Digital technology helps South Carolina township improve inspection efficiency

A water and sewer technician from the Taylors Fire and Sewer District in Taylors, South Carolina, reviews CCTV sewer inspection coverage on an office PC.

Taylors Fire and Sewer District in Taylors, South Carolina, must adhere to a 2006 agreement with Renewable Water Resources that requires elimination of inflow and infiltration into their wastewater collection system by 2021. This municipal subdistrict serves 10,000 parcels in central Greenville County, responsible for 130 miles of gravity line and 3,602 manholes.

Aside from nine inline flow monitors and some spotty legacy analog inspection records, Taylors had no empirical system data. They’d need to inspect their entire system, identify problem areas, then plan, schedule and budget for rehabilitation. Monitoring flowmeters, they estimated how long initial CCTV inspections would take, and began immediately.

District officials realized one way to manage costs would be switching to all-digital inspection systems, allowing them to realize economies of scale when all units could connect and share data, decrease significant man hours required by clunky analog systems and eliminate errors introduced into analog data through a less-than-accurate analysis and reporting process.

In 2008, they replaced an old inspection rig with a Ford F450, outfitted with a CUES K2 Base Station and TV reels. Inspection software now includes Pipelogix with Lateral Module, and the CityWorks/ArcGIS CMMS integrated digital utilities management package, used to locate assets, manage workflow, prioritize repairs and issue work orders. The district ports Pipelogix information directly to CityWorks, so upper management to review work orders and work-to-date information.

The efficiency has allowed the district to exceed their goal of inspecting at least eight miles of line annually, with the project on track to complete by 2020. 866/299-3150;
