Cambrian and Anheuser-Busch Pioneer Water Reuse Model, Compete for Global Water Award

Cambrian, a wastewater treatment technology provider, and Anheuser-Busch have been named finalists for the 2025 Global Water Awards' Industrial Project of the Year, highlighting a transformative approach to industrial water management that could reshape sustainability practices across manufacturing sectors.

The project, centered at Anheuser-Busch's Houston brewery, introduces a novel Water-Energy Purchase Agreement (WEPA) model that enables large-scale water reuse without requiring significant capital investment from the brewery. By designing, financing, and operating a modular treatment system, Cambrian processes up to 400,000 gallons of high-strength wastewater daily, converting it into EPA-quality water for non-potable reuse.

Over the 20-year contract, the system is projected to treat 3.45 billion gallons of water while delivering substantial environmental and economic benefits. The project is expected to reduce water and wastewater costs by 20% and avoid more than 23,000 tons of carbon dioxide emissions, demonstrating a compelling case for sustainable infrastructure investment.

The innovative approach eliminates traditional barriers to water treatment infrastructure by removing capital expenditure risks and operational complexities. Cambrian finances, builds, owns, and operates the system, charging only for the volume of water treated. This model ensures operational excellence through on-site specialized personnel while providing Anheuser-Busch with a flexible, performance-driven solution.

Environmental impact extends beyond water conservation, with the project anticipated to eliminate 1,230 metric tons of CO₂ emissions annually—equivalent to removing over 260 cars from roadways. This achievement underscores the potential for industrial partnerships to drive meaningful sustainability transformations.

The collaboration originated through Anheuser-Busch's 100+ Accelerator, a global sustainability innovation platform, and leverages Cambrian's BlueCycle™ membrane bioreactor technology. By demonstrating that environmental sustainability can align with economic efficiency, the project represents a potential blueprint for industrial water management strategies worldwide.

The Global Water Awards, presented by Global Water Intelligence, will recognize the project at the upcoming Global Water Summit in Paris, France, celebrating significant achievements in international water industry innovation.
