Cal Water: Utility water conservation programs save water and lower customer bills

  • Cal Water: Utility water conservation programs save water and lower customer bills

About the entity

California Water Service Group
California Water Service Group (NYSE:CWT) is the third-largest publicly traded water utility in the United States, providing high-quality water and wastewater services to about two million people in more than 100 communities through four subsidiaries

Cal Water, the largest water utility regulated by the California Public Utilities Commission, released a new study demonstrating that its water conservation efforts from 2008 to 2019 significantly lowered water use, which decreased operating costs and in turn reduced customer bills by as much as 20 percent from what they would have been without the conservation efforts.

Water conservation has been shown time and again to be the lowest-cost source of supply, because when less water is used, costly investments required to produce additional water supplies can be deferred and potentially avoided.  This study, “The Economic Value of Water Efficiency,” is yet another proof point showing that water conservation promotes affordability.

Because of its commitment to both water conservation and affordability for customers, Cal Water supports SB 1469 (Sens. Bradford/Becker, Asm. Rivas), a bill that allows water utilities to implement decoupling. Decoupling is a tool that ensures that water utilities do not benefit when they sell more water.

Cal Water substantially increased its water conservation efforts beginning in 2008, when the California Public Utilities Commission (CPUC) allowed the company to establish a pilot program that implemented decoupling. An August 2020 decision by the CPUC ordered that decoupling would end beginning in 2023. Passage of SB 1469 would allow this valuable mechanism to continue and enable utilities to continue to promote conservation, which is especially critical in California given the drought environment.

“The Economic Value of Water Efficiency,” is yet another proof point showing that water conservation promotes affordability.

“As California learns to adapt to more frequent and severe droughts and aims to make conservation a way of life, it is critical we better understand and leverage policies and conservation practices that result in the most bang for the buck,” said Martin A. Kropelnicki, President and CEO. “Our study shows that conservation practices work to not only save water, but also save customers money. Passage of SB 1469 will ensure we are able to keep our focus on water conservation efforts that will be critical to adapting to climate change and, at the same time, improve water affordability.”

“SB 1469 is common-sense policy. We know decoupling will help lower water use, we know customers will pay less when they use less water, and we know conservation is the most cost-effective way to increase water supplies,” said Senator Steven Bradford, D-Gardena. “This is a classic win-win-win bill.”

“California needs to take strong action to address ongoing drought and climate change,” said Senator Josh Becker, D-Peninsula. “Decoupling has a proven track record of decreasing water use and lowering water bills.”

The water conservation initiatives supported by SB 1469 not only help water suppliers adapt to climate change but are also an important tool to reduce greenhouse gas emissions. California’s Department of Water Resources estimates that about 12 percent of California’s total energy use is related to water, including pumping, treatment, and distribution. Reducing the amount of water used creates a corresponding reduction in energy use.

“This study demonstrates that Cal Water’s investments in water efficiency not only saved water but also saved customers money on their water bills, and the results align with similar analyses the Alliance for Water Efficiency has conducted for Los Angeles; Tucson, Ariz.; and other communities,” said Ron Burke, President and CEO of the Alliance for Water Efficiency. “Passage of SB 1469 is needed to ensure water agencies aren’t penalized for water efficiency programs that address California’s water crisis and lower water bills.”

There is empirical proof that utilities with decoupling mechanisms are better able to promote and achieve significant levels of water conservation than those without. A peer-reviewed study of California’s last drought found that CPUC-regulated water suppliers that were able to implement decoupling “adopted more aggressive conservation measures, were more likely to meet state conservation standards, and conserved more water.”[1]

“Conservation is the most cost-effective means of ensuring there are sufficient water supplies for both people and our environment,” concluded Kropelnicki. “SB 1469 will encourage conservation and benefit customers, the environment, and fulfill Cal Water’s commitment to enhancing the quality of life in the communities it serves.”
