Who is responsible for which part

Carpinteria Valley Water District operates and maintains the service line from the main up to and including the meter, and the customer has everything after it. The District states that "CVWD operates and maintains the pipe from the main up to and including the water meter. Our customer's responsibility begins after the water meter and continues through the property and into any buildings." This is Carpinteria Valley Water District's own statement.

Carpinteria Valley Water District
The service pipe from the main and the meter. The District calls this "the District-owned portion of the water service line", and its Rules and Regulations provide that "The District is responsible for the proper operation and maintenance of the water meter including the gasket on the customer side of the meter".
The property owner
Everything after the meter. "Piping and appurtenances including any shut-off or customer valve after the gasket and meter mounting hardware on the customer side of the meter are the customer's property and responsibility." Rule 24 has the customer "furnish, install and keep in good and safe condition" the apparatus for receiving the District's water, water lines included.

What else is worth knowing

The exact line is the gasket on the customer's side of the meter: the District keeps the meter and that gasket, and the customer's valve and pipe start after it. The rules also set a deadline: "All leaks, whether found by the customer or District personnel, must be repaired within 72 hours of identification." The State's register puts the District's system over nearly all of Carpinteria, but check the name on your water bill.

What Carpinteria Valley 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.

Carpinteria Valley 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 99% of Carpinteria's land inside the boundary it maps for Carpinteria Valley Water District. 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, Carpinteria Sanitary District says:

In Carpinteria, Carpinteria Sanitary District maintains the lateral under the street, from the property line to the main, where there is a cleanout at the property line, and the owner has the building sewer from the building to that point. The District's answer is that it "provides maintenance and repair of main sewers and lateral sewers within the public right of way, provided there is an accessible and serviceable cleanout at the property line", and that "Maintenance and repair of the building sewer, cleanout and point-of-connection to the District lateral are the responsibility of the property owner."

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

Same trench, separate authorities, decided separately.
