Electro Scan Inc. designs, manufacturers, and sells machine-intelligent multi-sensor in-pipe leak detection devices and provides Software-as-a-Service (SaaS) based cloud reporting. The company’s award-winning patented technology uses low voltage electric current to detect leaks independent of pressure, flow, pipe material, and site conditions in pressurized potable drinking water systems, force mains, and gravity sewers, without interrupting customer services. Based in Sacramento, California, the company has field offices in London, England, Frankfurt, Germany, Melbourne, Australia, and Toronto, Canada.


Our quality standards and years of service continue to offer some of the most talented field and technical personnel in the industry. Read more to view a full catalog of our products.

If a pipe leaks electricity, it will leak water. Focused Electrode Leak Location (FELL) unambiguously locates and measures, in gallons per minute, all potential leaks that are typically missed by CCTV. Bad joints, cracks, holes, fractures, bad service reconnections, and poorly cured liners leak but cannot be detected visually. FELL has become the choice for locating infiltration and certification of trenchless rehabilitation throughout the United States.

Electro Scan offers multiple multi-sensor products, including the TRIDENT probe and the DELTA probe. They each offer competitive advantages.

Find infiltration and certify cured-in-place pipe. Focused Electode Leak Location (FELL). Represents the industry’s first reliable, proven, and measurable way to provide unbiased pipe condition assessment without third party interpretation or operator coding. Let Flow Meters show key areas, and FELL show specific locations.

Find infiltration and certify cured-in-place pipe.


  • For years, global water utilities have battled the lack of precise leak locations, inability to determine leak severities in industry-accepted metrics like GPM, and numerous false-positive readings from acoustic data loggers, correlators, listening sticks, and sensors. The purpose of this webinar will be to re-set how leaks can be more accurately found and expressed in GPM to support CAPEX decisions and long-term pipeline reliability & sustainability. Instead of listening (acoustically), seeing (visually), or smelling (helium tracing), attendees will learn how machine-intelligent technology can automatically measure the size of holes, by combining Ohms’ Law, plus Torricelli’s Law.

  • This video shows Electro Scan’s award-winning Focused Electrode Leak Location (FELL) Technology for gravity sewer leak detection. The industry's first machine-intelligent probe that provides an unambiguous, unbiased, and uncontested surveys of leaks in gravity sewer and force mains. Representing the only worldwide supplier in compliance with ASTM F2550-13 (2018), California-based Electro Scan Inc. is now. recommended by leading engineers to be included in testing and certifying all pipe repairs, rehabilitation, and relining projects.

  • This video shows Electro Scan’s award-winning Focused Electrode Leak Location (FELL) Technology for pressurized water line leak detection. Electro Scan’s Delta probe is a multi-sensor machine intelligent leak detection probe capable of providing unambiguous, unbiased, and uncontested surveys of leak in pressurized water lines. With reports available within minutes, agencies can quickly and accurately locate and quantify defects in their distribution system. FELL technology is included in the AWWA m77 manual for condition assessment of water mains and is being utilized by agencies the world over.

  • After spending decades and millions of dollars rehabilitating sewer pipes across its service area, a large coastal utility embarked on a pilot pipe condition assessment program for 25,000 linear feet in areas prone to high unwanted infiltration rates.

  • Balfour Beatty was unable to determine why a new pipe installation, a 600mm (24 inch) diameter Cement Mortar Lined Ductile Iron, 170m (560ft) pipe length was unable to pass multiple hydrostatic pressure test. Using multiple above ground and in-pipe acoustic sensors, data correlators, data loggers, and listening sticks, no leak locations could be found.

  • Leaks found in 60 psi high density PE pipe by FELL in less than three hours. Acoustic and CCTV failed to find any leaks after more than a year of investigation. Read the full case study to learn more. 

  • It is estimated that nearly 75,000 miles of wastewater and water pipelines have been lined with Cured-In-Place Pipe (CIPP), with nearly $3 billion spent annually on the trenchless renovation method, worldwide. Recognizing the growing use of CIPP and inability of CCTV inspection to accurately or consistently certify trenchless rehabilitation as defect-free, this paper chronicles the emergence of new guidelines to test, certify, and accept CIPP lining projects, using Focused Electrode Leak Location (FELL) inspection.

  • In 2017, the Institute of Underground Infrastructure (IKT), Gelsenkirchen, Germany, utilized low voltage conductivity to test a variety of trenchless Cured-In-Place Pipe (CIPP) short-liners to locate and quantify leaks, several of which were utilized in a multi-million rehabilitation project in Kansas City, Missouri (USA).

  • Worldwide water utilities and smart cities are adopting new technologies to replace legacy technologies that have been the mainstay to assess existing pipe conditions and accept new installations as watertight. This white paper includes a detail review of existing assessment techniques, project findings, technology overview, and field results fom each project area included as part of Sydney Water’s trial project evaluation of FELL technology.
