Protecting Public Water Infrastructure with Precision Detection

Hidden leaks in water distribution systems can cause water loss, pressure problems, ground damage, and service disruptions. They can also complicate decisions about where to excavate. We provide municipal leak detection for St. Louis utilities and public-sector operators that need to narrow the search area and confirm leak locations before repair work begins.

As The Original Leak Specialist™, we use proprietary, non-invasive technology developed through more than 50 years of leak detection work. Our approach provides operators with actionable findings without relying on unnecessary exploratory excavation.

Municipal Water Systems & Public Infrastructure We Serve

We work with organizations responsible for public and shared water infrastructure. They may need support with a suspected leak, a system assessment, a water-loss investigation, planned excavation, or decisions about which infrastructure work to prioritize.

Municipal and public-sector clients may include:

Municipal water utilities
Public works departments
Regional water districts and authorities
City and county infrastructure management teams
Public schools and government facility operators
Parks and recreation departments
HOA communities with shared water distribution infrastructure

Each project is shaped by the system, available access points, operating conditions, and suspected location. We also work around operational schedules to minimize service disruption during detection activities.

Locate Underground Leaks Before Excavation

Underground water loss may surface far from the damaged line or remain hidden entirely. By investigating from above ground, we work to locate leaks in water distribution systems before excavation begins, giving maintenance teams a more focused area for repair planning.

Our technicians apply proprietary, non-invasive technology supported by ongoing training and research into detection methods. When the available evidence doesn’t confirm a precise location, we can identify suspected areas that warrant further evaluation rather than presenting an uncertain finding as confirmed.

When a Water Distribution System Needs Investigation

Operating data and field conditions may point to a hidden problem before water becomes visible at the surface. Detection may also be appropriate when a municipal team needs to narrow a repair area before committing labor, equipment, or excavation resources.

Conditions that can justify further investigation include:

Unexplained differences between water production and customer consumption data
Pressure changes without a known operational cause
Persistent wet areas or soft ground near buried infrastructure
Sinkholes or visible ground movement
Water surfacing away from the expected pipeline location
Recurring main failures within part of the distribution network
A suspected leak area that needs to be narrowed before excavation

These conditions don’t confirm a leak on their own. System records, pipe characteristics, field observations, access points, and operating data all help determine how the work should proceed.

Non-Invasive Detection Methods for Public Water Systems

No single method fits every distribution network. We select an approach based on factors such as pipe material, line layout, suspected location, background noise, access, and the system information available.

Acoustic Correlation

Acoustic Correlation compares leak-generated signals recorded at separate points along a pipeline. Differences in how those signals reach each sensor can help calculate the probable location.

Ground Micing

Ground Micing uses sensitive listening equipment at the surface to evaluate sounds associated with pressurized water escaping underground. Our technicians assess those acoustic signatures while accounting for site conditions and surrounding noise.

Flow Monitoring

Flow Monitoring evaluates movement through a system or defined area to identify patterns that may indicate water loss. Comparing inflow with recorded consumption can help operators investigate possible non-revenue water, meaning treated water that enters the system but isn’t reflected in billed consumption.

Written Findings for Compliance & Capital Planning

We provide written reports covering the methods used, confirmed leak locations, suspected areas that may require follow-up, and recommendations for the next stage of evaluation or repair coordination. This documentation can help a utility define contractor scope, prioritize repairs, and preserve a clear record of the findings.

The same records may support compliance documentation and capital planning, depending on the utility’s procedures and applicable jurisdictional requirements. Each operator remains responsible for determining which reporting obligations apply to its system or project.

Plan the Next Step for a Suspected Municipal Leak

We provide municipal leak detection for St. Louis utilities and public-sector operators that need to evaluate water loss, confirm a suspected location, or prepare for repair work. Share the available system information, site location, and operational concern so our team can discuss the appropriate detection scope.
