Ground water or pipe water: the first test
Many wet basements are plumbing leaks wearing a groundwater disguise. A supply line, a water heater, a washer hose or a floor drain can soak a wall just as convincingly as soil can. Closing every fixture and watching the water meter tells you in minutes whether a pipe is involved.
For a wall that looks damp, tape a square of plastic sheeting to the concrete and seal all four edges. After a day or two, moisture under the plastic means water is coming through the wall. Moisture on the room side of the plastic means it is condensation. If the meter moves, start with leak detection before anyone cuts a slab.
Shallow groundwater, the canal and the irrigation season
The Utah Geological Survey says shallow groundwater, generally within 10 feet of the surface, can occur anywhere in Utah. It is more likely in low valley ground and near waterways, and levels shift with climate, seasonal precipitation and irrigation. It can also seep into basements and damage buried utilities. The Davis and Weber Counties Canal still runs through the area, and Clearfield's own water history is tied to canal water arriving in the 1880s.
No Clearfield-specific water table map turned up, so we cannot tell you your depth. What we can tell you is how to read your own house. Note whether water appears after a storm, in early spring, or all summer. Seepage that follows irrigation season rather than rain points to groundwater, and that points toward a drain and pump rather than gutters alone.

Signs your basement has a groundwater problem
Groundwater leaves a pattern. Look for the following before you call, and mention what you see.
- A damp line along the joint where the floor meets the wall
- White, chalky crust on block or concrete after the surface dries
- A musty smell that returns after cleaning
- Rust at the feet of the furnace or water heater
- A sump pit that runs in dry weather, or never runs in a wet spring
What a plumber can build to keep the basement dry
Waterproofing from a plumbing trade means controlling where water goes once it reaches the foundation. It does not mean sealing it out forever. Each of the options below manages the water in a different place.
Interior perimeter drain and sump pit
The crew breaks a channel in the slab along the wall, lays perforated pipe in gravel, and patches the concrete. The pipe slopes to a sump pit, where a pump lifts the water out. It works well for seepage at the floor joint and handles a rising water table without touching the yard.
Sump pump, check valve and backup
A pump that works only when the power does is half a plan. A battery backup or water-powered backup covers outages, which often come with the same storms. The Utah Geological Survey advises inspecting sump pumps each year before the wet season.
Backwater valve for floor drains
North Davis Sewer District says a backwater valve is required where the district manager decides one is needed, and the property owner installs and maintains it. A basement floor drain sits below the street, so sewage can rise through it. See sewer line repair for the line itself.
Matching the water source to the fix
This table is a starting map. The plumber confirms the source on site.
| Water source | Typical sign | Likely fix | When it makes sense |
|---|---|---|---|
| Rising groundwater | Seepage at floor joint | Interior drain and sump | Water persists after dry spells |
| Roof and surface runoff | Water after storms only | Downspouts and grading | Flat or backward slope at wall |
| Window well fill | Water under the window | Well drain and cover | Well collects rain |
| Sewer backup | Dirty water at the floor drain | Clear main, add backwater valve | Drain sits below street |
| Supply or heater leak | Meter moves, area warm or near fixtures | Repair the pipe or tank | Water source is pressurized |
Real basements often have two of these at once.

Clearfield City Code 10-1-4 on subsurface water says footings must sit at least two feet above the highest water table, or a foundation drain must be installed and routed to a positive drainage system. It also requires grading that moves water away from basement walls. The frost line in the city's design criteria is 30 inches.
About 39 percent of the city's 12,042 housing units date from before 1980, and the median home was built in 1989. Whether a given house has a foundation drain, and where it outlets, is something to confirm on site rather than assume. Ask us to check the pit and discharge before you buy a fix.
Where the pump water goes
North Davis Sewer District's ordinance bars groundwater sump discharges from the sanitary sewer, so never plumb a sump into a floor drain or sewer cleanout. Clearfield's storm water page says only storm water belongs in storm drains. The city site has no sump pump guidance, so confirm any street or curb discharge with Clearfield Public Works.
Winter matters here. With about 121 nights a year at or below freezing in Ogden-area normals, an exposed discharge line can ice up and push water back into the pit. A sump pump repair visit can add a freeze-safe outlet and extend it away from the foundation.
Radon and mold after a wet basement
Opening a slab for drains is a good moment to think about radon. Davis County Health Department, based at 22 S State Street in Clearfield, offers free seasonal radon tests with sign-up from October 1 to March 1. The EPA action level is 4 pCi/L, and the state says about 1 in 3 Utah homes tested high.
Mold needs the other half of the checklist. The CDC does not recommend routine mold sampling, and porous items that stayed wet for 24 to 48 hours usually should go. Never mix bleach and ammonia while cleaning.
What decides the cost of basement drainage work
No fair number exists before someone sees the basement. These factors drive the total.
- Length of drain run
- A single wall differs from a full perimeter, and each added foot means more concrete cut and patched.
- Pit and pump
- Pump capacity, a second pump, and a battery backup all change the equipment list.
- Discharge route
- A short run to daylight is simple, while a long buried line or a freeze-safe outlet adds work.
- Finished space
- Carpet, framed walls and built-in cabinets along the wall add removal and restoration time.
- Permits and testing
- Permit rules vary, so ask the Clearfield City building department, and a radon test may be worth adding.
Homeowner policies often exclude seepage and groundwater, and may cover sudden, accidental pipe discharge instead. Sewer or sump backup is commonly an optional endorsement, so read your policy before filing.

When this is not a plumbing job
A bowing wall, a stair-step crack or a horizontal crack is a structural question for an engineer or foundation contractor. A plumber cannot lower the water table or fix a settling footing. Exterior excavation, regrading and window well replacement are also outside most plumbing work.
If water is coming in right now, the first job is pumping it out and finding the source. Call the line, which is open 24/7, and we will start there. Homes in Layton and Syracuse reach the same dispatch.
Basement questions we hear in Clearfield
How can I tell if basement water is groundwater or a plumbing leak?
Close every fixture and watch the water meter for a few minutes. If it moves, a pipe is leaking. If it stays still and the dampness follows storms or irrigation, groundwater is the better suspect. The plastic sheet test on a damp wall helps confirm which.
Does a sump pump alone waterproof a basement?
No. A pump removes water that reaches the pit, but without a drain to route water into it, seepage at the walls can keep spreading. A pump plus an interior drain and correct discharge is the full system.
Can sump pump water go into my basement floor drain?
No. North Davis Sewer District bars groundwater sump discharge from the sanitary sewer. Plumb the pump to an approved outlet away from the foundation. For street or storm drain discharge, check with Clearfield Public Works first.
Do you do exterior excavation or foundation repair?
No. A plumber handles interior drains, pits, pumps, valves and discharge lines. Excavated membranes, cracks that move and bowing walls belong to a foundation contractor or structural engineer.
When is the best time of year for drainage work?
Before the wet season. Utah Geological Survey guidance is to inspect and maintain sump systems annually ahead of spring and irrigation season. Interior work can happen any month. A pit that fails in April is a harder call than one tested in October.
Should I test for radon before or after basement work?
Test before so you have a baseline, and again after, since slab work can change air movement. Davis County Health Department offers seasonal tests. Contact them directly to confirm current sign-up dates and availability.
