Why did the water bill on my El Segundo or Hawthorne building go up in 2026?

Published July 25, 2026

The CPUC approved Golden State Water's 2026 step increase, effective January 1, lifting adopted revenue about 32 million dollars over 2025 across a Southwest system that includes parts of El Segundo and Hawthorne.

If the water bill on your El Segundo or Hawthorne building jumped this January, the meter did not break. On January 1, 2026, Golden State Water Company put a new rate step into effect after the California Public Utilities Commission approved its 2026 increase. The company reported the change lifting adopted water revenue, less water supply cost, about 32 million dollars over 2025 levels systemwide. Both cities sit inside the affected Southwest service area.

What actually got approved

Golden State Water operates on a three year rate cycle covering 2025 through 2027. Rather than one big jump, the CPUC approved a rate case that steps up in stages, and the company has to pass an earnings test in each of its ratemaking areas before it can turn on the second and third year increases. It cleared that test for 2026, so the step took effect on January 1.

The company's own statement puts the 2026 change at roughly 32 million dollars in higher adopted water revenue, less water supply cost, compared to what regulators adopted for 2025. When the rate case was first filed, the water revenue increase sought for 2026 was reported at about 4.42 percent. I want to be honest about that number. It is a systemwide, application stage figure, not a promise that your specific meter went up exactly 4.42 percent. Water rates are set per ratemaking area and vary by meter size and usage tier, so the real change on your bill depends on your service area, your meter, and how much water the building actually ran.

The practical takeaway is simpler than the regulatory language. Regulated water is not a market you shop. When the CPUC signs off, the new rate is the new rate, and it shows up on the next cycle whether you budgeted for it or not.

Are El Segundo and Hawthorne even in this service area?

This is the part worth checking, because neither city is served entirely by Golden State Water. According to Golden State Water's own description of its Southwest system, that system covers more than 54,000 connections across Southwest Los Angeles County. It includes all of Gardena and Lawndale, and portions of Carson, Compton, El Segundo, Hawthorne, Inglewood, Redondo Beach, and several unincorporated pockets like Del Aire, Lennox, and El Camino Village.

Notice the word portions. Parts of El Segundo and Hawthorne are on Golden State Water. Other parts of those same cities are served by a different provider entirely, so the address on the deed decides whether this increase touches your building at all. Before you assume anything, look at an actual recent bill for the property and confirm the provider name at the top. If it says Golden State Water and the service address falls in the Southwest system, this increase is yours to plan around.

What this means for your building

Water is one of the quiet line items that erodes an owner's margin without ever announcing itself. It is not glamorous, it does not show up in the listing photos, and it is almost never the reason a building underperforms on its own. But it compounds. A regulated increase like this one does not reverse next quarter, so the smart move is to fold it into the operating budget now rather than discover it at tax time.

Who eats the increase depends on how the building is set up. In much of the South Bay, water on a single family rental or a small two to four unit building is owner paid, bundled into operating expenses and quietly lowering net operating income. On larger or newer buildings, some owners bill water back to residents through a ratio utility billing system, often called RUBS, which allocates the master meter cost across units by a formula. If your building is on RUBS, a rate increase partly passes through to residents. If it is not, the full increase lands on you.

A few grounded moves worth making this year. First, pull the last twelve months of water bills for the property and look at the trend, not just the January figure, so you can see the real annualized cost rather than one spike. Second, if the building is owner paid and the water cost has been creeping, this is the year to check the plumbing basics that actually move a water bill, running toilets, a dripping irrigation valve, an unlogged leak on a shared line. A single silent leak can dwarf a 4 percent rate step. Third, if you have been curious about RUBS and the building qualifies, understand that California regulates how utility billing is disclosed and administered in a lease, so that is a conversation to have with a professional before you change anything, not a switch you flip mid tenancy.

None of this is a reason to panic about an El Segundo or Hawthorne building. These are strong, tightly held rental markets, and a regulated water step is a normal cost of operating in a well run water district. The goal is simply to see it, name it, and budget it, so it never surprises you.

Common questions

Does this increase mean my rent can go up to cover it?

Rising operating costs and what you can legally charge in rent are two separate questions. In California, most residential rent increases are governed by state and local caps, and a jump in your water bill does not by itself unlock a larger increase. If the building is on RUBS, a portion of the water cost may already flow to residents through the utility allocation rather than through base rent. Before you adjust anything, confirm the rules that apply to your specific property with a licensed professional.

How do I know if my building is actually on Golden State Water?

Look at a recent water bill for the property and read the provider name at the top. Because only portions of El Segundo and Hawthorne sit in the Southwest system, two buildings a few blocks apart can have different water providers. If the bill says Golden State Water and the service address is in the Southwest area, this 2026 increase applies to you.

Will there be another increase after this one?

The current rate cycle runs 2025 through 2027, and the structure allows for step increases in the second and third years, each gated by an earnings test the company must pass first. In plain terms, another step in 2027 is possible but not automatic. Budgeting for a modest annual water cost increase through the end of the cycle is the conservative planning assumption.

Last verified: July 25, 2026. Rate figures and service area boundaries come from Golden State Water Company and CPUC statements and can change with future filings. This is general information for property owners, not legal advice. Confirm how any rate change, rent adjustment, or utility billing arrangement applies to your specific building with a licensed professional.
