Leak Surveys in Billings, MT

More Than 40 Years of Leak Detection without Destruction™

American Leak Detection of Montana provides leak surveys for municipal water purveyors, water districts, public works departments, and utility operators. Using advanced technology and non-invasive methods, we investigate buried water distribution systems to locate suspected leakage and document conditions for informed repair planning.

Billings operates a complex water system with approximately 500 miles of water main, 13 pump stations, 18 storage reservoirs, 32,000 water meters, and 4,700 fire hydrants. Across a network of that scale, water loss can involve mains, service connections, valves, hydrants, meters, and other buried assets. We bring more than 40 years of industry experience to a systematic approach built around Leak Detection Without Destruction™.

Field evidence can narrow the suspected loss area before excavation, but final repair targeting depends on conditions identified during repair.

Why Buried Distribution Systems Lose Water

Aging infrastructure, heavy usage, and poor original installation can contribute to pipeline cracking, shifting, or failure. Detection alone isn’t a permanent fix, but it can provide the location data and documented findings needed by the utility or its responsible repair team.

Buried leaks don’t always produce obvious surface water. Water can migrate through soil or follow underground utility corridors, allowing a pressurized line to lose water away from the failed section. Pipe material, depth, system pressure, available access points, and surrounding soil conditions all affect which detection method is appropriate.

The County Water District of Billings Heights has documented ongoing water-pipe leak investigations supported by independent leak detection and electronic or acoustic equipment. That local record reflects the practical need to investigate suspected losses methodically rather than relying only on visible discharge.

Assets a Municipal Leak Survey May Evaluate

A municipal leak survey evaluates a water distribution network rather than one visible plumbing fixture or an isolated interior symptom. We establish the project scope from the utility’s system layout, suspected loss area, available access, and operational objectives.

Potential survey points can include:

  • Water mains: Pressurized transmission and distribution piping within the defined survey area.
  • Service connections: Lines connecting the main to metered properties or other endpoints.
  • Valves and hydrants: Accessible system components that can provide testing or listening points.
  • Meters: Assets that help identify unexplained use or isolate discrepancies.
  • Pressure zones: Defined sections where pressure behavior can be compared and evaluated.
  • Pump and storage infrastructure: Relevant system assets considered when reviewing flow and pressure conditions.

Where the agreed project scope requires it, we can test on both sides of a meter for a fuller review. Our trained technicians document findings across the investigated portion of the network.

Signs a Utility May Need a Leak Survey

Non-revenue water is water that enters a distribution system but is never billed to a paying customer. It can reflect physical leakage as well as other system discrepancies, so field investigation should be guided by utility records and operating conditions.

Indicators that may warrant further investigation include:

  • Unexplained flow when expected demand is low.
  • Persistent or recurring changes in system pressure.
  • Meter movement when no known water use is occurring.
  • Differences between water production and billed consumption.
  • Recurring wet areas or water surfacing away from a known asset.
  • Customer complaints concentrated within part of the distribution network.

A lack of visible water doesn’t rule out a buried leak. Comparing readings over time and identifying unusual meter activity can help define where field testing should begin.

Our Municipal Leak Survey Process

We begin by reviewing the available system information and the utility’s reason for requesting a survey. Relevant materials may include distribution maps, asset details, meter or flow data, pressure information, access instructions, and known complaint locations.

Field testing is selected according to the pipe network, pressure, pipe material, access conditions, and suspected location. Depending on those factors, our investigation can use acoustic correlation, pressure testing, flow monitoring, or a combination of methods.

Acoustic Correlation

Acoustic correlation uses sensors placed at two points along a pressurized pipeline. The equipment compares how leak-generated sound reaches each sensor and uses that difference to calculate a likely leak location between the testing points.

Pressure Testing

Pressure testing evaluates a defined pipe section by applying controlled pressure and monitoring it for a drop. Results must be interpreted in the context of the isolated section, testing conditions, and configuration of the distribution network.

Flow Monitoring

Flow monitoring compares movement through the distribution system with consumption records or expected demand. Discrepancies can help identify areas associated with non-revenue water and guide more focused field investigation.

Documented Findings for Repair Planning

After the survey, we document the investigated network and relevant findings. Municipal survey documentation can identify confirmed leak locations, areas that warrant follow-up, and recommendations for addressing detected conditions.

A more precise location can help the utility narrow excavation, prioritize corrective work, and coordinate its own crew or contractor. Documentation can also support capital planning, insurance purposes, and applicable regulatory reporting. We explain the findings, available repair options, and related costs so decision-makers can evaluate the next step.

Repair responsibility depends on the project scope and the responsible repair provider. For residential plumbing needs outside a municipal distribution survey, separate service information explains when our own repair crew can handle the repair. A municipal leak survey remains focused on detection, documentation, repair recommendations, and coordination with the appropriate team.

The Operational Cost of Delayed Leak Investigation

Unresolved non-revenue water can increase water waste, raw water treatment costs, and pumping demands. The effect varies with leak size, pressure, soil conditions, pipe location, and the role of the affected asset within the water distribution system.

Continued underground leakage can also complicate maintenance planning, saturate nearby ground, and expand the area involved in later corrective work. Distribution-system leaks may create contamination concerns under certain operating conditions, which is another reason to investigate unexplained loss and pressure behavior promptly.

Early detection gives utility operators location data for prioritizing repairs and allocating maintenance resources. It doesn’t guarantee a particular outcome, but it can reduce uncertainty before excavation begins.

Plan a Documented Municipal Leak Survey

Provide your system type, suspected loss area, available records, and survey objective when requesting service. We can use that information to discuss an appropriate scope for your water distribution system.

Our approach combines non-invasive detection methods with documented findings and clear repair recommendations for municipal decision-makers.
