Water Supply 

California's Water Supply Outlook is Serious Business

Over the years, it has become increasingly evident that water use efficiency is absolutely essential for sustaining adequate and reliable water supplies for southern California. With the Colorado River recovering from a decade-long drought, the uncertainty of a long-term fix for the Sacramento-San Joaquin Bay Delta, and increased population growth, California is faced with long-term water supply reliability challenges.

In addition, the increasing costs of conveying and treating water supplies and replacing aging infrastructure are requiring water purveyors across the state to implement viable and cost-effective solutions to these issues. For a highly urbanized area such as Anaheim, water use efficiency continues to be the most cost-effective approach to ensuring reliable water supplies for its customers.

On April 7, 2017, Governor Jerry Brown issued a declaration which lifted the emergency drought regulations prompted by the historic California drought of 2012-2016. Given the periodic and unpredictable nature of drought events, a long-term framework aimed at ensuring the resilience of our water supplies has been implemented- “Making Water Conservation a California Way of Life.” Prepared by the California Department of Water Resources, in conjunction with the State Water Resources Control Board, California Public Utilities Commission, California Department of Food and Agriculture, and California Energy Commission, this water conservation framework establishes the foundation for our conservation and efficiency goals.

Recent weather events have delivered much needed rain and snow to our watersheds. Groundwater supplies, which represent approximately three quarters of Orange County’s water supply, remain significantly depleted in many areas. While surface water reservoirs can fill very quickly, even in a single season, groundwater basins can take years to fill.  The Orange County Groundwater Basin is still less than half full. Efficient water use, and elimination of wasteful practices, continues to be the most effective approach toward preserving our water resources and supplementing groundwater supplies.

The State Water Resources Control Board has imposed permanent prohibitions for practices that waste potable water, such as:

  • Hosing off sidewalks, driveways and other hardscapes
  • Washing automobiles with hoses not equipped with a shut-off nozzle
  • Using non-recirculated water in a fountain or other decorative water feature
  • Watering lawns in a manner that causes runoff, or within 48 hours after measureable precipitation
  • Irrigating ornamental turf on public street medians
Making water conservation a California way of life ensures that our water demands are met in the future- regardless of the conditions of any one year. Let’s do our part to protect our vital water resources.
