Who owns the water service line in San Jacinto, CA

Eastern Municipal Water District owns the water service connection from its main to and including your meter, and its Administrative Code says "the expense of maintenance, repairs, and renewal of such service connections and meters, due to normal wear and tear, shall be borne by the District". Your side starts at the meter: "water pipes and appurtenances downstream of the meter are the property of the customer who is responsible for water use, operation and maintenance." Note that the same District answers the opposite way for your sewer lateral, which is yours the whole way to the main. This is Eastern Municipal Water District's own statement.

Where the responsibility divides

Eastern Municipal Water District: The service connection and the meter, owned and kept up at the District's own expense. Administrative Code section 5.104(c) provides that "service connections and water meters installed or accepted for use by the District are the property of the District", and that "the expense of maintenance, repairs, and renewal of such service connections and meters, due to normal wear and tear, shall be borne by the District". Section 5.506, "Ownership of Service Connections", repeats both. The Code's definition of a service connection is the piping and appurtenances necessary to "deliver water from the District's water main to a Customer's property, including the meter, meter box, valves, and appurtenant equipment within the meter box".
The property owner: Everything downstream of the meter. Section 5.104(c) states that "water pipes and appurtenances downstream of the meter are the property of the customer who is responsible for water use, operation and maintenance". Under section 5.106(b) the applicant designs the run from the point of connection onwards, service lateral, meter and "all post-meter piping and appurtenances", so that pressure and flow at each floor meet the requirements of whoever issues the building permit. Where District pressure falls below 50 psi or rises above 80 psi, the customer is "responsible for installing devices, inclusive of pressure regulation devices and/or pressure boosting devices, and any other applicable devices, at their cost", and shall "own, operate, maintain, repair" them.
What else is worth knowing: Two things decide what you pay, and one of them is which valve you touch. The District's expense covers maintenance, repairs and renewal of its own connection and meter only where they are "due to normal wear and tear", so damage from something done on your side is not on that list. And section 5.505 puts a valve either side of your meter: "District shut-off valves are installed for the use of the District and will usually be found immediately adjacent to the street side of the meter", while "the District usually provides a valve on the Customer's side of each meter. This valve is for the Customer's use, and may be operated at the Customer's convenience." The street-side one is not yours to turn. One more thing worth knowing if this District answers for both your pipes: they divide in opposite places. Your water service is the District's to the meter; your sewer lateral is your property all the way to the District's main, connection included, with the District repairing the stretch under the street but not maintaining it. So a quotation for "the line to the street" means very different work depending on which pipe is meant. The sewer answer is on this District's own page in full.

Eastern Municipal Water District Administrative Code (revised 24 June 2026) - Title 5, Potable Water Service: sections 5.103(e) (definition of Service Connection), 5.104(c) (ownership of service connections and meters, the District's expense, and the customer's pipes downstream of the meter), 5.106(b) (post-meter piping and pressure devices), 5.505 (service connection shut-off valves) and 5.506 (Ownership of Service Connections)

What Eastern Municipal Water 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.

Eastern Municipal Water District has classified more of its service lines than most of California: 0.00% of its lines are unclassified, against 9.2% statewide.

Service lines reported: 165,510
Still unclassified: 0 (0.00%)

Where else this answer applies

Eastern Municipal Water District also supplies 2 other places with a page here, and the statement above is the same one that governs them: Menifee and Moreno Valley. 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.
165,510 is the whole of Eastern Municipal Water 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, and this system inspected less than most. Eastern Municipal Water District established 3.0% of its classifications by field inspection, against 22% across California; 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, San Jacinto gives the opposite answer to the one above:

San Jacinto answers this more directly than most, and it answers the half that usually goes unsaid. Section 13.20.260 of its municipal code establishes "that the maintenance, service, cleaning, repair, and replacement of sewer laterals shall be the sole responsibility of the property owner whose building or improvement is served by such laterals, and not the city", running "from the building or improvement that it serves to the connection at the public sewer in the public right-of-way". It then says the thing most codes leave to inference: "these obligations apply to the portion of the lateral on private property as well as any and all portions of such sewer laterals that lie within any public right-of-way".

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

Same trench, separate authorities, decided separately.
