San Diego's Water Supply

There is not a moment to waste! We're in a water crisis.san diego drinking water

San Diego County does not have enough local water supply to meet our demands. Our county draws 80 percent of our drinkable water from outside the area. In the City of San Diego, that number soars to 90 percent. Rather than solving our own problems, we suck almost half of what we use from the Colorado River (named the Most Endangered River in America in 2013) and another half from the San Joaquin River Delta in Northern California.

Importing water to San Diego means using energy, a lot of it. According to the California Energy Commission, transporting water throughout the state requires 19 percent of California's electricity, consumes 32 percent of the state's natural gas supplies and uses 88 million gallons of diesel, exacerbating climate change concerns.

San Diego Coastkeeper partners with a variety of organizations to research and advocate for solutions. The Equinox Center published a report in 2010 that provides a non-partisan, independent analysis of water supply alternatives. Read the summary or full report.

Turning on a tap in San Diego County is expensive and unsustainable. So we have to make important decisions now to reduce our water demand and boost our supply.

A new vision for water management

wastewater recylingWe must change the way we discuss water. Stormwater, wastewater and drinking water options are a comprehensive water quality and water supply system, not isolated issues.

San Diego Coastkeeper helps in developing an integrated regional water plan that addresses San Diego County's water supply issues by prioritizing conservation and water reuse and recycling before options like water imports and desalination.

Following nearly two decades of advocacy by San Diego Coastkeeper and our partners, in 2013, the City of San Diego councilmembers unanimously supported a plan to transform the city's wastewater management system into a source of 80 million to 100 million gallons per day of clean, pure drinking water. This strategy, which works in Orange County, will replace approximately 50 percent of the imports used in the City of San Diego. We will see this plan come to fruition in a visionary, responsible manner by working with city, regional and state decision-makers. Sign up for a tour of the demonstration project to learn more. Or read the 2005 Water Reuse Study that put the plan in motion.

Coastkeeper represents this thinking at the state level as a stakeholder on the planning group for the Integrated Regional Water Management program, a local water resources management approach preferred by the governor, California Department of Water Resources and State Water Resources Control Board. It aims to secure long-term water supply reliability within California by connecting water supply and the environment and pursuing projects that benefit water supplies, water quality and our community.

Drinkable Facts

  • Recent research estimated that gastrointestinal illnesses caused by contaminated coastal waters translated into an annual economic loss of $21 or $51 million.
  • Recent research estimated that contaminated coastal waters at beaches in Los Angeles and Orange County caused between 627,800 and 1,479,200 cases of gastrointestinal illnesses.
  • The Potable Water Reuse facility could reduce the cost to upgrade the Point Loma sewage treatment facility by almost 50%.
  • The State Water Project, which brings water from Northern California down to Southern California, uses an average 5 billion kWh/yr of electricity - making it the largest single energy user in the state.
