Recycled water is treated wastewater that has undergone additional filtration and disinfection processes to make the water safe for non-potable (non-drinking) uses. Since April 2003, Regional San’s cutting-edge Water Recycling Program (WRP) has provided an environmentally responsible and safe water supply for non-potable purposes, such as landscape irrigation, industrial uses, and environmental restoration.

A Successful Partnership

The WRP is a partnership between Regional San and the Sacramento County Water Agency (SCWA). Regional San provides recycled water treatment and monitors recycled water quality, while SCWA distributes recycled water to customers and monitors recycled water use.

Regional San’s water recycling facility is located on the property of the Sacramento Regional Wastewater Treatment Plant (SRWTP) near Elk Grove. Currently, the WRP provides up to 3.5 million gallons per day of recycled water to neighboring parks, landscaped street medians and commercial and school sites in the Laguna West, Lakeside and Stone Lakes developments.

Benefits of Recycled Water

Increased use of recycled water can reduce the region’s dependence on precious groundwater and surface water supplies, especially during drought periods and times of high potable water demand and low supply. Given these important benefits of water recycling, it’s easy to see why Regional San is committed to water recycling. Moreover, once major treatment plant upgrades are completed, all of Regional San’s treated effluent (about 130 million gallons per day) will meet the standards for recycled water, thereby significantly expanding its potential use. (Visit EchoWater Project for more information on the plant upgrades.)

Smart and Safe

Recycled water treated at Regional San’s water recycling facility meets and exceeds the California Department of Health Services’ most stringent irrigation requirements for recycled water. There has never been a documented health-related problem traced back to recycled water when used in accordance with state guidelines.

• California’s recycled water standards are among the most stringent in the world.
• Tertiary treated recycled water is virtually pathogen-free.
• Recycled water is treated to a level very close to drinking water quality.

Program Goals

In January 2004, Regional San’s Board of Directors approved the concept for a large-scale WRP, which includes the following goals:

• Increase water recycling throughout the Sacramento region on the scale of 30 to 40 million gallons per day over the next 20 years.
• Increase utilization of recycled water to expand Regional San’s effluent management options beyond continued discharge to the Sacramento River.
• Increase utilization of recycled water to meet growing non-potable demands, allowing Sacramento area water purveyors to reduce demands on their existing potable water supplies and reduce the need for additional water supplies in the future.
