The documents this answer is built on

Who is responsible for which part

Yorba Linda Water District owns and maintains everything up to and including the meter; what runs downstream of it is the customer's. Its rules define offsite facilities as mains, valves, connections "and other appurtenances and property up to and including the Meter", and provide that "Offsite Facilities are owned and maintained by the District." This is Yorba Linda Water District's own statement.

Yorba Linda Water District
The service connection - "the pipe, tapping connection, valves, Meter, and other facilities by means of which water is conveyed from the District's water Main to the outlet side of the Meter" - owned and maintained by the District.
The property owner
The onsite facilities, which for water service "shall be those downstream of the Service Connection, which shall normally be the downstream end of the Meter." They "are owned and maintained by the Customer."

What else is worth knowing

The line is the outlet side of the meter, and for a fire service it is instead the isolation valve at the main. The District serves most of Yorba Linda, but not every address: Golden State Water Company's Placentia/Yorba Linda system serves a small part of the city - the State's register puts the District over about 93% of Yorba Linda and that system over about 3% - and if it bills you, its own rules apply - check the name on your water bill.

What Yorba Linda Water District 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.

Yorba Linda Water District 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 93% of Yorba Linda's land inside the boundary it maps for Yorba Linda Water District. Within the same city limits it also maps "GOLDEN STATE WC - PLACENTIA/YORBA LINDA" (3%). A share of land is not a share of homes: open space counts the same as a dense block. Measured 25 Sep 2026.
  • Classified does not mean inspected, and this system inspected less than most. Yorba Linda Water District established 5.0% 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 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

The sewer lateral leaving your property is a separate pipe, run by a separate authority, and who is responsible for it is decided separately. In many places the two answers are opposites.
