Near the Jordan River, Bluffdale basements can face high groundwater and hydrostatic pressure, so a failed or undersized sump pump is a common cause of wet floors and mold. Elsewhere in the city, storms and plumbing leaks cause most problems.
About Bluffdale
Bluffdale incorporated in 1978 and had 17,014 residents at the 2020 Census. It spans Salt Lake and Utah counties, takes its name from the bluffs and dales along the Jordan River, and borders Herriman, Riverton, Draper and Lehi, with Camp Williams to the south.
Groundwater Near the River
Bluffdale City identifies areas near Rose Creek and the Jordan River as the most flood-susceptible in the city, and notes that groundwater levels may be high near the river when flows rise. The city advises residents in those areas to make sure their sump pumps work and to keep landscaping and gutters draining away from the house. When saturated soil pushes water up through the slab or the floor-wall joint, finished flooring and the bottom of drywall stay wet — and mold follows.
High groundwater can push through slab cracks, and groundwater leak detection confirms it before you buy a drainage system.
Sump Pump Readiness
| Check | Why |
|---|---|
| Test by pouring water into the pit | Confirms the float and pump work |
| Battery or water-powered backup | Keeps pumping during outages, when storms hit |
| Check valve and discharge line | Stops water flowing back; keeps discharge away from the house |
| Pump age | Replace pumps older than 7–10 years before they fail |
| Sealed pit lid | Keeps moisture out of basement air |

Which County Are You In?
Bluffdale sits in both Salt Lake County and Utah County, with Camp Williams to the south and the Jordan River running through it. That split matters more than people expect. Health department rules for septic systems, some permit questions and the local agencies you call can depend on which side of the county line your home is on. Check your property tax notice if you are not sure.
Horse Properties and Larger Lots
Much of Bluffdale still has larger lots, horse properties and homes that predate the newer subdivisions. Irrigation on acreage, older basements with block or poured walls of different ages, and outbuildings with tack rooms or shops all add to the moisture picture. Older homes near the river often combine high groundwater with an older sump, which is the setup most likely to flood when power goes out during a storm.
When a Sump Alone Is Not Enough
Some Bluffdale basements near the river get water along the floor-wall joint on several walls, not just near the pit. That means the water is reaching the slab faster than the existing drain can carry it. Interior drain tile around the full perimeter gives that water a path to the sump before it reaches the floor, and a second pump or a battery backup keeps the system running when it is busiest.
Bluffdale's older and newer homes also differ in what they hide. Older basements may have block walls and patched floors where water finds old cracks; newer ones have finished drywall over poured walls, where the first sign of groundwater is often damp carpet along an exterior wall.
Groundwater Mold Needs a Two-Part Fix
- RemediateRemove moldy flooring and drywall, HEPA-clean and dry the slab and framing.
- Control the waterRepair or upgrade the sump system; consider interior drain tile if water enters at the floor-wall joint.
- Rebuild for moistureWaterproof flooring, a gap at the floor and moisture-tolerant materials in the lower level.

Frequently Asked Questions
Is Bluffdale in Salt Lake County or Utah County?
Both. Most of the city is in Salt Lake County and part is in Utah County, which can affect permits and septic rules. Your property tax notice shows which applies.
Do I need a battery backup sump pump in Bluffdale?
If your home is near the river or has had water at the floor before, yes. Power outages and pump failures during wet periods are the most common way these basements flood.
Why does my Bluffdale basement get wet when it has not rained?
Near the Jordan River, groundwater can rise when river flows are high. Water pushes up through the slab or floor joint, so a working sump pump matters.
Which county is Bluffdale in?
Bluffdale spans both Salt Lake County and Utah County.
Will a new sump pump stop mold?
It stops new water. Existing mold still needs removal, and the area must be dried before rebuilding.
