http://www.ohm-advisors.com. Government organizations have to balance declining revenues with rising maintenance costs. It's no secret that America's infrastructure is deteriorating at an alarming rate. Here is a simple concept for using asset management principles on water main systems. What you'll learn: Develop an understanding for cheap and cost effective asset management using readily available data. Review a method for needs prioritization. Identify additional steps for prioritizing multiple assets.

    Asset Management for Infrastructure: Identification, Prioritization and Justification Asset Management for Infrastructure: Identification, Prioritization and Justification Presentation Transcript

    • Water Main Asset Management Identification, Prioritization, Justification Evan N. Pratt, PE Principal 254 W. Eastland Street | Gallatin, Tennessee 37066 | www.ohm-advisors.com
    • Learning Objectives • Develop an understanding for cheap and cost effective asset management using readily available data • Review a method for needs prioritization • Identify additional steps for prioritizing multiple assets
    • Check In What’s it like in your community or agency?
    • Check In Value of all of your infrastructure? Lowest cost of reinvestment? Who “gets it”?
    • Check In Tools CIP 1 or more Utility Asset Management plans Combined Asset Management plan Budget for above
    • Area: City of Romulus 35.9 mi2 Population: 2000 census: 22,979 2007 estimate: 24,414 Infrastructure: water main: 300 miles san. sewer: 150 miles roads: 220 miles Approximate Replacement Value: $1 Billion
    • What is Asset Management?
    • Providing the desired level of service at the lowest LIFE CYCLE cost.
    • What is Asset Management? ?
    • Asset Management with Simple Tools and Historic Data
    • Your Tools Main break sheets Push pin map Spreadsheets Lists GIS
    • Simple Tool
    • Asset Condition Model Road Assets Condition Point of Major Rehabilitation Life of Asset Time
    • Challenges for Water Main Asset Condition Model • Environment Condition • Material Point of Action • System Operation Time
    • Two Central Questions Condition assessment • What is it • How can it be done? Prioritization • Critical Asset concept • When to act, in what order?
    • Condition Assessment 1. Physical Signs 2. Service Delivery Signs 3. Signs of Increasing Risk
    • Condition Assessment Physical Signs • Number of water main breaks increasing • Increasing age of water main Service Delivery Signs • Discoloration in the water • Inadequate water pressures • Inadequate fire hydrant flows
    • Condition Assessment Signs of Increasing Risk • Critical pipe failures • Non-compliance with Safe Drinking Water Act • Severe breaks when they occur • Angry Planners or Elected officials…
    • The W.I.N. Model Service Delivery • Pressure variations • Fire protection capacity or ISO hydrant test results • Pipe friction losses per length of pipe
    • The W.I.N. Model Physical Conditions • Age of pipe assets • Number of water main breaks • Frequency of breaks • Corrosion
    • The W.I.N. Model Risk Management • Severity of breaks • Consequences of failure • Future development potential
    • City of Southfield Area: 26.2 mi2 Population: 2000 census: 78,296 2007 estimate: 76,285 Infrastructure: water main: 360 miles san. sewer: 300 miles roads: 242 miles Approximate Replacement Value: $1.5 Billion

    • Collective Prioritization How to Eat the Elephant: • Water Main improvements • Sanitary sewer improvements • Pump Station improvements • Plant Improvements
    • Collective Prioritization If Possible • Storm sewer improvements • Road improvements

    • Education Program: KISS
    • Learning Objectives • Developing an understanding for cheap and cost effective asset management using readily available data • Evaluating a method for needs prioritization • Identifying additional steps for prioritizing multiple assets
    • Key Points • People need to know the total value of your system • Use the car analogy; millions are a modest % • Assess the condition of your assets • Prioritize replacement and maintenance
    • Key Points • Engage decision makers in the categories for prioritization • Critical assets, development, fire protection all get people’s attention! Tie to reinvestment needs.
