Water damage help across the South Bay
Four places, three water suppliers and four permit offices. Pick the town your home is in, or send a request from here.
Why each town has its own page
Drying out a house works the same way on either side of a city line. The water comes out, the structure is dried with dehumidifiers and air movers, and whatever stayed wet too long is cut out and replaced. What changes from one town to the next is everything around the job: which agency reads your meter, who owns the sewer main in the street, and which office issues the permit when the walls go back up.
This site began with Chula Vista, and Chula Vista has no separate town page because the home page is its page. Eastlake and Otay Ranch are Chula Vista neighbourhoods and are covered there too. Read water damage restoration in Chula Vista for the city itself. National City, Bonita and Imperial Beach each have a page written from their own agencies’ published rules.
Water, sewer and permits, town by town
This is the table to check before you phone anyone. It comes from each agency’s own pages, read in September 2026.
| Town | Water supplier | Sewer main | Repair permits |
|---|---|---|---|
| Chula Vista | Sweetwater Authority in the west and centre, Otay Water District in the east | City of Chula Vista; the lateral is the owner’s | City of Chula Vista |
| National City | Sweetwater Authority | City of National City, billed with property taxes | City of National City |
| Bonita | Sweetwater Authority and Otay Water District both name it | The published sources disagree; check your bill | County of San Diego (unincorporated) |
| Imperial Beach | California American Water | City of Imperial Beach | City of Imperial Beach |
Two things in that table catch people out. Imperial Beach is not on Sweetwater at all, so its leak and high-bill rules come from California American Water. And Bonita is not a city, so a rebuild there is permitted by the County, whichever company does the work.
