Who is responsible for which part

Signal Hill owns and keeps up the service connection and the meter, and the customer's side begins past the meter. Section 13.04.070 provides that "All service connections and all water meters installed by the department shall at all times remain the property of the city", and section 13.04.220 requires every consumer to install, "for his ordinary usage and at his own expense, a shutoff valve on the property side of the meter." This is Signal Hill's own statement.

Signal Hill
The service connection and the meter, owned by the City and in the charge of its water and power department. Section 2.48.020 gives that department "charge of the installation, maintenance, and operation of all" water mains, distribution lines and meters, "together with all other property and appurtenances used in connection with the operation of the municipal water and power system". Section 13.04.070 puts on the City "The expense of maintenance, repair, and renewal of such meters due to the wear of normal service", and charges to the consumer any expense "occasioned by any act, careless or otherwise, on the part of the consumer".
The property owner
The plumbing on the property side of the meter, starting with a shutoff valve there at the consumer's own expense. Section 13.04.260 puts on every owner or occupant "the duty to equip and maintain said premises with plumbing of such character and quality as to prevent the wasting of water", and lets the City shut off the service pending proper repairs if disrepair wastes water.

What else is worth knowing

The line is the meter. The code makes every service connection the department installs City property and puts the consumer's own valve on the property side of the meter; damage the consumer causes to the City's equipment is charged to the consumer. The State's register puts the City's system over nearly all of Signal Hill, but check the name on your water bill.

What Signal Hill 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.

Signal Hill 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 Signal Hill's land inside the boundary it maps for the city's own water system. Measured 26 Sep 2026.
  • Classified does not mean inspected, and this system inspected less than most. Signal Hill established 10.3% 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, Signal Hill gives the opposite answer to the one above:

Signal Hill writes no sewer ownership rule of its own and borrows the County's. Section 13.06.010 of its municipal code adopts Division 2 of Title 20 of the Los Angeles County Code, "as adopted, amended and in effect on July 27, 1989", as the Sanitary Sewer and Industrial Waste Code of the city. Inside that adopted division, section 20.24.080 provides that all house laterals "shall be maintained by the owner of the property served in a safe and sanitary condition", and section 20.20.130 defines a "house lateral" as "that part of the sewer piping within the street or right-of-way which extends from the property or sewer right-of-way line to a construction with the main-line sewer". The length the City's ordinance puts on the owner is the length under the road, and the City's own answer to the question is short: "Sewer laterals are the responsibility of the property owner."

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

Same trench, separate authorities, decided separately.
