Impact/Purpose:
This report documents the findings of a project conducted by the EPA and the Metropolitan Sewer District of Greater Cincinnati to demonstrate an innovative, acoustical, sewer inspection technology, the SL-RAT.
Description:
The overall objective of this EPA-funded study was to demonstrate innovative sewer line assessment technologies that are designed for rapid deployment using portable equipment. This study focused on demonstration of technologies that are suitable for smaller diameter pipes (less than 12-inch diameter). One recently developed and commercially-available acoustic-based sewer pipe assessment technology is the Sewer Line – Rapid Assessment Tool (SL-RAT™) manufactured by InfoSense, Inc. (InfoSense) of North Carolina. This report summarizes the collaborative demonstration and evaluation of the SL-RAT. The results of this demonstration of the SL-RAT show promise for the application of this technology as a tool for cost-effective, pre-cleaning assessment and post-cleaning quality assurance. The application of this technology in an overall collection system O&M program should enable wastewater utilities to optimize their sewer cleaning efforts and free up valuable resources to more effectively implement critical CMOM and asset management programs.
