The California State Water Resources Control board has released its third annual Drinking Water Needs Assessment, which describes the overall health of the state’s water systems and domestic wells and helps direct the funding and regulatory work of the Safe and Affordable Funding for Equity and Resilience (SAFER) drinking water program.
The report for the first time examines the causes behind chronically failing water systems and incorporates community-level socioeconomic factors, including customers’ ability to pay, into its analysis of the risks systems face.
The analysis and findings will guide where the State Water Board focuses its technical assistance and how it prioritizes funding in the 2023-2024 Fund Expenditure Plan, due to come before the board this fall. Across all its funding sources, the SAFER program provided more than $758 million in 48 planning and construction projects in 2022, and over $21 million in technical assistance. Thanks to increased infrastructure funding from the state’s General Fund and the federal Bipartisan Infrastructure Law, assistance for drinking water projects increased 150% from 2021.
In 2022, the SAFER program completed 27 water system consolidations, with another 316 currently in the planning or funding stages. Since the SAFER program began in 2019, 94 consolidations have been completed, benefitting 56,000 people, and overall, 185 more water systems are providing safe drinking water, benefitting 1.2 million Californians.
“Our Needs Assessment helps us ground our technical support and funding decisions for drinking water solutions in solid data so we can target assistance to where it can have the most impact,” said Darrin Polhemus, deputy director with the Division of Drinking Water. “Each year, we accumulate more lessons and data that enable us to add depth and sophistication to our SAFER program work. Our regular engagement with the public has been extremely valuable to updating our methodology so that our analysis stays relevant and can be used — and shared — as an effective tool for us to build sustainable solutions collectively.”
Key findings of the 2023 Needs Assessment are:
- Of the 3,053 water systems analyzed on January 1, 2023, 381 systems were listed as failing, meaning they do not meet one or more key Human Right to Water goals for providing safe, accessible or affordable drinking water and/or maintaining a sustainable water system. Collectively these failing systems serve approximately 787,000 people.
- At least half of failing water systems (or 5% of all public drinking water systems statewide) have consistently failed for three or more years. Ninety-seven percent of those have fewer than 3,300 connections, with the majority exceeding safe water quality levels for primary contaminants such as arsenic.
- Forty-two percent of the systems on the failing list are considering consolidation or are in the course of developing a long-term solution with SAFER technical and funding support. Consolidation with larger, high-capacity systems is one sustainable solution to help communities secure long-term access to safe drinking water.
- Of the 2,672 systems not on the failing list, 512 systems are at risk of failing due to water quality or shortage issues, their customers’ inability to pay, or limited technical, managerial or financial capacity. Collectively these at-risk systems serve approximately 1.3 million people.
The report examines the risks that financial limitations of a customer base can pose, leaving some of these water systems unable to collect sufficient revenue to meet long- term operational and maintenance expenses or invest in necessary upgrades. Using an updated methodology that includes poverty and housing costs to assess community- level affordability, the report found that approximately 23% of systems that serve disadvantaged or severely disadvantaged communities face a medium-to-high affordability burden. In contrast, only about 9% of systems that serve non-disadvantaged communities do.
"It's said that you can't manage what you don't measure," said Jennifer Clary, California Director at Clean Water Action. "That was true for a very long time for small California communities. The Drinking Water Needs Assessment provides critical information about who lacks access to safe drinking water and why, as well as who is at risk of losing access in the future. It's an invaluable resource."
