• Blame our fast food diets or restaurants’ negligence for what’s going down the drain. Whatever the cause, fats, oil, and grease (FOG) accumulation has become a pervasive problem for wastewater treat­ment plant collection systems.

  • Effectively managing hundreds of thousands of miles of sewer network is not an enviable task. And with ever changing industry regulation, stricter statutory targets, additional compliance and a growing abundance of technology, that task could easily be regarded as insurmountable. How can you ever know exactly what’s going on throughout your entire network? It’s impossible. Or is it?

  • This month our topic fits in well with a whole genre of music and it was hard to pick just one song to weave into this column, so I didn’t. The hits just kept coming to mind so consider this discussion of building pipelines in rock to be an homage to all things rock and roll!

  • The House Transportation & Infrastructure Committee is moving forward with a measure that would invest $3.7 billion in critical wastewater and stormwater infrastructure. These resources will help communities across the country struggling with sewage spills, inadequate sanitation, and destructive urban flooding.

  • There are a few current governmental policies that have impacted the construction cost of water and wastewater infrastructure over the last several years. Some are older policies that were established many years ago and some are newer policies that were implemented to help U.S. manufacturers compete in these markets against foreign manufacturers. There is some discussion now in Washington to implement more policies such as $15 minimum wage and revisions to the Made in America requirements for purchases using federal money, both direct and indirect.

  • Turning your water tap on only to be encountered by a terrible stench is arguably one of the worst ways to start your day. Your immediate reaction may be to assume that your water supply is contaminated, but there are myriad reasons why your household water has suddenly developed a pungent odor.

  • 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.

  • 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).


  • Xylem Wastewater Network Optimization: A Smart, End-To-End Wastewater Platform

    Sewer overflows are a growing problem for cities around the world. With more severe rain events expected due to climate change, solving this critical water challenge is more important than ever. Doing so affordably is even harder. Xylem Wastewater Network Optimization is a real-time decision support system (RT-DSS) utilizing smart sewer technology that gives utilities a better view into the performance and capacity utilization of their existing sewer system assets. This allows utility leaders to optimize levels of service while saving money, reducing risk and protecting the environment.

  • Pikeville, Kentucky Medical Center Leak Found Despite Ambient Noise

    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. 

  • New Standard For Sewer Lateral Condition Assessment

    Find infiltration and certify cured-in-place pipe.

  • New Standard For Sewer Main Condition Assessment

    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.

  • Machine-Intelligent Leak Testing Of Underground Pipes

    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.


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.
