Electro Scan expands products and services to Europe

Electro Scan Inc. (Electro Scan), developers of machine-intelligent multi-sensor leak detection technology for the water industry, has announced the initial shipment of its patented equipment to Europe for quality assurance testing of trenchless pipe rehabilitation. The company will be working with several new customers and partners testing full-length 360° ultraviolet (UV) and light-emitting diode (LED) cured-in-place pipe (CIPP) liners.

Availability of the company's non-acoustic multi-sensor in-pipe potable water leak detection solution, available as a service, is also driving growth in Europe.

“We are delighted to expand our state-of-the-art leak detection products and services throughout Europe,” stated Paul J. Pasko III, P.E., Vice President, International Business Development, Electro Scan.

The company’s expansion in Europe is managed through the company's EU-based subsidiary, Elektro Scan GmbH, which opened in 2014 and is headquartered in Frankfurt, Germany.

Prior to Electro Scan’s patented technology, contractors and municipal utilities typically used closed-circuit television (CCTV) cameras to 'accept' newly installed plastic and fibreglass pipes or relined older pipes. In many cases, the same company installing new CIPP liners has been responsible for performing post-CIPP inspection services, with many operators scoring defective liners with perfect scores regardless of a liner's actual condition.

The use of fibre optics to monitor curing temperatures for full-length liners was hoped to offer needed QA/QC for utility owners and CIPP suppliers. However, fibre optic’s inability to assess 360° of pipe wall surfaces, record only average temperatures at single points along a pipe, and inability to locate actual liner defects with accuracy or repeatability, limited its adoption and usefulness, especially compared to the added cost in time, material, and personnel.

Even artificial intelligence (AI) and machine learning, able to analyse frame-by-frame video of CCTV inspections, were unable to see if a liner has leaks. As such, a new technology that can independently assess and quantify leakage rates was needed. The lack of appropriate testing capabilities have oftentimes showed that CIPP liners may leak more after rehabilitation especially due to defective customer reconnections that often go unchecked and untested.

While traditional CIPP lining systems use epoxy resins cured with steam, hot water or ambient air, newer liners utilise glass reinforced materials that are cured using UV light as a heating source and now, specially-formulated resins may be heated with LED lighting to cure up to five times faster than other methods.

Electro Scan’s machine-intelligent technology provides unambiguous and unbiased pipe leak testing results – minutes after CIPP installation and curing is completed. Test results provide leak locations and severities for full-length, 360° pipes. Across dozens of CIPP suppliers, the company can consistently find and measure even the smallest pinholes.

A coupon sample of each CIPP liner installed in Germany is required to be tested at IKT laboratories, but since liner end pieces are not representative of full-length liner quality and does not provide water tightness testing results for each customer's reconnection, the same amount of rainwater can often enter through leaky customer connections, limiting the benefits from trenchless rehabilitation.
