“Cleaning and lining a water main is like scouring the interior wall with rough pads, then ‘refinishing’ the walls with a thin cement-mortar coating,” explained John Marciszewski, a business development director for Echologics®. “The process removes accumulated tuberculation and corrosion, but also reduces the original pipe wall thickness. Our ePulse® technology can detect if the process has severely degraded the structural integrity of the pipe to the point where it can no longer withstand the stress of high operating pressures under load.”
A major water system operator commented that “Echologics' technology is now a proven tool in our toolbox and replacing pipe is not a ‘green’ alternative — and on a yearly basis we are definitely saving hundreds of thousands of dollars using ePulse technology. Capital is dear, and we have many needs. Utilizing new technologies like these enables understanding of where to apply our capital resources most effectively, and where they will do the most good for our customers.”
The key to success is to select a water main condition assessment technology that is non-intrusive and stays outside the water column. This enables a water system operator to quickly inspect a larger portion of their water distribution network and obtain actionable information to optimize pipe cleaning and line efforts.
