Acoustic-Based Condition Assessment Provides Accurate Remaining Pipe Wall Thickness Measurements for Columbus, Ohio

The City of Columbus, Ohio’s water infrastructure is quickly coming to the end of its life expectancy. As a result, the city is significantly increasing its budget for large-scale pipe replacement projects. Malcolm Pirnie, a Division of Arcadis, the engineering firm that is assisting Columbus with its water infrastructure improvement projects, approached Echologics to perform an acoustic-based assessment of the remaining wall thickness of selected 6–12 inch Ductile Iron and Cast Iron water pipes that run throughout the city.
