Project Overview
KenWave was engaged by Kenedy Jenks and East Cherry Creek Valley Water & Sanitation District (ECCV) to utilize its Dynamic Response Imaging™ (DRI) technology for condition assessment and leak detection of the Northern Supply Transmission Pipeline. The scope of work was over 3.27 miles (5.26 km) of 48 inch steel.
Throughout the inspection, KenWave’s DRI technology demonstrated its value, correctly identifying pipe wall properties at a resolution of 15 feet. KenWave’s technology identified areas in the pipeline that were undergoing higher levels of degradation and change in wall thickness.
Results
- A residual wall thickness profile of the 3.27 mile scope was delivered with a resolution of 15 feet.
- The residual wall thickness of the watermain shows varying degradation in different locations of the pipeline, these areas were indicated to ECCV.
- Leak detection was performed simultaneously with the condition assessment on the steel watermain.
