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".

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 89% of Saratoga's land inside the boundary it maps for San Jose Water Company. Within the same city limits it also maps "MT. EDEN MUTUAL WATER COMPANY" (3%), "SARATOGA HEIGHTS MUTUAL WATER COMPANY" (2%). A share of land is not a share of homes: open space counts the same as a dense block. 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
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, Saratoga says:
No single authority covers Saratoga: the City states that the sewer lines "are owned and maintained by Cupertino Sanitary District and West Valley Sanitation District". In Cupertino Sanitary District's area, that District makes you responsible for the house lateral, the cleanout and the point of connection to the street lateral, and states that it maintains and repairs the part in the street where there is an accessible, serviceable cleanout at the property line. In West Valley Sanitation District's area, about two thirds of the city, West Valley's code puts your side at the cleanout, "unless otherwise provided by district ordinance or policy", but another section names the connection at the public sewer as an end point too, without saying which applies when. West Valley's code says the part in the street "is owned by the district", and says both that the District "will maintain" it and, for laterals installed before 1 November 2026, that it "may continue" to, without reconciling the two. In West Valley's area, confirm with West Valley Sanitation District where your side ends and what it will do for yours.
Your sewer lateral is yours to the cleanout; your water line stops being yours at the meter.
