Who to call first about the water service line

BelowGrid has no first-call guidance on file from Golden State Water Company, Artesia System about the water service line.

The documents this answer is built on

Who is responsible for which part

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, Artesia System's own statement.

Golden State Water Company, Artesia System
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. Check the name on your water bill first. The State's register puts Golden State Water's Artesia system across about 99% of Hawaiian Gardens and no other system over 1% of it. The company's own Central Basin East page says it serves customers "including portions of Artesia, Cerritos, Downey, Hawaiian Gardens, La Mirada, Lakewood, Long Beach, Los Alamitos, Norwalk, Santa Fe Springs, Whittier and adjacent county territory", so not every address is necessarily its customer; if another utility bills you, its own rules apply, not these.

What Golden State Water Company, Artesia System reported to the State about service-line materials

Federal rules required every community water system to inventory its service lines and publish the result. These are the figures this one filed.

The inventory records what each line is made of: lead, galvanized requiring replacement, non-lead, or lead status unknown. “Still unclassified” counts the lines whose material has not been identified. It does not mean they are lead.

Golden State Water Company, Artesia System has classified more of its service lines than most of California: 0.00% of its lines are unclassified, against 9.2% statewide.

What this page cannot 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 99% of Hawaiian Gardens' land inside the boundary it maps for Golden State Water Company, Artesia System. Measured 26 Sep 2026.
  • 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 4 Sep 2026. They may not reflect its current inventory - ask the water system to confirm anything about a specific address.

Your other pipe: the sewer lateral

For the sewer lateral, Hawaiian Gardens gives the opposite answer to the one above:

Hawaiian Gardens writes no sewer ownership rule of its own and borrows the County's. Section 13.08.010 of its municipal code adopts Title 20, Utilities, Division 2 of the Los Angeles County Code as the City's sanitary sewer ordinance - the division "which may be amended from time to time by the County of Los Angeles to comply with new State permits", and which regulates "the use, operation, maintenance, and repair of the City sanitary sewer system". Inside that adopted division, section 20.24.080 provides that all house laterals "shall be maintained by the owner of the property served in a safe and sanitary condition", and section 20.20.130 defines a "house lateral" as "that part of the sewer piping within the street or right-of-way which extends from the property or sewer right-of-way line to a construction with the main-line sewer". The length the City's ordinance puts on the owner is the length under the road.

Your sewer lateral is yours to the main; your water line stops being yours at the meter.

Same trench, separate authorities, decided separately.
