ELectro Scan Technology Finds Leaking Infrastructure Before & After Rehabilitation Projects
Sacramento, Calif. – May 10, 2016 – City councils, public works departments, and utilities may be replacing leaking sewer and water pipes with new pipes that leak as much – or more – than the old ones.
Recent studies also suggest that Closed-Circuit Television (CCTV) and other legacy inspection techniques may be causing engineers to design and implement rehabilitation strategies for the wrong pipes.
Those are the findings from a California-based company that has developed new technology that finds and measures defects in cement, concrete, plastic, and relined pipes that deliver or transport sewer, water, and natural gas.
With billions spent annually to fix crumbling infrastructure, a recent poll found that 46% of respondents encountered significant defects after rehabilitation.
“Today’s pipes are supplied within generally accepted industry specifications,” says Chuck Hansen, Chairman, Electro Scan.
“But, defects from improper installation and faulty service re-connections – not seen by current inspection techniques – often cause leaking pipes to be unknowingly accepted by utilities,” continues Hansen.
Problems are often not found until after a warranty expires.
Last week, Trenchless Technology magazine, a leading publication serving the underground infrastructure market, and Electro Scan Inc., conducted a webinar that highlighted a city that recently completed a 5,500-foot Cured-In-Place Pipe (CIPP) lining project.
Using Electro Scanning Inspection, it was found that 1,066 ft or 19% of the project had more leakage after rehabilitation.
“Defects not typically found, include bad service connections, cracks that go through a pipe wall, defective joints, and faulty point repairs,” states Henry Gregory, former Assistant Deputy Director, City of Houston and Special Advisor to Electro Scan.
The new technology uses a focused low voltage current to evaluate 360-degrees of a pipe wall to find and measure openings that provide a clear pathway through a pipe.
Results are available in minutes on a cloud-based application.
Equipment can be purchased from the Company and added to existing CCTV trucks or vans, with services offered either by the Company or Authorized Partner.
