This presentation discusses the forensics program initiated by WSSC to collect, evaluate and analyze pipe failure data to establish correlations and identify trends to minimize future failures through improved design standards, construction practices and replacement and rehabilitation planning. The program focuses on cast and ductile iron pipes which make up 85% of the WSSC water distribution system. Key components of the program include laboratory and field testing of samples, development of GIS database, failure analysis, and evaluation to support condition assessment efforts and asset management initiatives as part of the WSSC Asset Management Program and water main replacement and rehabilitation planning. Some parameters considered in the evaluation include soil conditions, groundwater table, material composition and age of pipe. Presentation will go through the process used for evaluation and walk though some of the preliminary results.
