Water system customers are responsible for the water service line from the water meter to the house. The District is responsible for the water service line from the mainline in the street up to and including the water meter. If a pressure regulator is installed to adjust the water pressure on the property, the customer is responsible to perform periodic maintenance on this device. If you suspect a break on the Districts side of the meter, please call the District immediately.
Sewer system customers are responsible for their sewer line from their property line to the house, which includes the sewer "clean out" and "back-water valve." The back-water valve is installed to prevent any back up sewage in the district system from entering the customer's property. The back-water valve should be inspected and maintained periodically by a local plumbing service to ensure it is functioning properly. Review the Water Vs Sewer Systems Diagram here.
