The Town of Windsor, California is the pilot location of an innovative tarriffed on-water bill program based on the PAYS® (Pay As You Save®) system. The Sonoma Regional Climate Protection Agency has been assisting with the design and implementation of the Windsor Efficiency PAYS®. This pilot is the first demonstration of the PAYS® system at a municipal water utility and focuses on both energy and water efficiency improvements. Once the upgrades are installed, the participants pay a surcharge on their water bill aware that the upgrade savings will exceed the surcharge. The goal for the first year of the pilot is to engage 2,000 customers, which is approximately 4 times the number that the town's programs have reached over the past 5 years.
