Who is responsible for which part

In Half Moon Bay, Coastside County Water District owns and maintains the service connection from its main to the meter, and the pipe past the meter is the customer's. The District's General Regulations define the service connection as "an assembly consisting of the District-owned pipeline from the water main to the outlet side of the water meter, the meter box, fittings, and water meter", and provide that "Said meters and service connections shall be maintained, repaired and renewed by the District when rendered unserviceable through ordinary wear and tear".

Coastside County Water District
The service connection: the pipeline from the main to the outlet side of the meter, the meter box, the fittings and the meter. The regulations provide that "All service connections and meters shall be and remain the properties of the District and shall not be altered or moved by anyone other than an authorized employee of the District." The District repairs and renews them when they wear out in the ordinary way.
The property owner
The pipe on the customer's side of the meter. The regulations require that "The owner of the property to be served shall install a control valve on the pipe between the District meter and the first fixture outlet on the premises", and where an unusually high bill comes from a leak on the customer's side of the meter, "it shall remain the responsibility of the customer." In high-pressure areas the customer must also fit and maintain a pressure regulator on the service line on the property. Separately, the regulations limit the District's liability: it is not responsible "for broken or damaged pipes beyond the District meter".

What else is worth knowing

The line is the outlet side of the meter: the meter, its box and the fittings up to that point are the District's. The District's repair duty covers ordinary wear and tear; where a repair to the service or the meter is made necessary "by the act or negligence of the customer, his family or employee", the regulations provide that "any expense connected with said adjustment, renewal or repair shall be charged to and collected from the customer." The State's register puts the District's system over about 82% of Half Moon Bay's land and no other system over any of it; the rest, about 18%, is ground inside the city limits that no published water service area reaches - not a rival utility, and not necessarily unserved.
