Who is responsible for which part

Chino names the owner's pipe and puts it on the owner in a sentence of its own. Section 13.04.175 provides that "The owner of each parcel of land that is served by a water lateral or a fire service lateral shall be responsible for the repair, maintenance, and replacement of those laterals", and section 13.04.010 defines the water lateral as the portion of a water line that is "located between the structure and the water meter at the edge of the public right-of-way". This is Chino's own statement.

Chino
The meter and the service line on the City's side of it, as property. Section 13.04.040(B) provides that "Meters and service lines are and shall remain the property of the city, and no refund shall be allowed if such service is discontinued or removed".
The property owner
The water lateral - the pipe from the meter at the edge of the public right-of-way to the building - for repair, maintenance and replacement.

What else is worth knowing

Three things are worth knowing. First, a fire service is different: the code defines a fire service lateral as the fire line "located between the structure and the water main line in the public right-of-way", and section 13.04.175 puts that on the owner too - so for a fire service the owner's pipe runs all the way to the main, not just to a meter. Second, the City's half is stated as ownership rather than as a repair promise; the code prices "perpetual maintenance of services and meters" for customers outside the city but never writes the duty out for customers inside it, so for a leak on the City's side of the meter start with the City without assuming what it has undertaken. Third, check the name on your water bill: small parts of the city are served by the Monte Vista Water District and by the state prison's own system, and their own rules govern there.

What Chino 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.

Chino 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 95% of Chino's land inside the boundary it maps for the city's own water system. Within the same city limits it also maps "MONTE VISTA WD" (4%). A share of land is not a share of homes: open space counts the same as a dense block. Measured 25 Sep 2026.
  • Classified does not mean inspected, and this system inspected less than most. Chino established 6.0% 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 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

The sewer lateral leaving your property is a separate pipe, run by a separate authority, and who is responsible for it is decided separately. In many places the two answers are opposites.
