San Jose Water (SJW) Customer Service
The utility owns the service pipe, the curb stop, the meter and the meter box. The customer owns everything from the meter outlet coupling inward. This is San Jose Water Company's own statement.
- San Jose Water Company
- The tariff states that "the service pipe, curb stop, meter, and meter box furnished by or on behalf of the utility and located wholly or partially upon a customer's premises are the property of the utility". The utility's own "Who's Responsible for What?" page describes the same span in plain words, and in terms of upkeep rather than title: SJW "is responsible for the pipes that bring water from the water main located under the street, all the way to the meter outlet coupling".
- The property owner
- Everything past that coupling. The same page states that "customers are responsible for everything from the connection of their service line to SJW's coupling", itemising the service line from the meter to the house, the house valve, and all plumbing fixtures inside and outside. Its tariff makes it a condition of service that the customer "furnish and lay the necessary piping to make the connection from the service connection to the place of consumption" and "keep such piping in good repair".
What else is worth knowing

San Jose Water, Rule No. 16What San Jose Water Company 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.
San Jose Water Company has classified more of its service lines than most of California: 0.00% of its lines are unclassified, against 9.2% statewide.
- 236,341
- 0 (0.00%)
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 effectively all of Campbell's land inside the boundary it maps for San Jose Water Company. Measured 25 Sep 2026.
- 236,341 is the whole of San Jose Water Company'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. San Jose Water Company established 2.9% 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.
Where else this answer applies
This page also answers for Los Gatos and Monte Sereno, which take the same water answer as Campbell from San Jose Water Company and the same sewer answer from West Valley Sanitation District.
San Jose Water Company also supplies the place below, and the statement above governs it too:
It settles the sewer lateral separately, often under a different authority from this one.
Your other pipe: the sewer lateral
For the sewer lateral, West Valley Sanitation District says:
The District's ordinance code says "the lower sewer lateral is owned by the district" - the run from the property line cleanout to the sewer main in the street. On who maintains it, the code says more than one thing. It says the District "will maintain" the lower lateral and "is generally responsible for the maintenance, cleaning, inspection, repair, and replacement" of it. But for lower laterals and cleanouts installed before 1 November 2026, a further sentence reads "the district may continue to maintain, clean, inspect, and repair existing lower sewer laterals", on conditions, and the code does not say how these fit together. Where your side ends is not fixed either. The code's definition puts it at the cleanout, the cleanout included, "unless otherwise provided by district ordinance or policy", and another section names both the cleanout and the connection at the public sewer. Without an approved, accessible cleanout, the maintenance of the whole run to the main is yours. Confirm with the District where your side ends and whether it will maintain, repair or replace the rest before relying on it.
Your sewer lateral is yours to the cleanout; your water line stops being yours at the meter.
