Water Conservation


We have news about the City’s water supply as we hope for more winter rains: The last two winters have been exceptionally dry and as of February 1, 2021, Lake Sonoma storage is at 64% of water supply capacity and Lake Mendocino is at 41%.  Sonoma Water and the City of Rohnert Park are continuously monitoring the water supply conditions.  For more information about the impacts of low rainfall on our water supply, visit www.sonomawater.org/current-water-supply-levels

Although we encourage all water customers to implement everyday water saving practices both inside and outside your home or business as a way of life, we are asking customers to do more to reduce water-use due to the low amount of rainfall received this year.  Every drop saved by our customers helps improve water flows in the Russian River and extend reservoir storage levels should a longer dry period be experienced.  

 In the long run, even accounting for dry years, Rohnert Park’s water supply can meet the needs of our current residents and the growth we’re seeing with new housing.


The State and City both offer rebates to help residents save water. To download an application please click on the banners or links below or call 707-585-6750 for more information.
