Emergency Intertie Test

Connecting Water Agencies and Ensuring Emergency Water Reliability

During major emergencies, municipal agencies work together closely to meet basic community needs, including access to safe and clean drinking water. At three strategic points throughout the DSRSD water system, DSRSD and East Bay Municipal Utility District (EBMUD) have established interties, or points of system interconnection, that allow for temporary exchange or delivery of water between the two water systems: two water supply interties are located on the northern DSRSD service area border, and a third water supply intertie is located in Dougherty Valley.

Starting October 24, 2023, DSRSD and EBMUD is testing the interties by transferring water between the two respective water systems. By deploying the personnel and infrastructure necessary to facilitate the water transfer, the emergency simulation will improve each agency’s abilities to respond to future emergencies and will ensure the proper operation of these temporary facilities. The test is anticipated to be finished in July 2024.

During this maintenance and test period, customers may notice slight differences in water quality and water pressure. To minimize the impact for residents, the testing will take place during regular business hours of 8 a.m. to 5 p.m., Monday through Friday.
