Underground Water Leak Detection in Marietta, GA
Underground water leak detection is the process of locating leaks in buried water lines using diagnostic testing before unnecessary excavation begins.
A leaking underground water line can waste water without leaving an obvious clue about where the pipe has failed. You may notice a higher water bill, reduced pressure, unusually wet soil, or water surfacing somewhere in the yard, but the visible symptom may not be directly above the leak.
Georgia Water Leak Detection provides underground water leak detection in Marietta, Cobb County, metro Atlanta, and nearby areas. We use professional diagnostic equipment to narrow down buried water-line leaks before unnecessary digging begins.
Instead of excavating along a line hoping to find the problem, the objective is to determine where the water is escaping first.
Call (470) 454-5051 if you suspect an underground water leak.
What Are the Signs of an Underground Water Leak?
Common signs of an underground water leak include unexplained water usage, a moving water meter when fixtures are off, reduced pressure, saturated soil, standing water during dry weather, and unexplained wet areas outside.
Other possible signs include:
- Water surfacing near a driveway, walkway, foundation, or landscaped area
- Unusually green or fast-growing vegetation in one location
- Soil erosion or soft areas
- The sound of water when no fixture is running
- Recurring exterior moisture
A visible wet area can help establish that something is wrong, but it does not necessarily identify the exact failure point. Water can move through soil and follow the path of least resistance before reaching the surface.
How Do Professionals Find Underground Water Leaks?
Professional underground leak detection can use plumbing isolation, pressure testing, acoustic listening equipment, and other diagnostic methods to narrow down where water is escaping from a buried line.
The appropriate process varies by property, pipe material, plumbing configuration, and suspected location
Isolate the Water Line
Testing different sections of the plumbing helps determine whether the suspected buried line is actually losing water.
Pressure Test the Line
Pressure testing helps determine whether an isolated underground water line holds pressure as expected. Pressure loss can provide evidence that water is escaping somewhere along the tested section.
Listen for the Leak
Acoustic underground leak detection uses specialized listening equipment to identify sounds and vibrations produced by water escaping from a pressurized buried pipe. Technicians can compare those signals at different points along the suspected route to help narrow down the failure location.
Narrow Down the Location
Information from isolation, pressure testing, acoustic signals, and other appropriate diagnostic methods can be considered together to identify the suspected failure point.
Once the location has been narrowed down, excavation can be directed toward the area that requires attention rather than using digging as the search method.
How Can You Tell If the Main Water Line Is Leaking?
If the water meter continues registering usage after known water-using fixtures and appliances have been turned off, a hidden leak may be present somewhere in the plumbing system.
The next challenge is determining whether the water loss is inside the building, beneath the slab, or somewhere along a buried exterior line.
Professional isolation and testing can help narrow down that distinction.
For leaks that may be inside the property, see our water leak detection service.
Can an Underground Leak Be Found Without Digging Up the Yard?
Yes. Professional leak detection can often locate or narrow down an underground water leak before excavation begins.
A damaged buried pipe may ultimately need to be exposed for repair. The goal is not to eliminate every possibility of digging. It is to avoid excavating multiple areas simply to search for the problem.
When the suspected location is identified first, excavation can be more targeted.
This is particularly valuable when water lines run beneath landscaping, driveways, walkways, parking areas, or other finished surfaces.
Why Can Water Appear Far Away From an Underground Leak?
Water from an underground leak can travel through soil, utility trenches, and other paths before reaching the surface, so the visible wet area may not be directly above the damaged pipe.
Once water escapes, it can follow the path of least resistance, travel along the outside of a pipe, or collect in a lower area.
A puddle or saturated patch should therefore be treated as evidence of a problem, not automatically as the place to dig.
Professional leak detection looks for evidence from the plumbing line itself rather than relying solely on where water becomes visible.
Is an Underground Leak the Same as a Slab Leak?
No. An underground leak generally involves a buried water line outside or away from the building’s concrete slab, while a slab leak involves plumbing beneath or within the concrete foundation.
Both are concealed leaks, and some diagnostic principles overlap, but the pipe location, access, testing circumstances, and potential repairs are different. If the suspected problem is beneath the building’s concrete foundation, see our slab water leak detection service.
Why Should You Locate an Underground Leak Before Excavation?
Locating the suspected leak before excavation helps direct digging toward the area most likely to contain the damaged pipe instead of opening multiple areas to search for it.
A buried water line may run a considerable distance across a property.
Professional detection can help answer:
- Is the buried line actually leaking?
- Which line is affected?
- Where does testing indicate water is escaping?
- What area is likely to require access?
- Is the problem underground or somewhere else in the plumbing system?
Those answers provide a more informed starting point for repair.

Why Choose an Experienced Underground Leak Detection Team?
Buried leaks can be difficult to locate because the pipe cannot be seen and surface water may appear away from the actual failure.
Georgia Water Leak Detection has 16 years of experience locating hidden water leaks throughout Marietta and metro Atlanta.
Our team of 20+ plumbers and managers uses professional diagnostic equipment to investigate buried water lines and narrow down suspected leak locations before unnecessary excavation begins.
We are licensed and insured, provide same-day service when scheduling permits, and offer 24-hour emergency service for urgent leak situations.
Do Commercial Properties Need Underground Leak Detection?
Yes. Commercial properties can develop leaks in buried water lines serving buildings, facilities, and other areas of the property.
An unexplained increase in commercial water consumption may require different sections of the plumbing system to be isolated before the source can be identified.
Our commercial leak detection service is designed for business owners, building owners, property managers, facility managers, and other commercial decision-makers dealing with hidden water loss.
What Happens After an Underground Leak Is Located?
After the suspected underground leak is located, the findings can be used to determine where access is needed and what repair approach is appropriate.
The repair depends on the pipe, failure, location, accessibility, and surrounding surface. A problem beneath open landscaping presents a different access situation than a line beneath a driveway or another finished area.
Georgia Water Leak Detection provides both leak detection and repair services. When we perform the repair, the detection fee is waived.

Underground Water Leak Detection FAQs
Here’s what people ask us most about underground leaks, straight answers first.
Possible signs include unexplained water consumption, a moving water meter when fixtures are off, reduced pressure, saturated soil, standing water during dry conditions, and unexplained wet areas outside.
Yes. A leaking pressurized water line can continuously lose water even when you are not intentionally using it.
Yes. Professional testing can often narrow down the suspected leak before excavation. Digging may still be necessary to access and repair the damaged pipe, but the goal is to identify where to dig first.
Water can travel through soil, trenches, and other paths underground before reaching the surface. The visible wet area may therefore be different from the actual pipe failure.
Testing may include isolating the affected plumbing, pressure testing, acoustic listening equipment, and other appropriate diagnostic methods. Information from these tests is used together to narrow down the suspected location.
Yes. We provide commercial leak detection for businesses and commercial properties, including investigation of suspected buried water-line leaks.
