Much of Bloomington is not on municipal sewer, and many homes use a private onsite wastewater system, so where a drain clog sits depends on how your home is served. A plumber can clear the drain lines either way. Call the number on this page to be connected with a local plumber in Bloomington.

How Bloomington drains are different
Bloomington is an unincorporated community between Fontana, Rialto and the Riverside County line. Parts of it remain semi-rural, with residents keeping animals, while warehouses have replaced some older homes. Much of Bloomington is not on municipal sewer; properties use private onsite wastewater systems, and which addresses are sewered varies. Knowing which one you have is the first step in sorting out a backup.
On a sewered property, the line from the house to the public main is private, and a plumber clears it the usual way. On a home not on municipal sewer, the house drains feed a private line to the onsite system's tank. A clog in the house or in that line is plumbing work. If every drain slows at once and the line itself is clear, the problem may be in the onsite system, which calls for a specialist in those systems. A plumber can tell you which side of that line the trouble is on.
West Valley Water District supplies water to Bloomington; its water is chlorinated and blended from groundwater, Lytle Creek surface water and State Water Project water. Permits for any repair go through San Bernardino County Land Use Services, Building & Safety, since there is no city building department.
Sewered home vs onsite system
| What you notice | Sewered property | Not on municipal sewer |
|---|---|---|
| One fixture slow | Local clog in trap or branch | Local clog in trap or branch |
| All drains slow together | Main line or lateral | Line to the tank, or the onsite system |
| Odor or wet ground outdoors | Cracked lateral | Line or onsite system needs checking |
| Backups after heavy rain | Damaged lateral | Saturated ground around the system |
Signs to act on
- Water rising in a tub or shower when other fixtures drain
- Toilets that gurgle or drain slowly throughout the house
- Sewage odor indoors or in the yard
- Soggy ground along the path of the drain line
Timing notes
Occasional heavy winter storms can soak the soil, which slows drainage on homes with onsite systems and exposes cracks in older sewer laterals. Grease is hard on both kinds of system, so keep it out of the kitchen sink. A single slow fixture can wait for a weekday appointment, which usually costs less than an after-hours call.
