Start by answering five key questionsStart by answering five key questions
Five Key QuestionsFive Key Questions1. What is the current state of my assets?
What do I own? Where is it? What condition is it in? What is its remaining useful life? What is its remaining economic value?
2. What is my required level of service (LOS)? What is the demand for my services by my stakeholders? What do regulators require? What is my actual performance?
3. Which assets are critical to sustained performance? How does it fail? How can it fail? What is the likelihood of failure? What does it cost to repair/refurbish/replace? What are the consequences of failure?
4. What are my best O&M and CIP investment strategies? What alternative management options exist? Which are most cost effective for my organization?
5. What is my best long-term funding strategy?

What is the Status Quo?• Operability
• System Information Gaps• Asset Inventory• Asset Locations• Accuracy of Asset Info
• Continued Status Quo?

• 40% of all water valves are inoperable• 10% of all hydrants are inoperable; including
inadequate flow• 10% of all valves are paved over• 9% of all distribution valves are found in the

• No Idea what was Underground
• No information on Operability

• City of Charlotte, NC• Building GIS From The Ground Up
• Asset Information “captured” can provide information from the field back into planning (including Asset Management / CIP)
Many Approaches 3

CIP PlanningCIP PlanningDollars Spent Wisely
• (12) 20” transmission valves found shut – twin 54” mains deemed unnecessary
• Pump station at capacity – Closed 7 pressure boundary valves found in the wrong position – MGD cut in half
• Rehabilitation of a large externally geared pump station valve – plan to replace required draining an entire reservoir

Where to Start: Strategies
• Total system assessment
program approach
• Large valves core of the system
• Representative survey state of the system
• Specific areas section of the system
