The documents this answer is built on

Who is responsible for which part

Santa Clara owns the water service connection all the way to and including your meter - even where it crosses your own land under an easement - and its Rules say it "will be repaired and maintained by the City at its expense". Your side is everything past it, "regardless of the location of the meters". That is the opposite of your sewer lateral here, which is yours the whole way to the main. This is Santa Clara's own statement.

Santa Clara
The service connection from the distribution line to the meter, owned and repaired at the City's own expense. The City's Water System Rules and Regulations provide that "the Service Connection, whether located on public rights-of-way or easements through private property, is the property of the City", and that it "including the meter and the meter box, will be repaired and maintained by the City at its expense except for damages as set forth in Section 13". The Rules define that connection to include "all or any portion of the water pipe and Appurtenances, including the meter, between the City distribution line and an individual Customer's system", and add that it "and all equipment Appurtenant thereto shall be the sole property of the City, and no part of the cost thereof will be refunded to the applicant".
The property owner
Everything past the service connection, wherever the meter happens to be. Section 13.A requires the Customer "at the Customer's risk and expense, [to] furnish, install and keep in good and safe condition equipment and suitable housings that may be required for receiving, controlling, applying and utilizing water, regardless of the location of the meters, or other City Equipment", and relieves the City of liability for loss or damage caused by the Customer's own installation, negligence or want of proper care.

What else is worth knowing

Two things are worth knowing. The first is that the City's expense does not cover damage you cause: section 14.G repairs and maintains the service connection at City expense "except for damages as set forth in Section 13", and section 13.A puts the risk and expense of the customer's own equipment on the customer, including loss or damage from "the negligence, want of proper care or wrongful act of the Customer or of any of the Customer's tenants, agents, employees, contractors, licensees or Permittees". The second is that moving things is at your cost: under section 14.C "meters or services moved for the convenience of the Customer will be relocated at the Customer's expense", and under 14.D a change in meter size is likewise at the customer's expense with the monthly rate adjusted afterwards. Note also that your two pipes divide in opposite places in Santa Clara - the water service is the City's to the meter, while your sewer lateral is yours all the way to the City-owned main - so a quotation for "the line to the street" means very different work depending on which pipe is meant.

What Santa Clara 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.

Santa Clara has classified more of its service lines than most of California: 0.00% of its lines are 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 99% of Santa Clara's land inside the boundary it maps for the city's own water system. Measured 25 Sep 2026.
  • Classified does not mean inspected, and this system inspected less than most. Santa Clara established 8.6% 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.

Your other pipe: the sewer lateral

For the sewer lateral, Santa Clara gives the opposite answer to the one above:

The whole pipe is yours, all the way to the City main, and the code says so in its definition: "each sewer lateral is owned by the entity that owns the property". No cleanout changes that. What a cleanout does change is what the City will do for you - with one at the property line, a City crew will check and clear the lower half at no charge; without one, the City says it "will not be able to assess the condition of the lower lateral to the main".

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

Same trench, separate authorities, decided separately.
