EBMUD & DSRSD Emergency Intertie Test 2023

EBMUD DSRSD IntertieProject description

East Bay Municipal Utility District (EBMUD) and the Dublin San Ramon Services District (DSRSD) are working together to enhance our water systems and emergency response capabilities.

We will simulate an emergency scenario, testing our water transfer capabilities through specific connections between our systems. This helps us prepare for real emergencies and ensures that everything runs smoothly when needed.

In times of significant emergencies, we prioritize collaboration with fellow municipal agencies to ensure that we continue providing access to safe and clean drinking water. To fortify this commitment, we've strategically established three interties connecting the East Bay Municipal Utility District (EBMUD) and the Dublin San Ramon Services District (DSRSD). These interties serve as crucial points of system interconnection, enabling the temporary exchange and delivery of water between both districts. You can find two of these interties along the southern border of the EBMUD service area in San Ramon, with the third intertie located in San Ramon's Dougherty Valley. These connections are instrumental in safeguarding your access to high-quality water during times of need.

EBMUD and DSRSD are collaboratively conducting a vital intertie test, involving the controlled transfer of water between our two distinct water systems. This comprehensive emergency simulation not only fine-tunes our readiness but also enhances our response capabilities for potential future crises. It ensures the seamless operation of these temporary facilities while refining our coordination and processes. We expect to complete this essential test by mid-November. Your safety and the reliability of your water supply remain our top priorities.


Tests will begin on October 24, 2023, with an anticipated completion in Mid-November. These tests will only take place during weekdays, between 8 a.m. and 5 p.m.

What to Expect

During the testing hours, you might notice minor, temporary changes in water quality and pressure.

We appreciate your patience and support as we strive to improve the reliability and resilience of our water systems.
