Water Conservation and Production Reports

Description / purpose

Since June 2014, the State Water Board has been tracking water conservation for each of the state's 409 larger urban water suppliers (those with more than 3,000 connections) on a monthly basis with a goal of documenting the reduction in water use. Water "production" is defined as urban water deliveries to customers. Conservation is calculated over time by reduced deliveries. The program has not been mandatory since 2017. However, many of the urban suppliers have continued to report on a voluntary basis. There is an effort to consolidate and streamline reporting under AB 1668 and SB 606 that will likely replace this system of reporting.
