  • Ask question: how many of you know the average condition of your roads? How many know the average condition of your water main? How many tried putting both together to develop a collective capital improvements plan? How much did it cost you?
  • If I did not do anything, eventually the asset will reach a point of major rehabilitation, usually at the end of its asset life, and require major investment in order to increase its condition. However, if proper intervention were to occur at proper time intervals, point of major re-construct would not be reached for a long period of time.
  • Pipes are different – joint failure and environment. Three stages…First challenge: curve itself (environment, material, operation dependent) – nobody observed this – it’s out of sight Second challenge: what is condition? Cannot make judgments on number of breaks only!!! Too many breaks to be realistic… My talk is about the third curve of the theoretical deterioration curve: i.e. we know we have breaks in the pipe…
  • Condition is a function of three parameters: physical, service delivery, liability
  • How can I put all that information together and make sense of it? More importantly, can I use these signs to decide what water main to tackle and when?
  • Not all info on this is absolutely necessary, this method is very customizable, hence very community need driven
  • This shows average pressure variation. Similar graph could be produced for fire protection variation. Also, start grouping
  • Of all your water main, you should tackle the highlighted water main and you should tackle them in the order presented, hence the what and when. Emphasize importance of technology: GIS, CMMS – makes post processing easier, data management easier, also, of course, the importance of data collection…. There is one thing the previous pavement management model cannot do, that is collective infrastructure prioritization.
  • This is the justification portion

    • What’s it like in your community or agency??
    • Elected Officials are easier to work with than ever??
    • Value of all of your community’s infrastructure – and who “gets it”?
  • CHECK-IN
    • Pavement Management plans?
    • Tools?
    • CIP?
    • 1 or more Utility Asset Management plans
    • Tools?
    • Combined Asset Management plan
    • Budget for above?
  • City of Romulus Area : 35.9 mi 2 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
  • Simple Tool
  • Asset Management with Simple Tools and Historic Data?
  • Your Tools?
    • Push pin map, spreadsheets, lists, GIS?
  • 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
  • Asset Condition Model Condition Point of Major Rehabilitation Life of Asset Time Road Assets
  • Challenges for Water Main Asset Condition Model Condition Time Point of Action
    • Environment
    • Material
    • System Operation
  • Two Central Management Questions
    • Condition assessment – what is it an how can it be done?
    • Prioritization – when to intervene or in what order?
  • 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
    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
    • Consequence of failure
    • Impact on future development potential…
  • City of Southfield Area : 26.2 mi 2 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
    • When prioritizing water main improvements,
    • also concurrently prioritize for:
    • Road improvements
    • Sanitary sewer improvements
    • Storm sewer improvements
  • Sanitary Sewer Priority Map Water Main Priority Map Roads Priority Map
  • Street Maintenance and Asset Management
    • DPW utilizes asset management principles to manage and prioritize scheduling and type of repair
    • Roads are rated based on Pavement Quality Index
  • Road Infrastructure Prioritization
