California is experiencing climate shifts that bring more extreme weather, resulting in a massive swing of our driest three years on record moving into some of the wettest precipitation patterns in recent history. Despite these swings, we must come together to continue to make conservation a California way of life. The California Public Utilities Commission (CPUC) is actively responding to current hydrologic conditions and working through this current year.

According to the United States Drought Monitor, the map for California is shown below:

Calling on Investor-Owned Utilities to Encourage Voluntary Conservation: The Commission is calling on the Investor-Owned Utilities (IOUs) to make all Californians aware of dry conditions and encourage actions to reduce water usage. (July 8, 2021 - Letter hereJune 9, 2021 - Press Release hereJune 8, 2021 - Letter here)

Drought Advice Letters

Participating in the Interagency Drought Team: Commission staff serve as members of the Governor's Office interagency drought team. This team will track changing conditions, coordinate state agency responses, and work closely with partners across the state.

Lessons Learned from the 2014-2015 Drought: The Water Division will remind the IOUs of best practices learned from the 2014-15 drought and potential actions and guidance for the IOUs to act on.

  • Messaging to ratepayers: Potential actions for the IOUs include notifying customers of voluntary conservation measures through a bill insert, direct mailing, social media, or other communication channels.
  • Encouraging voluntary conservation These voluntary conservation measures are outlined in Water Division's Standard Practice U-40 adopted previously in 2014 and reflect guidance on non-essential potable water usage. 

Save Our Water Campaign: The Water Division will enhance communication efforts to promote water conservation by updating the drought and conservation portion of its website, elevating the Save Our Water campaign and updating links to sister agency websites.

Coordinating with Other State Agencies: The Water Division will coordinate with the Department of Water Resources, the State Water Resources Control Board, and other sister agencies on conservation messaging and ongoing dry conditions across the state.
