Who owns the water service line in Gardena, CA
Golden State Water owns the service pipe, the curb stop, the meter and the meter box, and says plainly that it maintains them: "We maintain the pipes up to the water meter, but any leaks or issues beyond the meter are the responsibility of the property owner." The curb stop, which folklore treats as the boundary, is expressly the company's. This is Golden State Water Company, Southwest District's own statement.

Why, and what to do
Where the responsibility divides
- Golden State Water Company, Southwest District
- The run from the main to the meter, by title and by the company's own undertaking. Its CPUC tariff states that "the service pipe, curb stop, meter, and meter box furnished by or on behalf of the utility and located wholly or partially upon a customer's premise are the property of the utility". The tariff stops at title, but the company answers the repair question itself, on its customer pages: "Golden State Water is responsible for the underground service line that connects their property to the water main", and, on a high bill, that investigating past the meter is the customer's job "since Golden State Water is only required to maintain the water lines up to the meter".
- The property owner
- The piping from the meter to the building, on the company's own division: "any leaks or issues beyond the meter are the responsibility of the property owner". Golden State puts the same split in its service-material inventory, where it says the property owner owns the service line from the meter box to the home or building foundation.
- What else is worth knowing
- Where the promise lives is worth knowing if you ever have to hold the company to it. The filed tariff - the document the Public Utilities Commission approves - gives ownership and stops there; the undertaking to maintain is on Golden State's own customer pages instead. Those pages are the company speaking about its own obligations and are the best answer it publishes, but they are not a tariff and can be reworded without a filing. Two things follow. If the leak is on the street side of your meter, start from the company's own sentence that it maintains the pipes up to the meter. And do not read the tariff's access clause as a repair duty: it lets the company reach its equipment on your land, which is not the same as promising to fix it - the promise is the sentence on the customer page, not that one.
What Golden State Water Company, Southwest District has told the State
Federal rules required every community water system to inventory its service lines and publish the result. These are the figures this one filed.

Where else this answer applies
Golden State Water Company, Southwest District also supplies one other place with a page here, and the statement above is the same one that governs it: Lawndale. Each of them settles the sewer lateral separately, often under a different authority from this one.
What this does not tell you
- This describes who is responsible for which part of the pipe. It is not a record of what your own service line is made of.
- The State's service area map puts effectively all of Gardena's land inside the boundary it maps for Golden State Water Company, Southwest District. Measured 2026-09-11.
- 53,883 is the whole of Golden State Water Company, Southwest District's reported inventory, not this city alone. The State's file records no city for these lines, so they cannot be counted per city.
- Classified does not mean inspected. Across California only 22% of service lines were established by field inspection; most of the rest come from records, the year of construction, or a predictive model.
- These figures were submitted to the State by the water system itself and were read on 2026-09-04. They may not reflect its current inventory - the system's own page is the place to confirm anything about a specific address.
Your other pipe has a different answer
For the sewer lateral, Gardena gives the opposite answer to the one above:
The property owner maintains the sewer lateral, and in Gardena the code's own definition puts the run under the road on them explicitly: a "house lateral" here means the pipe from the property line to its connection with the main sewer. The City maintains the main and claims no part of the lateral.
Your sewer lateral is yours to the main; your water line stops being yours at the meter.
