Who is responsible for which part

In St. Helena the water pipe from the meter to the building belongs to the property owner, who must keep it in repair - including any part of it under the street - and the meter is the City's. The code defines the private water service as the connection, pipe or lateral serving a property "up to but excluding the water meter", and section 13.04.075 provides that "The private water laterals are the property of the property owner and are not part of the public water service system." This is St. Helena's own statement.

St. Helena
The public water service - the connection between the meter and the City's distribution system, "including the water meter and the meter box or vault" - which the code makes part of the public water service system of the City-owned water enterprise. Water meters "shall remain at all times the property of the city and shall be maintained, repaired and renewed by the department", and they are installed "only in public streets or places". The code does not say in terms who repairs the pipe between the main and the meter.
The property owner
The private water service from the meter to the building. Each owner must, at the owner's expense, "inspect, maintain in good working order, repair and replace, as necessary, the private water service, including any portions that may lie within the public right-of-way", get the encroachment permits that work in the right-of-way needs, and install and maintain a shutoff valve inside the property line. The City's lead service line inventory page speaks of "the customer-owned side of the water service line, which is between the meter and structure."

What else is worth knowing

The line is the meter: everything on the building side of it is the owner's, and because meters are set in the street, part of the owner's pipe can run under the public right-of-way - that part is the owner's too, and work on it needs a City encroachment permit. The meter and its box are the City's. The code does not say who repairs the pipe between the main and the meter, so ask the City's Public Works Department before paying for work there. The State's register puts the City's system over about 95% of St. Helena's land; Woodland Ridge Mutual Water Company's service area covers a little over 1% of it, and if that company bills you, its own terms apply, not these. Not every address is inside a mapped service area, so check the name on your water bill.

What St. Helena 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.

St. Helena has classified less of its network than most of California: 23.7% of its service lines are still 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 95% of St. Helena's land inside the boundary it maps for the city's own water system. A share of land is not a share of homes: open space counts the same as a dense block. Measured 26 Sep 2026.
  • Unclassified means nobody has established what the pipe is made of. It does not mean lead was found.
  • 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, St. Helena says:

St. Helena puts the private lateral on the owner under the street as well, stopping just short of the fitting in the main. Section 13.20.075 provides that "Each property owner shall maintain, repair, and replace their private sewer lateral up to but excluding the connection fitting installed in the public sewer."

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

Same trench, separate authorities, decided separately.
