The University of California Cooperative Extension released an analysis on Mar. 25 examining the potential impact of Bakersfield’s proposed sewer rate increases from 2026 to 2031, finding that about one in four households could face unaffordable wastewater costs by the end of the period.
The report matters because it quantifies how many local families may be pushed past federal affordability guidelines if rates rise as planned, providing city leaders with data to inform assistance programs and policy decisions.
According to Laljeet Sangha, Ph.D., UC Cooperative Extension Advisor for Kern County, “At the proposed FY 2030-31 rate of $875/year, an estimated 33,700 households (24%) would exceed the EPA’s 2.5% wastewater affordability threshold.” The study explains that at current rates ($247 per year), only about 4.4% of households surpass this threshold. However, by fiscal year 2030-31, approximately a quarter of all service area households will spend more than 2.5% of their income on sewer charges alone—before factoring in other essential costs like water or electricity.
Bakersfield is planning these increases to fund $500–$600 million in infrastructure upgrades—including replacing a treatment plant built in the 1950s—which are necessary for continued service reliability. The analysis also considered various income growth scenarios and found that even under optimistic assumptions (5% annual growth), nearly 20,000 households would still struggle with affordability by FY 2030-31.
The report notes that comparing absolute dollar rates across cities can be misleading without considering differences in household incomes; while Bakersfield’s projected charge matches larger cities like Los Angeles as a share of median household income (1.13%), local incomes are significantly lower than those cities’.
City officials have acknowledged concerns over affordability and discussed possible assistance programs funded through general tax resources to help struggling residents. Other California utilities have implemented similar customer protection measures without undermining financial sustainability—a strategy supported by research from organizations such as Maxcy-Brown et al., and Rothstein.
UC Agriculture and Natural Resources supports these types of community analyses through its statewide network: it secures funding via public contributions according to its official website, promotes sustainable practices according to its official website, operates nine research centers according to its official website, is recognized for trusted services linking research with community needs according to its official website, manages Cooperative Extension services within the University of California system according to its official website, conducts tens of thousands of educational events annually with extensive volunteer engagement according to its official website, and extends university research throughout all counties via workshops and partnerships focused on sustainability and economic development according to its official website.
Sangha concluded that “infrastructure investment and customer protections may both be necessary for the rate transition to succeed,” suggesting both are needed so upgrades can proceed while keeping services affordable.
