Rainbow Municipal Water District provides sewer to only parts of its territory, so many Bonsall homes are not on municipal sewer and drain trouble may involve a private onsite system. A local plumber can clear indoor drains and the house line and help you sort out where the problem lies. Call the number on this page to be connected with a local plumber in Bonsall.
Bonsall conditions
Bonsall is an unincorporated community served by Rainbow Municipal Water District. Rainbow is the water provider for Bonsall and the Rainbow area plus parts of Vista, Oceanside and Fallbrook. It operates eight lift stations and about 60 miles of sewer main, but it has far fewer sewer customers than water customers, and its sewer reaches only parts of the district. Many Bonsall parcels are on a private onsite wastewater system instead. Knowing which you have changes who you call when the problem is beyond the house.
Rainbow's water is rated very hard, averaging 13.45 grains per gallon. Hard water leaves mineral film in fixtures and traps, which combines with soap and hair to slow bathroom drains over time. Kitchen lines collect grease no matter what the water is like, and on a private system grease is doubly unwelcome because it travels out to the tank.
On sewer or not: what changes
| Situation | On Rainbow sewer | Private onsite system |
|---|---|---|
| One slow fixture | Clear the fixture branch | Clear the fixture branch |
| Whole house slow | Main or lateral blockage likely | House line or the onsite system itself |
| Neighbors backing up too | Call Rainbow at (760) 728-1178 | Usually not shared; look at your own system |
| Who handles the outdoor line | Ask Rainbow where your portion ends | The owner, all the way to the tank |
Signs to watch
- Bathroom sinks slowing as mineral and soap film builds
- Toilets that need a second flush
- Gurgling in a tub when the washer drains
- Soggy or smelly ground along the outdoor line
- Drains that slow after heavy rain
- A toilet that runs slow only when the irrigation or washer is going
Timing and seasons
Winter storms can saturate the ground, which slows drainage for homes on private systems and can push extra water into sewer lines. Clear minor clogs before the rainy season and avoid heavy water use, such as several loads of laundry in a row, while the ground is soaked. Permits for any pipe replacement go through the County of San Diego, since Bonsall is unincorporated. When you call, mention whether the property is on Rainbow sewer, so the plumber knows how far the problem may reach. Edges of Bonsall can be served by other agencies, so check your bill if you're unsure.
