Outline of Presentation • What is Asset Management? • Structured Program • Customer Service Expectations • Planned Maintenance • Setting Aside Reserves • Minimizing Whole Life Costs
Asset Management Simplified Initial Purchase Selected Performance Expectation Dependability 150,000 Mile Repairs 100,000 Mile Repairs Planned Maintenance Costs Expenditures Sale or Trade In Automobile Lifespan Source: Adapted from www.efcnetwork.org
Each Part of the Organization Sees Part of the Elephant • O&M sees: Trucks, crews, pumps, etc. • Engineering sees: Studies, capital costs • Finance sees: Interest, other financial costs • IT sees: Cost of IT systems (SCADA, GIS, Network, Computers) • Few see: Internal and external overhead
Each Part of the Organization Needs to Participate in the AM Program
Getting Started in a Structured Way • Two Components • Where are we now, and • Where do we want to be? • “Gap Analysis” • AM Plan Supports Closing the Gaps
Gap Analysis Where are we now ? Source of Water Supply = 110 % of Peak Demand Where do we want to be ? Source of Water Supply = 150 % of Peak Demand
Gap Analysis How to we increase Supply to 150 % of Peak Day Demand ?
Planned Maintenance Initial Purchase Selected Performance Expectation Dependability 150,000 Mile Repairs 100,000 Mile Repairs Planned Maintenance Costs Expenditures Sale or Trade In Automobile Lifespan Source: Adapted from www.efcnetwork.org
Planned Maintenance • What Is Likely To Fail Eventually Without Maintenance? • How Often Should That Asset Be Maintained to Prevent Failure?
Examples: Why do we… • Replace pipes? Reduce risk of water main breaks and outages • Monitor pumping Reduce risk of water stations? outages • Have redundant pumps? Reduce risk of asset failure and water outages • Do preventive Same maintenance? • Increase system capacity? Reduce risk of capacity- related delivery constraints
Likelihood of Failure… …or Consequences of Failure Focus Your Efforts Here H M L Likelihood of Failure L M H Consequences ($)
Risk Cost: A Rational Approach • Risk cost is an inherent cost of asset ownership • It is the product of the likelihood of an event and the dollar consequence of that event • Once we know the risk cost, we can make rational decisions on reducing risk
Example: Risk Cost of Having Your Car Towed • Average towing bill: $240 • Average frequency of needing a tow for your make/model of car: 8 years • Annualized risk cost: $240 x 1/8 = $30 • Add overhead and profit: $10 • Insurance company assumes your risk cost of towing: $40 per year
Consequences of Failure Include Both Direct and Indirect Costs • Direct repair costs • Loss of production/revenue • Social costs (traffic, cleanup, health, etc.) • Image repair costs • Legal costs • Fines, penalties
Setting Aside Reserves • Bond Reserve Fund Typically = 25% of Annual Bond Payment • How Much Can Your Organization Afford to Set Aside For Repair and Replacement? • Option = Annual Depreciation Amount
Depreciation $ X = Original Cost of Asset Y = Life Expectancy, Years $X/Y = Annual Depreciation
Example: Pump Station $ 500,000 = Original Cost of Asset 40 = Life Expectancy, Years Depreciation = $500,000/40 = $12,500/year
Asset Life Cycle Cost Example: Deep Well Pump Station • Consider Capital Costs • Consider Annual Operating Costs • Consider Annual Maintenance Costs • Consider Annual Repair & Replacement Costs • Add Costs and Prepare NPV Cost
Asset Life Cycle Cost Example: Deep Well Pump Station • Capital Costs…………………………………..$213,743/yr • Annual Operating Costs………………….$80,000/yr • Annual Maintenance Costs……………..$25,000/yr • Annual Repair & Replacement………...$25,000/yr • Net Present Worth Cost………………..$5,563,331
What Service Levels Provide Lowest Overall Costs? Total Cost Cost Unplanned R&R Planned R&R High Level of Service Low
AM Benefits Add Up. . . USEPA estimates that good AM will result in at least a 20 percent reduction in asset ownership costs
SummaryAsset Management is: • Structured Program • Customer Service Expectations • Planned Maintenance • Setting Aside Reserves • Minimizing Whole Life Costs
