Your lateral runs all the way to the main
In Norwalk, you look after the house lateral as the owner, including the part under the sidewalk and street. So if that stretch breaks, it’s yours to fix, not the city’s.
If your home has an old clay lateral, that’s worth knowing before the rainy season. Roots creep in at the joints over time, and a narrowed line can back up once winter storms push extra water into it. A camera inspection shows the condition of the whole line, including the part under the street.
Several water providers
Norwalk is served mainly by three water systems: the Norwalk Municipal Water System, Golden State Water and Liberty Utilities. The City of Santa Fe Springs also supplies part of the community. The city’s water page includes a map for checking which provider serves your address.
The city’s own system, the Norwalk Municipal Water System, has about 5,300 service connections and serves more than 22,000 residents in Norwalk and Artesia. If your bill comes from the city, that’s who to call about your meter or a leak adjustment.
Older homes, older supply lines
Like much of the area, Norwalk has many homes built before 1960 that still run on galvanized supply pipe. When pressure fades throughout the house and hot water turns rusty, a repipe is usually the lasting fix.
Before you call
Find your sewer cleanout if you can, check your bill so you know your water provider, and note whether one fixture or the whole house is affected. A plumber can take it from there.
