Water Supply Update

Water supply in local drinking water reservoirs, Lake Mendocino and Lake Sonoma, has recovered after reaching historically low levels following three years of severe drought. 

Now that the reservoirs are full, Santa Rosa City Council rescinded the city’s water shortage emergency on March 14, 2023. The water shortage emergency had been in place since June 29, 2021 and included a 20% communitywide reduction and restrictions on water use. 

Although there is no longer a local water shortage emergency, Santa Rosa will still need to comply with the city’s water waste ordinance and all existing statewide emergency water conservation regulations adopted by the State Water Resources Control Board. (See below for additional details)

Santa Rosa Water is thankful to our community for working together to achieve water savings during this water shortage emergency and for your continued efforts to be WaterSmart. To combat the drought, Santa Rosans reduced water use by 18% and saved 1.8 billion gallons of water.

Water Restrictions Header

All current restrictions are listed below. Previous drought prohibitions, including on powerwashing, are no longer active.

WAter Waste

Water waste due to breaks, leaks,  and excess use is prohibited. 

  • This includes leaking faucets, toilets, and appliances, as well as broken irrigation pipes, leaking irrigation valves, and broken sprinkler heads, and runoff from properties due to overwatering or mis-directed sprinklers.
  • Report Water Waste
brown lawn

Commercial, industrial, institutional non-functional turf must not be watered. Exceptions apply.

  • Effective June 10, 2022, commercial, industrial, and institutional (CII) non-functional turf must not be irrigated in California pursuant to recently adopted State Water Resources Control Board (State Water Board) regulations. Homeowners Associations’ common areas, unless it meets one of the other exemptions listed below, are included in this turf irrigation ban. 
  • The State has defined non-functional turf as, “Turf that is solely ornamental and not regularly used for human recreational purposes or for civic or community events.”
  • The State Water Board’s regulation states that some turf areas are exempt from the turf irrigation ban. The CII turf may still be watered after June 10, 2022 if the property owner or account holder determines that one or more of the following is true:
    1. The turf is used for human recreation, civic purposes, sports or play.
    2. The turf is irrigated with recycled water.
    3. The turf is irrigated with non-potable water (water that is not permitted for use as a drinking water supply).
    4. The turf is on the same valve as at least one tree or perennial non-turf plantings.
    5. The turf is owned by a resident or within an apartment complex, not at a commercial, industrial, or institutional location. The exception to this is common areas in Homeowners Associations sites. Unless one of the above exemptions applies, HOA common areas are included in this turf irrigation ban.
  • This emergency regulation adopted under Water Code section 1058.5 may remain in effect for up to one year, unless rescinded earlier, or extended by the State Water Board.
  • Please go to the State Water Board’s Water Conservation Emergency Regulations webpage for more information: bit.ly/conservationreg.
