Tri-Valley Water Agencies Mandatory Water Usage Restrictions Remain in Effect

News Release

TRI-VALLEY, CA (November 10, 2021) - The Tri-Valley continues to battle unprecedented drought conditions despite October’s atmospheric river. While recent storms brought some much-needed relief, the overall drought situation remains bleak, and conservation is still needed.


However, the good news is that in October the Tri-Valley stepped-up their conservation efforts and exceeded the Tri-Valley’s 15% water savings goal. The Tri-Valley used 20% less water in October 2021 compared to October 2020. Water agencies are hopeful that the message continues to be received and residents continue their water-saving habits.


In September, Zone 7 Water Agency declared a Drought Emergency and Stage 2 Water Shortage Emergency. This declaration included mandatory 15% water conservation from all Tri-Valley water service providers, which are the Cities of Livermore and Pleasanton, Dublin San Ramon Services District (DSRSD), and California Water Service (Cal Water). In response to Zone 7 Water Agency’s Drought Emergency, the Tri-Valley’s water service providers have activated the mandatory water restrictions below.




  • Outdoor irrigation is limited to occur between 9 p.m. and 6 a.m. to reduce evaporation
  • Outdoor irrigation during and within 48 hours after measurable rainfall is prohibited
  • Outdoor irrigation is limited to no more than three non-consecutive days per week
  • From November 1 through February 28, outdoor irrigation is limited to one day per week
  • Customers must repair or stop water leaks upon discovery or within 24 hours notification by the District.
