Who is responsible for which part
Las Virgenes Municipal Water District owns the service connection and the meter and pays for their normal upkeep; everything downstream of the meter is the customer's. Section 3-2.105 provides that "Service connections and water meters installed or accepted for use by the District are the property of the District", and that "The expense of maintenance, repairs, and renewal of such service connections and meters, due to normal wear and tear, shall be borne by the District." This is Las Virgenes Municipal Water District's own statement.

What else is worth knowing

Las Virgenes Municipal Water District Code, section 3-2.105What Las Virgenes Municipal Water District 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.
Las Virgenes Municipal Water District 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 98% of Calabasas' land inside the boundary it maps for Las Virgenes Municipal Water District. Measured 25 Sep 2026.
- 21,241 is the whole of Las Virgenes Municipal Water District's reported inventory, not this city alone. The State's file records no city for these lines, so they cannot be counted per city.
- Classified does not mean inspected, and this system inspected less than most. Las Virgenes Municipal Water District established 6.8% 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.
