Golden State Water Company wants to raise water bills by roughly 30% for customers across Los Angeles and Orange counties by 2030, and the average residential customer would end up paying about $25 more per month if regulators sign off. The utility filed its request with the California Public Utilities Commission in July 2026, kicking off a review process that will stretch over the next year and touch tens of thousands of households in the San Gabriel Valley, South Los Angeles County and North Orange County.
The formal filing, Application 26-07-001, asks for a $95.18 million increase for 2028 alone, a 19.40% jump, followed by smaller step increases of 6.88% in 2029 and 6.57% in 2030, according to CPUC Online Documents. The California Public Advocates Office filed a formal protest against the proposal, calling Golden State’s proposed spending excessive, and the commission is expected to issue a decision by November 2027. As the Long Beach Press-Telegram reports, the utility serves customers in Monrovia, El Monte, Pomona, Anaheim, Inglewood, Long Beach and Los Alamitos, among other communities.
Infrastructure Spending Behind the Ask
Golden State Water says the increase would fund more than $180 million in additional infrastructure spending, including $21 million in San Gabriel Valley upgrades for water treatment, water quality and system reliability, per the Press-Telegram’s reporting. The Placentia and Los Alamitos service areas are each slated to receive more than $34 million in investments. In Los Angeles, the company also plans to replace two 1.5-million-gallon reservoirs at the Florista plant.
Some of that spending traces back to federal mandates rather than local choice. The U.S. Environmental Protection Agency finalized nationwide drinking water rules in April 2024, setting enforceable limits of 4.0 parts per trillion for PFOA and PFOS, giving utilities until 2029 to build the treatment infrastructure needed to comply, according to the U.S. Environmental Protection Agency. The Press-Telegram notes the new PFAS regulations may increase utility costs across the board, and Golden State is also folding in the Artesia Service Area, which it agreed to acquire for $5.25 million under a settlement filed with Cal Advocates in July 2026, with rates fully consolidated in the 2028 case.
A Familiar Pattern for Southern California Water Bills
This isn’t Golden State’s first big ask. The utility proposed a 22.95% increase in its previous three-year rate cycle, but that request was ultimately reduced by more than half before the CPUC approved final increases of 10.52% in 2025, 4.26% in 2026 and 4.07% in 2027. Gregory Pierce told the Press-Telegram that Public Advocates’ protests against water rate increases are very typical, a pattern that tends to blunt utilities’ initial asks without eliminating them…
