As a member of the Metropolitan Water District of Southern California (MWD), the Agency is the supplemental water provider for western San Bernardino County. Approximately 30% of the water used in the region is imported from the State Water Project through MWD.
Since 2009, imported water deliveries from northern California declined from a high of 78,872 acre-feet (AF) to 69,212 AF in 2017. In April 2017, Governor Brown declared the drought emergency over and with restrictions lifted, many areas throughout California have experienced varying levels of water-use rebound.
Within the IEUA region, a 10% increase occurred during fiscal year (FY) 2017/18, representing a rise in demand by 19,331 AF from FY 2016/17. Over the past nine years, the region’s population has grown by approximately 8%, however water use in the region is still 11% less than water use in FY 2013/14, which was during the drought.
Total water consumption in FY 2017/18 was 203,391 AF.
The region continues to work collaboratively on implementing cost-effective programs and projects that will diversify and maximize local resource development while expanding water-use efficiency programs. These efforts aim to prepare the service area for future dry years and increase regional resiliency in the face of new State regulations and climate change.
