The Sewer Line Rapid Assessment Tool, or SL-RAT™, is a highly portable onsite assessment tool for quickly detecting blockage conditions in gravity-fed sewers. The SL-RAT’s ability to provide a blockage assessment in 3 minutes or less, with no flow contact leads to an operating cost 1/10th to 1/20th that of CCTV. And, more importantly, the SL-RAT now enables wastewater utility operators to economically use a Condition-Based Maintenance strategy to improve sanitary system performance while using less resource.

The SL-RAT is composed of two components – the Transmitter (TX) and the Receiver (RX). Each SLRAT device is sold or leased as a pair – with the TX providing the active acoustic transmission through the pipe. Think of the TX as “yelling” down the pipe, and the RX providing the microphone and signal processing capabilities to listen and interpret the received acoustic signal. Think of the RX as the brain “listening” for the blockage and processing the blockage assessment result.
