This software tool helps users identify pipelines at risk of structural and operational failure. Called SCRAPS (Sewer Cataloging, Retrieval, and Prioritization System), the tool lets small- to medium-sized wastewater utilities estimate the probability and consequence of pipe failure. SCRAPS is based on a Bayesian Belief Network using conditional probabilities to estimate the risk of failure due to structural or operational mechanisms. It incorporates regional priorities and varied experiences in the development of its knowledge base. Published by WERF. 123 pages. Online PDF, plus tool.
