City of Palo Alto Utilities Receives the Silicon Valley Water Conservation Award!

These awards recognize groups and individuals whose programs and leadership have advanced water conservation in Silicon Valley. Palo Alto is being recognized for having one of the most outstanding water efficiency programs in the State. The enthusiastic participation of our residents and businesses in our programs is the big reason for their success---so thank you all!

California's Water Conditions

In many areas of California, the year 2013 ended with the lowest rainfall amounts on record. Recent Sierra Nevada snowpack surveys indicate that 2014 is shaping up to be a challenging water supply year. While there is still the potential for seasonal rains to avoid drought conditions--the Sierras typically get most of their snowpack in January and February--each dry day reminds us even more of the importance to use water wisely.

We will update this website regularly
with Palo Alto's current water supply status, but meanwhile, now is a good time to take actions to make your home and garden as water wise as possible. Luckily, there are many ways to do that while still maintaining a comfortable lifestyle and beautiful landscape.

Your water makes an amazing journey. See how we can enjoy it from source to end use in this short video that reminds us to protect and use it wisely.
Palo Alto water - enjoy it, protect it and use it wisely.

Participation may pre-qualify you for other water conservation rebates. See how easily you can save water and money with free water-wise devices.

Landscape Rebate Program

Water-wise landscapes save water, time and money. Watch our short video. Apply for rebates when you convert lawn to a low-water use landscape design. Converted landscape areas must be covered by at least 50% with approved plants. Irrigation systems, if used within the converted area, must be low-volume drip, micro spray or bubbler.

Local Water Supply

Palo Alto’s water comes from the San Francisco Public Utilities Commission (SFPUC). This high quality water supply consists almost entirely of snowmelt from the Sierra Nevada mountains.
