Screening Quickly at Low-Cost
In 2011, Georgia’s Environmental Protection Division issued a consent decree that required Augusta to evaluate and point repair for the entire collection system. While the city has worked diligently against the corrective action plan, the SL-RAT has provided a complementary tool that enables rapid screening of the entire collection system. By identifying where blockages are at low cost, more expensive cleaning resources could be deployed in a more impactful way.
“…the SL-RAT is one of those things that’s turning the baby steps more into a full stride. I honestly can’t say enough good things about it.”
– Jody Crabtree, Asset Manager for Augusta Utilities Department
Key Program Results
Augusta reduced their sanitary sewer overflow count by almost 33% in their first year of transitioning from a reactive to a proactive approach. By inspecting all of their lines using a low-cost tool, they were able to determine where to deploy resources quickly, in an meaningful way.
Three Million Feet Inspected in Two Years
After two years of conducting acoustic screenings, the City of Augusta described the value of the SL-RAT in a report for the NASTT No-Dig Conference. They found that a two-person crew screened an average of 7,500 feet of pipes per day. In two years, Augusta’s crews screened over 12,000 segments (3 million feet). By screening first, they recognized that 60-85% of these pipe segments that would have been cleaned under their previous time-based maintenance strategy actually had plenty of flow capacity.
Integrating Acoustic Data with GIS System
Since implementing the SL-RAT, Augusta looked to streamline the information collected with the SL-RAT with their utilities department operations so they could improve response time. They worked with their work order management system, CityWorks, to automate the process. With CityWorks, Augusta’s GIS system updates asset condition in real-time so that field crews can make informed decisions.
“We have quality, valuable information tied to that asset, you can evaluate things much more easier, geographically.”
