en.Wedoany.com Reported - San Jose Water Company recently announced a direct potable reuse demonstration project that purifies recycled water into high-quality drinking water, aiming to assess its feasibility as a long-term water source. This proof-of-concept demonstration will test direct potable reuse technology to purify recycled water in compliance with California's direct potable reuse regulations.

The project includes the design and implementation of a mobile recycled water purification system, costing approximately $3 million. The mobile recycled water unit can be deployed throughout San Jose Water's entire service area to demonstrate recycled water performance and support community education. The company expects the recycled water demonstration system to be completed within two years, including time for testing and evaluation in accordance with state regulations. San Jose Water has engaged a design consultant to guide the initial phases of recycled water engineering and compliance, and is collaborating with agencies such as the San Francisco Public Utilities Commission and the South Bay Recycled Water Reclamation Company to share technical expertise.

Tanya Moniz-Witten, President of San Jose Water Company, stated: "Our goal is to test this new recycled water technology to see if it can serve as a reliable and affordable long-term recycled water source for our customers. Our mission is to provide affordable, reliable recycled water while putting customers first. Every recycled water infrastructure decision ultimately impacts customers' bills, so it is crucial to design efficiently and manage recycled water projects responsibly from the outset."

Community feedback and results from the recycled water demonstration project will inform the design and construction of a full-scale recycled water purification plant. Colorado approved the nation's first statewide direct potable reuse regulations for recycled water in November 2023, followed by California in October 2024, and Arizona passed relevant recycled water regulations in March 2025. San Jose Water Company, established in 1866, is a regulated private recycled water utility serving over one million people in the greater San Jose metropolitan area.
