Who owns the water service line in Corona, CA
The City's Utilities Department maintains the pipe from the main to the meter and the meter itself, and the customer maintains everything after it. Section 13.14.090(C) provides that "The service connection extending from the water main to and including the meter shall be maintained by the Department, and all pipes and fixtures extending or lying beyond the meter including the gate valve or ball valve shall be installed and maintained by the customer". This is Corona's own statement.

Why, and what to do
Where the responsibility divides
- Corona
- The service connection from the water main up to and including the meter. Section 13.14.010 defines that connection as "the tapping of water mains and the laying of pipes from the main to the curb-line, and the setting of the meter and meter vault", and section 13.14.090(A) requires that "Meters shall be set on public property" - so on an ordinary lot the whole of the City's length sits outside your boundary.
- The property owner
- Everything beyond the meter, starting with your own valve. Section 13.14.090(B) requires that "A gate valve or a ball valve shall be equipped on the outlet side of the meter for the customer's use", and subsection (C) makes that valve and every pipe and fixture beyond it the customer's to install and maintain.
- What else is worth knowing
- Use your own valve and leave the City's alone. The curb-cock on the inlet side of the meter "shall be for the exclusive use of the Department in controlling the water supply through the service lateral", and "Should the curb-cock or valve be damaged by the customer's use to an extent requiring repair or replacement, such shall be made at the customer's expense" - so a plumber who shuts the water off at the City's valve instead of yours can leave you with the bill. The code states the City's maintenance duty plainly but does not say in terms that it owns an ordinary service connection, which is why this is recorded as maintenance rather than ownership. And before relying on any of this, check the name on your water bill: Western Municipal Water District serves a part of the city, and if it bills you, its own rules govern your service rather than these sections.
What Corona 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.
Corona has classified less of its network than most of California: 41.4% of its service lines are still unclassified, against 9.2% statewide.
- 46,189
- 19,144 (41.4%)
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.
- Unclassified means nobody has established what the pipe is made of. It does not mean lead was found.
- Classified does not mean inspected, and this system inspected less than most. Corona established 0.0% 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, Corona gives the opposite answer to the one above:
Corona assigns the pipe plainly and defines it only by where it ends. Section 13.12.050 of the municipal code provides that "all house laterals, industrial connection sewers and appurtenances thereto now existing or hereafter constructed shall be maintained by the owner of the property served in a safe and sanitary condition and all devices or safeguards which are required by this chapter for the operation thereof shall be maintained in good working order". The code never defines a house lateral, so where the owner's run stops comes from what it runs to: section 13.12.020 defines a public sewer as "a main line sanitary sewer dedicated to public use".
Your sewer lateral is yours to the main; your water line stops being yours at the meter.
