The documents this answer is built on

Who is responsible for which part

Twentynine Palms Water District owns and maintains the service connection and the meter, through the valves just past it. Section 5.05.240 provides that "The service connection and meter are the property of the district", and section 5.05.260 that "The service connection, including the meter and meter box, will be repaired and maintained by the district at its expense". This is Twentynine Palms Water District's own statement.

Twentynine Palms Water District
The service connection, the meter and the meter box, and the pipes and fixtures up to and including the customer valve and check valve - District property, repaired and maintained at its expense.
The property owner
"All pipes and fixtures beyond the check valve shall be owned and maintained by the property owner."

What else is worth knowing

The line is the check valve just downstream of the meter. Damage caused by the customer, or the customer's family, guests or agents, is repaired by the District at the customer's cost, and "The district is not responsible for the installation or maintenance of water lines extending beyond the discharge end of the service connection." The District serves nearly all of Twentynine Palms, but check the name on your water bill.

What Twentynine Palms 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.

Twentynine Palms 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 Twentynine Palms' land inside the boundary it maps for Twentynine Palms Water District. 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. 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

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.
