Abstract
Economical Sewer Main Rehabilitation Utilizing ArcGIS and Dynamic Segmentation
Track: Water Distribution, Wastewater, and Stormwater
Author(s): Dale Clancy, Jan-Mark Gustafson, Lynne Higgins
Traditionally, sewer main condition is determined by video camera inspection and evaluation. The high cost of sewer camera inspection has led to a selection process that considers maintenance and sewer cleaning records in conjunction with sewer main characteristics to determine inspection priorities. ArcGIS provides a spatial platform to consider deterioration, quantify failed mains and quickly identify sewer camera inspection priorities. To maximize limited rehabilitation funds, the industry's focus has shifted to partial and spot rehabilitation strategies. Dynamic Segmentation and a treatment-versus-condition approach is used in evaluate partial rehabilitation alternatives that improve on the economics of rehabilitation decisions.
