September 24, 2020 – Envirologics CEL (Clean, Evaluate and Line) of Drinking Water Pipes in Saint Jerome, Quebec

Pre-Project Condition:
This project contained 2 x 15m long, 150mm (6”) iron pipes. Each pipe contained a 90° bend and are located below a restaurant floor at a local highway rest stop. Pipe access was below grade in a mechanical room at one end and a buried drinking water tank at the other end. The pipes were both highly tuberculated resulting in low water pressure and flow rates to the businesses. A remaining wall thickness evaluation was also conducted to determine the pipe’s remaining structural properties.
