Recently, we proudly marked a major milestone for Monterey County with the ribbon-cutting for phase 2 of the Monterey One Water AWPF, the first full-scale potable reuse facility in Northern California. This indirect potable reuse project now supplies up to 7.6 million gallons of purified water daily, mitigating saltwater intrusion and drought vulnerability in the seaside aquifer. The project adds 2,250 acre-feet of water annually to the 3,500 acre-feet already produced and serves approximately 28,750 households.
This expansion positions the Monterey Peninsula as a leader in sustainable water management, with advanced purified water supplying more than half of the region’s demand. Addressing a decades-long crisis, this integrated solution sets a benchmark for water reuse throughout California. MWH provided Construction Management Services for the original, award winning, Monterey One Water APWF and Pump Station Project completed in 2020 and has continued these efforts for the expansion.

Congratulations to everyone who helped bring this visionary project to life and for joining us for the ribbon cutting:
The Bull Run Filtration Facility in Gresham, Oregon has earned the Envision Platinum Award, the highest honor from the Institute for Sustainable Infrastructure, recognizing its exceptional commitment to sustainability, environmental protection, and long‑term community benefit. As a major investment in the region’s drinking water system, the project will improve water quality, enhance reliability, and protect the Bull Run Watershed for future generations.
