ABES was contracted by SARP-10 to provide the assessment of sewer lines using the Sewer Line Rapid Assessment Tool (SL-RAT). SL-RAT is a highly portable on-site assessment tool for quickly detecting blockage conditions in gravity-fed sewers. SL-RAT efficiency can lead to an operating cost 1/10th to 1/20th that of CCTV. In addition, it allows wastewater utility operators to economically use a Condition-Based Maintenance strategy to improve SSO performance while using fewer resources.

ABES was responsible for preparing and setting up temporary traffic control, field assessments of the pipes using SL-RAT, reviewing collected data, and uploading them to SL-DOG for SARP-10 use.
