Consolidated Water Co. Ltd., a Cayman Islands–based company specializing in advanced water supply and treatment systems, has secured an $11.7 million contract to build a wastewater recycling plant for a golf club in the San Francisco Bay Area.

The project, awarded through Consolidated’s California subsidiary PERC Water Corporation, will include a 200,000-gallon-per-day treatment facility and 600,000 gallons of treated-water storage. The plant will divert untreated wastewater from a nearby sewer line, process it with membrane bioreactor (MBR) technology, and produce high-quality recycled water for irrigation use.

MBR systems integrate biological wastewater treatment with advanced membrane filtration, yielding effluent suitable for non-potable applications such as landscape irrigation, an increasingly important tool for drought-resilient water management across California.

To speed construction and reduce costs, PERC Water’s design incorporates precast concrete basins in place of conventional cast-in-place structures, along with prefabricated buildings and platforms for equipment. The company expects these measures to shorten the project schedule while maintaining durability and performance standards.

Once complete, the facility is projected to save between 36 million and 38 million gallons of potable water each year, easing pressure on local freshwater supplies.

The plant was designed by PACE Advanced Water Engineering, an Orange County-based engineering firm that has partnered with PERC Water on numerous water infrastructure projects over the past 25 years.

According to Consolidated Water’s announcement, the project is already underway and is expected to be fully commissioned and operational by January 2027.

The Bay Area project marks the final component of three design and build contracts totaling more than $20 million that the company expected to secure in 2025. Consolidated Water cited competitive pricing, California permitting experience, and a fast-tracked delivery plan as key factors in winning the contract.

The deal underscores a broader shift toward onsite water recycling and localized reuse systems in California’s commercial and recreational sectors, where the combination of persistent drought conditions and strict water-use mandates continues to drive investment in sustainable water technologies.

When complete, the new recycling plant will allow the golf club to meet nearly all of its irrigation needs without relying on municipal water, illustrating how infrastructure innovation and reuse can support both economic and environmental goals across water-stressed regions.
