What Will? Working Harder Won’t Help
Workingsmarternot harder is the essence of Effective Management / Asset Management
Asset Management Helps You Have the Most Impact in Your System By Spending Your Limited Dollars in the Best Way Possible
What you want to do…. Replace all the assets New tank, new pipe, new pump, new filter
$5 Million Elected Officials/ Decision-Makers Say No
Second Choice: $3 M New Tank, New Filter, New Pump Replace Some of the Assets Elected Officials/ Decision-Makers Still Say No
Now What? Repair and Rehabilitate
Analyze Pipe Replace only select pipes too bad for rehab Marginal & Better Stays in Place; Repair wherever possible Rehab Where Possible
Analyze Filter Look for root cause of problem; check media; Look for rehab options
Analyze Tank Check structural integrity; Look for rehab options: Can you sand blast? Repaint? Recoat interior? Clean sediment
Analyze Pump Replace pump impeller, keep pump
Rehab Option: $1 M Reduced Risk almost as low as new assets for 1/5 the cost Rehab Assets
Nothing more than following a systematic approach for managing the assets (Often called the 5 core components of asset management)

What is the remaining life of my assets? 100 Years 1 Year 10 Years 15 Years 20 Years
Replacement Current Value Historical Value What is the value of my assets?
What is the energy use of my assets? Electricity 50 KW 10 Hp 150 Hours Run Time Solar Powered

Components of Criticality What is the probability or likelihood that a given asset will fail? How do my assets fail? What’s the condition of my assets? What is the consequence if the asset does fail? What is the cost of the repair? Are there legal consequences, environmental consequences, social consequences? Are there redundant assets?
MEDIUM RISK MEDIUM RISK Critical Assets – Risk Analysis Consequence of Failure Which category of assets do I care the most about? The least? Probability of Failure

Life Cycle Costing: Operation and Maintenance • Maintenance activities extend the life of assets • Lots of maintenance that can be done, but • Maintenance takes Time and Resources • So…. How do you decide what to do? Concept of Risk • High Risk Assets: Do what you can to prevent failure and reduce risk of asset • Low Risk Assets: Do only what’s absolutely necessary
Not possible to know the optimal time to replace every asset So… need to use the concept of risk In Theory, There is an exact right to replace an asset X X Condition X Optimal Replacement Point X X Time Life Cycle Costing: Replacement of Assets X = Repair
High risk : replace assets early, before failure Low risk assets: run to failure and replace afterwards X X X X Replacement Point Replacement Point Condition Condition X X X X X X Time Time Life Cycle Costing & Risk
