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
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
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.
Regional San’s10-Year Update Report details the progress the District has made between 2004 and 2014 in efforts to advance its various water recycling programs and projects.
The report fulfills a number of objectives. First, it updates and summarizes our activities related to the water recycling program over the last 10 years. It confirms Regional San’s commitment to water recycling in the Sacramento region and provides additional awareness, education and acceptance of the program to stakeholders and ratepayers. It also provides information for stakeholders who are potentially interested in participating in the expansion of the Water Recycling Program. And finally, the report strives to build consensus and understanding for the need to increase production of water recycling in the region.
