How Utilities Get Control of Their Distribution Systems

  1. 1. By Katie McCainWachs Water Services February 22, 2011
  2. 2. Agenda Industry Challenges Valve Operability High Risks/Costs of Taking No Action Asset Management Where To Start/Strategies Summary
  3. 3. Industry Challenges Aging infrastructure Reductions in manpower Experience/knowledge loss Deferred maintenance Funding gaps Increasing customer demands Supply availability Infrastructure security
  4. 4. What Is Valve Operability? Definition of Operability Initial Operability: Upon arrival, can the valve be found and easily operated by the crew? Right Here, Right Now…
  5. 5. Valve Operability Status Quo Based on 750,000 assessments
  6. 6. Low Operability =Loss of System Control (Increases Levels of Risk)
  7. 7. Run to Failure - Strategy 100% Reliability Threshold PainOperability Run to Failure Time
  8. 8. Run To Failure (example)Buy a Buy a Buy aCAR CAR CAR Run to Failure Run to FailureReliability Threshold $25,000 $25,000 $25,000
  9. 9. Default “Run to Failure” A.M. Strategy Is easy/requires no action/abdicates responsibility Is great for awhile but eventually causes service disruptions Service disruptions cause customer dissatisfaction Customer dissatisfaction causes reactive responses not planned activities Never get caught up/never get control of the system
  10. 10. High Risks/Costs of Taking NoAction Overtime and repeat visits Unnecessary replacements Property damage/restoration cost Delays in locating valves Loss of water Loss of life Injuries to workers and citizens Lawsuits from injured parties (medical and property) Continued catastrophic events
  11. 11. High Risks/ Costs of Taking NoAction (cont.) Keeps your utility in a reactive mode, chasing emergencies, trying to keep up Low operability = loss of system control Water quality challenges Lack of fire protection Lack of ability to isolate contamination Major break containment issues Business interruption/transportation interruption Interruption of service/customer complaints The current situation is not sustainable
  12. 12. Asset ManagementStart by answering five key questions
  13. 13. Five 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?
  14. 14. What is the required level What is the current state of my assets? of service? Determine Determine Inventory Assess Set Target Residual RRR $ Assets Condition LOS Life & Timing Assign Determine Determine Fund BRE Rating Appropriate Appropriate Build the AMP Your Strategy (Criticality) Maintenance CIPWhich assets What are the best O&M What is the bestare critical to and CIP strategies? funding strategy? sustainperformance ?
  15. 15. Reliability Centered Maintenance (example)Buy a Oil TransCAR Wipers Change Fluid Tune Up Air Pressure Flush Wiper Fluid Struts Battery Reliability Threshold 100% Sustainability Execution Time
  16. 16. Where to Start/Strategies • Total system assessment program approach • Large & Critical Valves core of the system • Representative survey state of the system • Specific areas section of the system
  17. 17. Summary The time for action is now, before there is an emergency Look at your system and identify the most critical assets in it Start by inventorying and rehabilitating those assets A long-term approach to valve maintenance will set the utility up for future generations There are proven solutions Solutions fund themselves Start with valves
