West Valley Water District serves Bloomington with a blend of groundwater and surface water, and its report shows hardness ranging from about 84 mg/L to 250 mg/L depending on the source. Because many Bloomington homes are not on municipal sewer, where the regeneration water goes is part of the decision. Call the number on this page to be connected with a local plumber in Bloomington.

Bloomington water and drainage
Bloomington is an unincorporated community between Fontana, Rialto and the Riverside County line. West Valley Water District names it among the communities it serves, although whether every address is in WVWD territory was not confirmed. WVWD blends groundwater from several basins, purchased Bunker Hill groundwater, Lytle Creek surface water and State Water Project water. Its report shows how much hardness varies by source: Lytle Creek water averages 150 mg/L, State Water Project water 84 mg/L, and groundwater roughly 140 to 250 mg/L. In grains per gallon, that is roughly 5 to 15. WVWD disinfects with chlorine.
Drainage is the other half. Much of Bloomington is not on municipal sewer and relies on private onsite wastewater systems, and which addresses are sewered varies. A standard softener sends salty regeneration water down the drain on a regular cycle. If your home uses an onsite system, talk with the plumber about how much water and salt the unit would add, and whether a high-efficiency model or a salt-free conditioner is the better fit.
Options compared
| Option | Sewered homes | Homes not on municipal sewer |
|---|---|---|
| Standard salt softener | Works well | Adds brine and water to the onsite system; discuss first |
| High-efficiency softener | Uses less salt and water | Smaller discharge per cycle |
| Salt-free conditioner | Less scale, no brine | No regeneration discharge at all |
| Under-sink RO | Drinking water only | Small reject stream |
Signs of hard water
- White crust on faucets and showerheads
- Spotty dishes and glassware
- Rumbling or popping from the water heater
- Scale in troughs and on outdoor hose fittings on lots with animals
Timing notes
Because WVWD blends sources, the water at your tap can change during the year, so test more than once if you are on the fence. If your home is connected to sewer at some point, a standard salt softener becomes a simpler choice, so it is worth knowing your status before you buy. On animal lots, keep troughs and outdoor spigots on unsoftened water; livestock do not need it and it only burns salt. Plumbing permits go through San Bernardino County Land Use Services, Building & Safety, since Bloomington is unincorporated. WVWD customer service is (909) 875-1804, option 3.
