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. SL-RAT now enables wastewater utility operators to economically use a Condition-Based Maintenance strategy to improve SSO performance while using less resources.

The SL-RAT is composed of two components– the Transmitter (TX) and the Receiver (RX). Each SL-RAT device is sold or leased as a pair – with the TX providing the active acoustic transmission through the pipe and RX “listening” for the blockage and processing the blockage assessment result.
