As a homeowner receiving water or sewer services by the Department of Water Resources (DWR), you are responsible for the water and sewer systems inside your home and underground to the point of connection with the county system. This connection is made at the meter for the water line and at the sewer stub for the sewer line. Your sewer lateral, water service lines, backflow preventer, sanitary backwater device, and plumbing system all belong to you. If you have a septic system for wastewater treatment, that entire system is your responsibility.
Refer to the illustration below to get a better idea of what belongs to you and what parts of the system are managed by DWR. You can find out more about each topic using the dropdown selections below.
