US Infrastructure Situation Aging Infrastructure Infrastructure design life is 50 to 80 yrs Out of sight = out of mind EPA: $170 to 493 Billion in next 20 years* Congressional Budget Office: $245 to $424 Billion* Water Infrastructure Network: $420 Billion* Limited funds = need to prioritize Military bases arguably worse “Ostrich” Consideration* EPA 816-R-05-001 Drinking Water Infrastructure Needs Survey & Assessment – 3rd Report to Congress, June 2005

Current Situation* 2009 – WSSC had 1,847 water breaks
• 611 breaks in January 2009
240,000 water main breaks/year in USA
Large utility breaks in the Midwest increased from 250/yr to 2,200/yr over 19 years
Baltimore, MD had 1,190 main breaks in 2003 • more than 3 per day
British study in 2005 correlated diarrhea with low water pressure events (including main breaks)
USGS estimates 1.7 trillion gallons of water lost in the US per year, at a cost of $2.6 Billion

What Has Been Done?
Engineering firms develop one-off, proprietary solutions (excel, access, GIS, etc.)
Difficult for clients to use / limited training
No upgrade path
No $$ vehicle for updates

Risk-Based Planning Represents a New Focus for Most Utilities
Historical Approach to Renewal Planning
•Budget Based on Last Year•Little knowledge of system risks
Backward Looking
•Projects determined as problems arise during the year
Reactive
•Do as many projects as you can afford each year
Budget Constrained
•Money is spent but overall risk may not have been reduced much
Ignores asset and
system risks
Risk-Based Renewal Planning
•Based on asset risk scores throughout system and long term forecasts of risk and cost
Forward Looking
•High risk assets slotted for renewal before failure occurs
Proactive
•Budget could be determined based on agreed risk targets for system
Risk or Budget
Constrained
•High risk assets addressed first•Budget may rise or fall to meet risk targets
Focused on risk
management
