ensured seamless integration within the constrained site. With $7 million in value engineering savings, zero OSHA recordable incidents, and a focus on community impact, the AWPF offsets potable water demand and supports workforce development.
