Reducing the Consequences of Failure
America’s Infrastructure is Failing
• One Million Miles of Water Mains are in place – U.S.
• Some pipes date back to the Civil War era
• 240K Main Breaks per Year• ~700/day• Break Clock
Reducing the Consequences of Failure
America’s Infrastructure is Failing
• Average – 1 Break / 4 miles• Currently Replacing Pipe -½
% per Year (200 yr plan)• The need will double from
roughly $13 billion a year today to almost $30 billion (in 2010 dollars) annually by the 2040s
• 7 Billion Gallons Lost Each Day (ASCE)
Reducing the Consequences of Failure
Facts and Figures• Approximately 175,000 Gallons Per Minute Flowing• More than 4 feet deep in some residential areas.
Areas submerged in up to 4 feet of
water .
Hundreds of emergency services employees deployed.
6,000 homes impacted Flooding / No Water

Reducing the Consequences of Failure
Information Usability: Content
• What assets are represented in the information system?– All pipes, valves, meters, etc?
• What type of information is documented for assets in the system(s)?– What’s the condition?
– What are the as-is operating characteristics?
• Are the assets organized in a logical network that can be called upon to perform analyses?

Reducing the Consequences of Failure
Water RF (study 4369 – UIM Article 4/15/14)
“…having an asset management program in place can play a key role in minimizing damage due to infrastructure failure, particularly if the program had a special focus on the valve management program. Knowing the exact location of each valve, whether the position of the valve was open or closed and having performed regular operability maintenance of the valves, made it more likely that the utility’s crew could quickly isolate the area of the break, and thereby, minimize the amount of water discharged and damage to surrounding properties.”
