Who owns the water service line in Campbell, CA
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.

Why, and what to do
Where the responsibility divides
- 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 San Jose Water Company 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.
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%)
Where else this answer applies
San Jose Water Company also supplies one other place with a page here, and the statement above is the same one that governs it: Saratoga. Each of them settles the sewer lateral separately, often under a different authority from this one.
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.
- The State's service area map puts effectively all of Campbell's land inside the boundary it maps for San Jose Water Company. Measured 2026-09-11.
- 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 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, West Valley Sanitation District says:
The District owns and maintains the lower lateral - the part between the property line and the sewer main in the street - where an accessible property line cleanout exists.
Your sewer lateral is yours to the cleanout; your water line stops being yours at the meter.

- Why your two pipes disagree — the places where the sewer and water authorities contradict each other about the run beneath the road.
- Which water systems know what is buried — how much of each California system’s network the utility can actually identify.
