In April of 2017, a segment of Little Osage Creek interceptor collapsed creating concerns about the overall integrity of the sewer. A multi-sensor (MSI) inspection of the 30- to 36-inch CCFRPM interceptor found a high percentage of the line had excessive deflection (over 16,000 LF showed a 7.5% or greater ovality) with several locations exhibiting severe cracks that were allowing significant inflow into the pipeline. RJN engineers reviewed the MSI footage and developed a prioritized repair and replacement plan, starting with the more severely deflected sections.
