Bonsall's water and wastewater

Bonsall is an unincorporated community inside Rainbow Municipal Water District's service area, which also covers Rainbow and parts of Vista, Oceanside and Fallbrook. Every gallon Rainbow delivers is imported from the State Water Project or the Colorado River and treated upstream at Metropolitan's Skinner plant. The District's report classifies it as very hard: 230 mg/L on average, the same as 13.45 grains per gallon. That is a level where scale shows up on fixtures, inside tankless heaters and at the bottom of tank heaters.

For disinfection Rainbow relies on chloramines, with some areas occasionally moved to free chlorine. Neither is touched by a softener; taste is a job for a carbon filter.

Rainbow sewers only part of its territory, and many Bonsall parcels are not on municipal sewer. For those homes, the brine a softener discharges during regeneration goes to a private onsite wastewater system, which affects what kind of unit makes sense. Edges of Bonsall may be served by other water agencies, so confirm on your bill.

Timing notes

With water this hard, it pays to install a softener before replacing a water heater or tankless unit, so the new equipment starts clean. Irrigation season is a good time to make sure outdoor lines bypass the softener, since softening water for landscaping wastes salt and adds nothing for plants. If an older unit is already in place, ask the plumber to confirm its hardness setting matches Rainbow's published average rather than a guess from years ago. Bonsall is unincorporated, so permits go through the County of San Diego. For service questions, call Rainbow at (760) 728-1178.

Water Softeners & Filtration questions in Bonsall

How hard does water need to be before a softener pays off?

There is no fixed cutoff; water that keeps leaving scale on fixtures and heaters is usually worth treating. Rainbow calls its Bonsall supply very hard at 13.45 grains per gallon, which clears that bar easily.

Can a softener be used on a home not on municipal sewer?

Yes, with planning. Many Bonsall parcels aren't on sewer, and the brine discharge adds salt and water to the onsite system, so a high-efficiency unit or a salt-free option is often suggested.

Where does the softener's brine drain go?

Into the home's drain system through an air gap. On Rainbow sewer it goes to the public system; on a private onsite system, it goes there, which is why unit choice matters.

Does a softener help a water heater or tankless unit last longer?

In very hard water like Bonsall's, yes. It cuts the scale that settles in tank heaters and coats tankless heat exchangers.
