Find the water source before you spend anything
Spending money on a drain system for a leaking supply pipe wastes it. Spending money on a pipe repair for groundwater seepage does the same. The order of work matters more than the product you pick.
| Source | How it shows | Simple test |
|---|---|---|
| Plumbing leak | Damp spot near a pipe, drain or water heater, grows without rain | Turn off all water, read the meter, see if it still moves |
| Groundwater seepage | Water at the floor and wall joint, worse after wet weather | Tape foil to the wall, check which side collects water |
| Condensation | Cold pipes sweat, walls feel damp in humid months | Foil droplets on the room side point here |
| Surface runoff | Water at window wells or one wall after rain or watering | Watch gutters, downspouts and soil slope during a storm |
If the meter moves with everything off, the leak is in a pipe. Leak detection covers how we locate it without tearing up the floor.
What a plumber can fix and what needs another trade
Plumber scope
- Interior drain channels that carry water to a pit
- Sump pit, pump, check valve and discharge line
- Window well drains and sump connections
- Supply, drain and water heater leaks inside walls and slabs
- Floor drains and backwater issues in the plumbing
Needs a different specialist
- Foundation cracks that are moving or widening
- Structural wall repair or bowing walls
- Exterior excavation and membrane work as a main strategy
- Grading, gutters and landscaping changes
- Mold remediation after prolonged moisture
We will say so plainly if the first problem is not ours. A good diagnosis saves you from paying for the wrong fix.
What Riverton ground can do to a basement
The Utah Geological Survey's Special Study 152 covers the Copperton quadrangle, which includes parts of Riverton. It maps shallow groundwater, which the study says can flood basements and other underground facilities. It also maps collapsible soils, which lose volume when wet, and expansive soils, which swell when wet and shrink when dry.
Collapsible soil can settle and strain buried pipes. Expansive soil can crack foundations and damage underground utilities. The study does not say which Riverton blocks sit on which type, so treat this as a reason to check your home, not as a verdict.
The practical takeaway: movement and moisture often go together. If you see new cracks or a drain line that has started leaking, tell us. A water problem and a settling problem can be linked.

Interior drains, sump pits and discharge
When groundwater is the cause, plumbers usually manage it from the inside. A drain channel runs along the base of the wall and carries water to a sump pit. A pump then lifts the water out through a discharge pipe.
Confirm the source
Meter test, moisture checks and a look at gutters, grading and window wells.
Open the slab edge
A channel is cut along the problem wall or walls, then trenched and graded.
Set the drain and pit
Drain pipe goes into the channel and slopes toward the pit, which gets a liner and a lid.
Install the pump
A pump, float and check valve are set, with backup or alarm if chosen.
Route the discharge
Water leaves the house through a pipe that terminates away from the foundation.
Discharge rules vary, so ask the Riverton building department before choosing a route. The city says a building permit is required for work on plumbing systems the code regulates. Our sump pump page covers the pump itself.
Window wells, downspouts and plumbing mistaken for seepage
Window wells fill with rain and irrigation runoff, and a well without a working drain acts like a bucket against your wall. Downspouts that dump at the foundation do the same. Fixing either may solve a damp wall without any digging inside.
Riverton has a secondary irrigation system, which the city turns on tentatively around May 1. A sprinkler line break or a head that sprays toward the house can soak one wall for weeks. A broken sprinkler line is often stoppable at the property's ball valve.
Plumbing leaks are the most commonly overlooked cause. A pinhole in a copper line or a failing drain joint can mimic seepage for months. If the dampness is near a bathroom, laundry or water heater, check there first.
What basement waterproofing costs
Length of wall affected
One damp corner is a smaller job than a full perimeter drain.
Floor type and finish
Finished basements cost more to open and restore than bare slabs.
Pump and backup choices
Capacity, batteries and alarms are separate equipment.
Discharge route
Longer routes, buried pipe and outside restoration add labor.
Diagnosis time
Finding a hidden leak first costs less than fixing the wrong thing.
Homeowners policies often cover sudden pipe bursts but usually not seepage, groundwater or wear, so check your policy. Call us for a clear price before work starts.
Rules and sources behind this page
According to Utah Geological Survey Special Study 152, the Copperton quadrangle, which includes parts of Riverton, maps shallow groundwater, collapsible soil and expansive soil. The study does not say which Riverton blocks fall inside the mapped area, so use it as a reason to find the water source before you pay for a fix.
Any drain or sump work follows the plumbing code Utah adopts. Utah Code 15A-2-103 adopts the 2024 International Plumbing Code (IPC) as the state plumbing code, effective July 1, 2026, with Utah amendments on top.
Waterproofing questions
Shut off all water in the house and watch your meter. If it still moves, the leak is in a pipe. If it holds still while the wall stays damp, groundwater or condensation is more likely.
No. We handle plumbing and water management. If a crack is wide or moving, we suggest you bring in a structural specialist.
Only if groundwater is the cause. A pump needs a pit and drain that collect water, and a source that is a leaking pipe will not stop. See sump pump repair and installation.
Yes. Cold pipes and walls collect moisture in humid weather. Foil taped to a wall helps tell the two apart, because drops on the room side point to condensation.
The Utah Geological Survey maps shallow groundwater, collapsible soil and expansive soil in parts of the Copperton quadrangle, which includes parts of Riverton. It does not say which neighborhoods, so a home-by-home look matters.
Riverton says a building permit is required for work on plumbing systems regulated by the code. Ask the building department what your specific job needs.
Yes. We also dispatch to Bluffdale and other nearby towns from our Riverton base.
