Who owns the water service line in Woodside, CA
The utility owns the service pipe, the curb stop, the meter and the meter box. The customer owns the piping past the meter - and the curb stop, which folklore treats as the boundary, is expressly the utility's. This is California Water Service, Bear Gulch District's own statement.

Why, and what to do
Where the responsibility divides
- California Water Service, Bear Gulch District
- The utility's CPUC tariff states that "the service pipe, curb stop, meter, and meter box furnished by the utility at its own expense and located wholly or partially upon a customer's premises are the property of the utility" - so the run from the main, the fitting at the curb, and the meter itself are all the utility's, even where they sit on the customer's land.
- The property owner
- The piping from the meter onward. The tariff makes this the customer's own job as a condition of getting service: they must "furnish and lay the necessary piping to make the connection from the service connection to the place of consumption" and must "keep such piping in good repair" (section A.2.a). Cal Water puts the same line to householders in plainer words on its help page "Who is responsible for making repairs?": "Property owners are responsible for repairs to plumbing on their side of the water meter." The same page pairs that with "Cal Water is responsible for repairs within the distribution system", which does not say whether the pipe running to your meter counts as part of that system - so if the leak is on the street side of the meter, that is the sentence to put to them.

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 95% of Woodside's land inside the boundary it maps for California Water Service, Bear Gulch District. Within the same city limits it also maps "CITY OF REDWOOD CITY" (3%). A share of land is not a share of homes: open space counts the same as a dense block. Measured 2026-09-11.
- Unclassified means nobody has established what the pipe is made of. It does not mean lead was found.
- 19,291 is the whole of California Water Service, Bear Gulch District'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. California Water Service, Bear Gulch District established 0.0% 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, Woodside says:
A cleanout at the property line decides this one. The Town maintains the run between that cleanout and the public sewer where a conforming one has been installed; without it the owner has the whole length, building to main. Every building sewer in Woodside is required to have one.
Your sewer lateral is yours to the cleanout; your water line stops being yours at the meter.
