Who is responsible for which part
In Moorpark, Ventura County Waterworks District No. 1 keeps the service connection and the meter, and stops at the meter. Its rules provide that "All service connections, water meters, detector check valves, and housings installed by the District shall be maintained at its expense", and that "The District's control and responsibility shall end at the customer's side of the meter." This is Ventura County Waterworks District No. 1's own statement.
- Ventura County Waterworks District No. 1
- The service connection from the main, the meter and its housing, maintained at the District's expense. "The District will furnish, set, and maintain all meters."
- The property owner
- Everything on the customer's side of the meter. "All piping and appurtenances installed by the customer on the customer's premises shall remain the property of the customer and the maintenance thereof shall be the customer's sole responsibility."

Ventura County Waterworks Districts, Rules and Regulations (Board approved 26 March 2024)What Ventura County Waterworks District No. 1 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.
Ventura County Waterworks District No. 1 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 Moorpark's land inside the boundary it maps for Ventura County Waterworks District No. 1. Measured 25 Sep 2026.
- Classified does not mean inspected. Across California only 22% of service lines were established by field inspection; most of 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, Ventura County Waterworks District No. 1 gives the opposite answer to the one above:
In Moorpark the owner keeps the whole side sewer, the fitting at the main included. Ventura County Waterworks District No. 1's rules provide that "The owner shall be responsible for maintaining the side sewer from the building connection to the public sewer line connection", and that "All connections, including the wye or saddle at the sewer main and lateral, shall be maintained at the expense of the property owner."
Your sewer lateral is yours to the main, fitting included; your water line stops being yours at the meter.
