Water Conservation Success & Remaining Potential

How do we accelerate progress?

Juliet Christian-Smith

Pacific Institute


California can conserve and has

California Can Conserve, and Has!

  • Urban

    • Since 1980 per capita water use has decreased by up to 33% in some regions

    • Now at 192 gallons per capita per day

  • Agriculture

    • Has invested approximately $1.5 billion of in water conservation and efficiency upgrades (AWMC 2009)

    • 60% of irrigated acreage is gravity-fed (2001)

      How do we accelerate progress?

Waste Not, Want Not: Urban Water Conservation Potential

Potential Water Savings

Averages 33%


Sustaining california agriculture agricultural water conservation potential

Sustaining California Agriculture:Agricultural Water Conservation Potential

  • Efficient Irrigation Technology – shifting from flood irrigation to sprinkler and drip systems;

  • Improved Irrigation Scheduling – using local climate and soil information to schedule irrigation; and

  • Regulated Deficit Irrigation – applying RDI to almonds, pistachios, wine grapes, raisins.

Benefits of reducing applied water

Benefits of Reducing Applied Water

  • Improves water quality

  • Increases the volume and improves timing of instream flows

  • Reduces need for capital-intensive infrastructure

  • Reduces vulnerability to water-supply constraints


2 recognize and analyze successes

2) Recognize and Analyze Successes


3 make policy relevant recommendations

3) Make Policy-Relevant Recommendations

  • Update water efficiency standards.

  • Provide financial incentives to facilitate the adoption of water conservation and efficiency improvements, target areas with most potential.

  • Improve water use monitoring, particularly for outdoor water consumption.

  • Eliminate pricing policies that subsidize the inefficient use of water.
