Do Your Part to Stay WaterSmart

October 19, 2021

The 2021 water year was the driest in California in more than a century, but San Diego County continues to have reliable water supplies due to long-term investments in water sources and infrastructure, coupled with extensive water conservation efforts. Per capita potable water use in the San Diego region has decreased by nearly 50 percent since 1990 as residents and businesses continue to adopt WaterSmart practices. The Water Authority’s strategic approach of conservation coupled with investments has been chronicled widely and serves as a model for dealing with the impacts of climate change.

Locally Controlled Supplies

Coordinating with 24 member agencies to develop local water resources is a key component of the Water Authority’s mission to provide a safe and reliable water supply. In fact, a growing number of local water sources across the San Diego region are managed by member agencies — and they are critical to ensuring long-term water supply reliability. Local projects reduce demand and reliance on imported supplies and provide local agencies with more control over costs.

Water Storage

Across the San Diego region, two dozen surface water reservoirs serve a variety of purposes, including storing imported water and capturing runoff from local rainfall. On average, the semi-arid San Diego area receives just over 10-inches of rain annually as measured at the Lindbergh Field weather station situated on the coast – while inland mountain areas can receive more than three times this amount of rainfall.

Water-Use Efficiency

Using water efficiently is a way of life and an important responsibility that comes along with the benefits of living in a beautiful Mediterranean climate like San Diegans enjoy. Over the past decade, residents and businesses across the county have adopted “WaterSmart” plants, irrigation technologies and habits that not only save money, but also create vibrant yards, reduce energy use, protect natural resources and reduce landscape maintenance.

Local Water Use Restrictions

Contact your local water agency for information about water restrictions, conservation programs and incentives, to establish water service, or pay a bill.

Residential Rebates

Residents can take advantage of savings on a variety of water-saving technologies such as high-efficiency clothes washers and toilets, rain barrels and irrigation nozzles. Residents can schedule free WaterSmart Checkups to make their properties more water-efficient.

Commercial Rebates

From free on-farm irrigation assessments of irrigation water to incentives for converting industrial water systems to recycled water service, there are numerous opportunities to improve water efficiency at commercial properties.

WaterSmart Checkup

A WaterSmart Checkup is your free opportunity to receive site-specific water-saving recommendations. You’ll benefit from the perspective of our certified irrigation professionals. And you decide if and when to implement the suggestions.

WaterSmart Makeover Landscape Classes

Using water efficiently is a responsibility but it doesn’t prevent you from having a beautiful landscape. As residents, we can improve how we make the most our water supplies with a fresh approach to low-water landscaping.

WaterSmart Resources

Saving water is easier than you might think. A few simple changes can make a big difference – especially outdoors. More than half of residential water use is for landscape irrigation.
