Your Bill Names Your Agency
The Water Authority sells water wholesale; it does not send bills to homes. Your retail agency does, and it is the one to call for a meter leak or a main break. Sewer service can be a different agency again. The city guides on this page name the provider for each place.
Hillsides, Coast and Older Neighborhoods
- Expect scale in water heaters and fixtures.
- Near the coast, salt air corrodes hose bibs and water heater fittings.
- Hillside homes need a working pressure regulator.
- Older neighborhoods have clay sewer laterals with roots; a camera inspection shows their condition.
