Consolidated Water Wins $11.7 Million Contract to Build Wastewater Recycling Plant for San Francisco Bay Area Golf Club

GEORGE TOWN, Cayman Islands, Nov. 03, 2025 (GLOBE NEWSWIRE) -- . (NASDAQ Global Select Market: CWCO), a leading designer, builder and operator of advanced water supply and treatment plants, has been awarded a contract valued at $11.7 million to construct a wastewater recycling plant with 200,000 gallons-per-day capacity and 600,000 gallons of treated water storage for a San Francisco Bay Area golf club.

The contract was secured by the company’s California-based subsidiary, PERC Water Corporation, which develops, designs, builds, operates, and manages water infrastructure facilities in the Southwestern U.S. The plant will receive untreated wastewater diverted from a nearby sewer and will treat the wastewater using membrane bioreactor technology—a process that combines biological wastewater treatment with advanced filtration, resulting in high-quality recycled water suitable for irrigation. The innovative design incorporates key value-engineering features, most notably the substitution of precast concrete basins instead of cast-in-place concrete construction, as well as the use of prefabricated equipment buildings and platforms. These measures reduced construction costs and are expected to accelerate the overall project schedule.

By recycling wastewater for non-potable uses, the plant is expected to save 36 - 38 million gallons of potable water annually, reducing reliance on local freshwater resources. The project was designed by PACE Advanced Water Engineering, an engineering firm that has worked with PERC for over 25 years on numerous other projects.

Consolidated Water CEO, Rick McTaggart, commented: “This contract is the last of three design and/or build projects totaling more than $20 million that we expected to obtain in 2025 and mentioned in our investor calls earlier this year. Our competitive pricing, extensive permitting experience in California, and a fast-tracked construction schedule enabled us to offer a package that exceeded our customer’s expectations. The project is underway and is expected to be fully commissioned and operational by January 2027.”
