Of that amount, 29% is used towards agricultural irrigation, 18% towards landscape irrigation, 5% towards groundwater recharge, and less than 1 percent for indirect potable reuse.
Because the number of agencies who initially responded to the survey was limited, water and wastewater agencies are encouraged to update the survey by providing changes or adding new information.
The development of water recycling projects in Los Angeles has provided a way to partially offset the loss of Mono Basin water, and to allow the restoration of Mono Lake to move ahead. Recycled water has been used for a number of years to irrigate vineyards at California wineries, and this use is growing.
Recently, Gallo Wineries and the City of Santa Rosa completed facilities for the irrigation of 350 acres of vineyards with recycled water from the Santa Rosa Subregional Water Reclamation System.
For example, when an industrial facility recycles water used for cooling processes.
A common type of recycled water is water that has been reclaimed from municipal wastewater, or sewage. We educate our communities on pollution prevention and turn wastewater into clean water, returning 67% of what we use back to its source. Through our efforts, water use has dropped 10 percent despite a one million population increase. Access to clean water is important for our safety and vitality.Gray water is reused onsite, typically for landscape irrigation.Use of non toxic and low-sodium (no added sodium or substances that are naturally high in sodium) soap and personal care products is required to protect vegetation when reusing gray water for irrigation.For new buildings over seven stories, the additional cost of providing a dual system added only 9% to the cost of plumbing.For over 35 years, in the Montebello Forebay Ground Water Recharge Project, recycled water has been applied to the Rio Hondo spreading grounds to recharge a potable ground water aquifer in south-central Los Angeles County.National Science Foundation (NSF) International has established a wastewater treatment task group on onsite residential and commercial gray water treatment systems. This standard encompasses residential wastewater treatment systems (similar to the scope of VSF/ANSI Standards 40 and 245) along with systems that treat only the gray water portion. EPA and CDC brought together agency and academic experts to explore the science available for addressing high-priority regional needs in the areas of: For more information visit EPA's Regional Science Workshop website.Through the natural water cycle, the earth has recycled and reused water for millions of years.Learn more Our Technical Assistance Program provides resources for technical and implementation assistance to our member jurisdictions and water providers.This page provides guidelines, tool kits, and model ordinances for various action items in the plan.
