PLAYA DEL REY, Calif. — City of Los Angeles leaders gathered to commemorate the ribbon cutting of the Hyperion Advanced Water Purification Facility (AWPF) on April 1, 2026, celebrating a major milestone for the Pure Water Los Angeles program. Developed through a partnership and jointly financed between the City’s LA Sanitation & Environment (LASAN) and the Los Angeles Department of Water and Power (LADWP), the Hyperion AWPF produces up to 1.5 million gallons per day of highly purified water from recycled wastewater, offsetting potable water use at Los Angeles International Airport (LAX) and the Hyperion Water Reclamation Plant (WRP).

The Hyperion AWPF represents an investment in water security, sustainability, and environmental protection. By transforming recycled wastewater into a valuable resource, the facility will help the City become more resilient to climate variability and reduce reliance on imported water supplies. Located at the City of Los Angeles’ Hyperion WRP, the Hyperion AWPF is considered a “proof of concept” for the full transformation of the Hyperion WRP to a 100 percent water recycling facility as part of the Pure Water Los Angeles program—contributing to water security for millions of residents and improving the water quality of the Santa Monica Bay.

“The Hyperion AWPF is a consequential facility that demonstrates LA’s pathway to a reliable water future. We are proud to say that we had a part in starting this monumental journey to water independence.” —Steve Hirai, BC Vice President

Attendees included City of Los Angeles Councilwoman Traci Park, District 11; Nancy Sutley, Deputy Mayor for Energy and Sustainability; Steve Kang, President Commissioner of the Board of Public Works; Traci Minamide, LASAN Interim Director and General Manager; Nurit Katz, Vice President of the LADWP Board of Commissioners; Anselmo Collins, COO and Senior Assistant General Manager; Alfred Mata, Bureau of Engineering Interim City Engineer; and Crystal Lee, LAWA Deputy Executive Director—along with Tracy Quinn, President and CEO of Heal the Bay, representatives from LASAN, LADWP, the State Water Resources Control Board, and key members of the Walsh Construction–Brown and Caldwell progressive design-build team. City leaders and project partners celebrated the ribbon cutting as a visible step forward in delivering Pure Water Los Angeles—an initiative focused on long‑term water reliability, environmental stewardship, and public education about water conservation and reuse. 

“As we transform Hyperion WRP into an advanced water purification facility, recycled water allows us to eliminate pollutants that once reached Santa Monica Bay. It’s a critical step forward—for public health, for our water future, and for the environment.”—Huub Cox, LASAN Manager of Water Recycling Division

This was LASAN's first project using the progressive design-build delivery method, allowing collaboration to be center stage for LASAN, Walsh Construction, and Brown and Caldwell. The Hyperion AWPF is a one-of-a-kind, visitor‑friendly facility. The space blends aesthetic elements, including a multi‑purpose building that protects advanced treatment processes with a roof structure reminiscent of an ocean wave, outdoor terrace deck overlooking the Pacific Ocean, and a tranquil water feature showcasing purified water flowing directly from the plant. The facility also includes educational signage throughout to inform the public and students during tours, fostering support for water sustainability.

“This project shows what’s possible when teams collaborate deeply—from design to construction to commissioning—to deliver a facility that advances Pure Water Los Angeles and inspires a One Water future.” —Andrew Lazenby, BC Senior Director and Project Manager

The Hyperion AWPF project has received significant industry recognition for its delivery and technical approach, including the ENR Regional Best Projects 2025 Award of Merit in Water/Environment, the 2026 Associated General Contractors of California Constructor Award for Utility Infrastructure, and a 2026 WateReuse Association Excellence in Action Award for advancing the development of alternative water supplies through water recycling.
