Rapid inspection device uses acousticsProblem
A major federal facility in Missouri wanted to develop a picture of flow conditions in its wastewater collection system.
Solution
CH2M HILL’s Lawrence, Kan., office chose the Sewer Line Rapid Assessment Tool from InfoSense to identify blockages and conduct a broad flow condition survey to prioritize cleaning. The transmitter, placed in an open manhole, transmits tones. In a downstream manhole, the receiver compares the tones with sounds it should hear in a clean pipe. If the signal is degraded, algorithms analyze it and present the operator with a simple assessment in real time on a scale of zero
