For 14 years, Severn Trent Water has been committed to network analysis to improve understanding of the operation of its assets, which include 23,000 mi of distribution main. The traditional benefits of hydraulic analysis have been achieved over the years, including investment planning, system design, emergency planning, source optimization, and operational strategy development. Recently, the utility implemented a more widespread use of this technology to realize significant additional benefits, including reduced source output, demand management, and pressure control; improved customer service for pressure and quality; reduced service interruptions through improved local planning; and reduced response time for information at local centers. This article reviews organizational changes, software and hardware changes, and ingredients necessary to "make it work." It also summarizes achievements of the last three years. Includes 8 references, table, figures.
