It is a privilege to earn this important recognition, and we are proud to help support our customers as they make conservation a way of life.
Congratulations to California Water Service on earning platinum-level recognition for implementation of the American Water Works Association G480 Water Conservation and Efficiency Program Standard 🎉🏅 We were proud to recognize the Cal Water team last week at California Water Efficiency Partnership's Peer to Peer Conference in Napa. As the first AWE member to achieve this recognition under the newly updated AWWA G480-25 standard, Cal Water is helping demonstrate what a comprehensive, data-driven water efficiency program can look like in practice. The G480 standard offers a practical roadmap for utilities committed to conservation excellence from system operations to customer engagement and education. Interested in learning more about the certification process and how your utility can get involved? Reach out to research@a4we.org.
