Decision-Support Tools for Predicting the Performance of Water Distribution and Wastewater Collection Systems

摘要

Water and wastewater infrastructure systems represent a major capital investment; utilities must ensure they are getting the highest yield possible on their investment, both in terms of dollars and water quality. Accurate information related to equipment, pipe characteristics, location, site conditions, age, hydraulic rates, and water quality is critical to industry and municipalities to enable the most cost-efficient operation, maintenance, and rehabilitation of existing systems. This report summarizes information on European efforts to optimize operation, maintenance, and rehabilitation activities related to water distribution and wastewater collection systems. The report includes a description of: the capabilities and the data required to run eight pipe assessment software applications or models, the infrastructure performance indicators used by three European water authorities, and an approach to collect the necessary performance indicator (PI) data, based on our assessment of the European experience.
