Water Conservation is a Way of Life

The City recognizes the importance of making water conservation a way of life at all times. We partner with Valley Water and the Bay Area Water Supply and Conservation Agency (BAWSCA) to deliver rebates for water efficient landscaping upgrades as well as products and projects that conserve water and reduce storm water runoff. Visit our Save Energy & Water page to view available water efficiency resources. Learn more about the City's water supply by visiting our Water Resources page and reading the City's Annual Water Quality Report(PDF, 5MB).

Update on Current Water Conditions

California is experiencing dry weather conditions, and the Governor and the city’s water supplier, the San Francisco Public Utilities Commission (SFPUC), are asking Palo Altans to reduce water usage. On November 23, 2021, the SFPUC declared a water shortage emergency for the Regional Water System and adopted a 10% system-wide voluntary water use reduction goal.

Water waste in Palo Alto is prohibited. Read about the City's water use regulations in the municipal code.

Water FAQs

How are you enforcing the water use restrictions?

The current focus is on education and outreach including reminding customers about permanent water use restrictions and providing resources to achieve efficient water use. Many calls and emails come from residents who report runoff, leaks, or other observations of perceived water waste. The City offers a web and mobile application tool for reporting water waste through PaloAlto311. When we receive information about potential water waste, we attempt to contact the customer and use door hangers when we are unable to speak with the customer.

If the drought worsens, enforcement will increase. On September 15, 2014, Palo Alto City Council adopted a plan for responding to incidents of the water use restrictions and we are continuing to follow this enforcement plan.

  • 1st incident: Doorhanger/Email/Phone call to customer
  • 2nd incident: Doorhanger/Email/Phone call to customer
  • 3rd incident: Certified letter from the Utility Director notifying customer of violation and potential future fines
  • 4th incident: Fines ($500 per infraction, per day) (PAMC 12.20.010)
  • 5th incident or more: Flow restrictors may be installed

How does the Governor’s declaration affect Palo Alto?

Governor Newsom issued a Drought Executive Order on July 8th calling on all Californians to voluntarily reduce water usage by 15% compared to 2020 levels. There are no mandatory water use reductions in place. Palo Alto is responding appropriately to this and to the SPPUC’s water shortage emergency declaration with increased outreach and education to encourage wise water use across the city.

How is Palo Alto doing with respect to reducing water use?

The Palo Alto community reduced water usage by 10% for the period July 1 – November 30 in 2021, compared with the same periods in 2019. From billing data for the same months, residential customers reduced usage by 9% and non-residential customers reduced usage by 8%.

Is Palo Alto impacted by Valley Water’s emergency declaration?

Palo Alto does not receive water from Valley Water and is not directly impacted by Valley Water’s supply shortage. On June 9, the water supplier for most of Santa Clara County, Valley Water, declared a water shortage emergency and adopted a 15% mandatory water use reduction for water retailers its agency serves. While the drought is impacting the entire state, individual water systems are experiencing system-specific challenges.

What are some ways Palo Alto residents can conserve water?

Outdoor water use makes up the majority of a household's overall water consumption. Regularly checking for leaks and landscape water efficiency are great ways to conserve a large volume of water. We partner with Valley Water on a variety of outdoor water conservation programs that will help you conserve water outdoors.

Efficient indoor water use is important too. Be sure to regularly check for leaks and replace old toilets and clothes washers with new, efficient models. Valley Water provides low-flow showerheads, faucet aerators and automatic shut-off hose nozzles free of charge. Visit the Valley Water Shopping Cart online to request these items free of charge. CPAU’s Home Efficiency Genie is another great resource for tips on improving the efficiency of your home. Contact the Genie at (650) 713-3411 for a free over-the-phone consultation.

How can we protect our trees during the drought?

We want to remind people to continue irrigating trees during the drought. Trees represent high-value landscape that requires a long-term, significant investment. A healthy urban canopy offers many benefits to the community and environment. Visit Canopy's online Tree Library to pick drought resistant trees before planting. Canopy also provides watering instructions, tree care guides, and more.

How can businesses save water?

Businesses can participate in our water-saving programs and receive free installation of toilets, urinal flush valves, pre-rinse spray valves for dishwashing, low-flow faucet aerators, showerheads, and rebates for upgrading other appliances and equipment. Visit Valley Water’s rebates page to learn more about the resources available to businesses in Palo Alto.

How is the City planning for more water resiliency in the future?

The 2020 S/CAP update is underway, and a key action is to develop a plan for implementing a One Water portfolio. The One Water approach to integrated water resource planning will take a broader, more comprehensive look at water supply options including green stormwater infrastructure, recycled water and other non-potable water sources to supplement and preserve the potable water supply.

How can the community provide the City with feedback or ask questions?

City of Palo Alto staff are always interested in hearing from the community. Your feedback is welcome. Please feel free to share your comments, suggestions and/or questions with us at UtilitiesCommunications@cityofpaloalto.org Thank you for the opportunity to share information on this subject.

Remember, it is important to use water wisely every day, regardless of drought conditions. Thank you for doing your part to help Palo Alto meet its water efficiency goals!
