Delta Diablo Residential Recycled Water Fill Station

UPDATE

Recycled Water Residential Fill Station is Closed

We would like to thank all customers in our service area who have contributed to potable (drinking) water conservation efforts and looked to sources, such as recycled water, to meet their irrigation demands throughout the 2015-16 drought.  Due to the lack of participation, cost to maintain and operate the Recycled Water Residential Fill Station (RWRFS), and lift in mandated conservation efforts imposed by water purveyors (based on the Governor's drought restriction executive order), the RWRFS is now closed.

Recycled Water Residential Fill Station:

Between 2011 and 2014 California experienced the driest years since historical record-keeping began back in 1898.  This, combined with the lack of precipitation from 2015’s El Niño year, led Governor Jerry Brown to institute a mandatory 25% reduction in water usage beginning June of 2015.  In July, Delta Diablo opened a pilot Recycled Water Residential Fill Station (RWRFS) to aid with California’s state-wide drought.  With the drought emergency declaration, several water purveyors were required to make drastic reductions in water usage to meet the 25% curtailment.  Reduction efforts were quickly passed on to the public with the implementation of water use restrictions and fines.  Most cities limited overall water usage, irrigation days, and imposed fines for excessive water usage.  This gave Delta Diablo the opportunity to provide the public with an environmentally defensible option to maintain their lawns, gardens, and landscaping through the drought, while helping to conserve drinking water supplies.

The RWRFS originally opened in July 2015 through December, registering 480 residents and giving away over 2 million gallons.  Northern California experienced normal rainfall in 2015-16, however, Southern California had below-average precipitation, resulting in the continuation of the drought declaration.  The RWRFS reopened in May 2016, remaining open until October while distributing an additional 2 million gallons and registering another 120 residents.  The 2016-17 winter was the wettest on record for Northern California, surpassing the last record set in 1982-83.  In February, Shasta, Oroville, and Folsom Lake began simultaneously dumping water for flood control.  Lake Oroville was required to use their emergency overflow for the first time in 48 years.  In response to the heavy precipitation Governor Brown lifted the drought declaration on April 7, 2017.  With the end of the drought, Delta Diablo decided to offer one more year of the RWRFS.  With copious amounts of precipitation, and the rescind of the drought declaration, many residents turned back to potable water to irrigate their lawns and gardens.  The RWRFS opened from July through October 2017; however, participation dwindled to 60 users, and recycled water distribution dropped to half a million gallons for the season.

In total, from July 2015 through October 2017, Delta Diablo registered 600 residents who made over 18 thousand visits and offset domestic (drinking) water usage by claiming over 5 million gallons of recycled water.  While recycled water is a great option to offset domestic water use, driving and hauling of water can become expensive and burdensome.  The gas used to drive to and from the fill station results in a negative impact on our environment, increasing our carbon footprint.  There are currently no plans to reopen the RWRFS, however, evaluation for reopening of the Residential Fill Station in the future will include; drought conditions, potable water supply limitations resulting in a mandatory conservation, and potable water use restrictions that impact residents within the District’s service area.

Recycled Water Containers:

Containers used for recycled water can be reused for potable water storage, however, we would like to remind the public that recycled water has not been treated to drinking water standards and should not be ingested or allowed to run off into storm drains.  Furthermore, any containers used for recycled water must be thoroughly cleaned and disinfected (1 tablespoon of bleach per quart of water) before they can be used for potable (drinking) water.  

Recycled Water:

Delta Diablo is currently partnered with several cities, schools, businesses, and agencies to effectively use Recycled Water to offset potable (drinking) water usage.  For more information about recycled water and what it is used for, click here

Recycled water produced by Delta Diablo meets all regulatory requirements for unrestricted, non-potable uses.  For recycled water quality data, click here

Water Conservation Efforts:

California has experienced several episodes of drought and increasingly drastic fluctuations in weather throughout the century. Drought and weather fluctuations caused by weather conditions, economic and political actions, as well as population growth, and farming.  To provide a sustainable future for generations to come, water conservation must be a way of life.  Delta Diablo encourages people to look at ways to continue to conserve water in the future.  Here are some ways to do your part and help conserve:

  • Irrigate efficiently – Do not over water.  Decrease water usage as the seasons change and temperatures decline.  Water for short periods, allowing the water to be absorbed and not run off into storm drains.  Water in the early morning when it is cooler and there will be less evaporation.
  • Tune-up your irrigation system – Repair any broken sprinkler heads or leaks.  Perform a coverage test after mowing to make sure you don’t get ponding, dry spots, or overwater.
  • Plant drought tolerant gardens – replace plants with ones that need only a small amount of water.  Replace grass with rock or artificial turf.  California currently offers rebates for replacing your turf at www.saveourwaterrebates.com.
  • Replace water fixtures – Replace shower heads, toilets, and faucets with low-flow, low-water usage versions.  Replace dishwashers and other water using appliances with energy efficient, low-flow versions.  Many of these products offer incentive rebates, which can save you money.
