The Sewer Line Rapid Assessment Tool (SL-RAT) from InfoSense uses active acoustics to provide a quick view of blockage conditions within gravity-fed sewers. The test takes three minutes with no flow contact. It allows a crew of two to inspect 10,000 to 20,000 feet per day. It is EPA validated and GPS enabled. Data can be downloaded to the Sewer Line Data Or-Ganizer, or SL-DOG, cloud application for visualization in Google Earth, or integrated with enterprise/GIS applications. 704/644-1164; www.infosense.com.
