Local rep pushing bill to boost use of recycled water
Feb. 13—Sen. Jerry McNerney, D-Pleasanton, on Tuesday introduced new legislation on Tuesday that would boost the use of recycled water in California.
Senate Bill 31 would also enhance the state's fresh water supply by allowing businesses, homes, and agencies to expand their use of recycled water for irrigation and other uses, rather than relying on drinking water.
"Instead of water wars pitting one region of the state against the other — North versus South — California must develop commonsense solutions that enable us to use the water we have more efficiently," McNerney said. "SB 31 is a pragmatic approach that will enhance our supplies of fresh water by expanding the use of recycled water for irrigation and commercial uses. It will also help protect the state during devastating droughts caused by climate change."
Recycled water is wastewater that has been treated to make it safe for instances in which using drinking water is unnecessary. It is commonly used in irrigation and groundwater recharge, among other uses.
California law requires state and local agencies to use recycled water for irrigating parks, golf courses, cemeteries, landscaping along highways, and other uses when possible. In addition, state law allows agencies to require the use of recycled water for toilet and urinal flushing in public buildings.
Lodi Public Works Director Charles Swimley said the city currently uses very little recycled water, but it will be exploring opportunities associated with the bill for expanding its recycled water infrastructure.
"While we have existing recycled water infrastructure in some of our subdivisions, we don't serve recycled water in the city proper," he said. "We do however utilize approximately 2,700 acre-feet of recycled wastewater annually to irrigate the land application areas that are located at the White Slough Water Pollution Control Facility."
Governor Gavin Newsom's Water Supply Strategy aims to meet a goal of recycling 1.8 million acre-feet per year by 2040.
California currently uses more than 700,000 acre feet of recycled water a year, saving the state roughly the equivalent of enough drinking water for 1.4 million households.
SB 31 would enable parks to expand the use of recycled water and ensure that using recycled water in lakes and golf courses, among other "decorative" areas, isn't deterred by overly burdensome regulations.
It also requires homeowners' associations to use recycled water, where available, to irrigate outdoor common areas, and makes sure that homeowners' associations won't have to install new plumbing systems to use recycled water.
In addition, the bill allows food handling and processing facilities to use recycled water for toilet or urinal flushing or outdoor irrigation as long as the recycled water doesn't enter a room where food handling or processing occurs.
"Increased use of recycled water is imperative to ensuring local communities have access to safe and reliable drinking water," WateReuse California managing director Brenley McKenna said. "WateReuse California thanks Senator McNerney for introducing SB 31, which will update the Code of Regulations and expand the allowable uses of recycled water throughout the state. Aligning regulations with advancements in technology and increased investment in recycled water are critical to implementing the Governor's Water Supply Strategy."
