  1. Jonathan Mongie Underground Asset Management

  2. Asset Management • Improved Asset Condition • Increased System Efficiency • Prolonged Asset Life • Reduced Operating Costs and Optimized Capital Expenditures • Reduced Overall Life-Cycle Costs • Reduced Risk of Environmental Non-Compliance • Improved Customer Services

  3. Asset Management Stages

  4. Typical Methods of Data Management: • All Paper Survey Results and Work Orders Filed Away in a Cabinet or Binder. • Video in difficult to use formats • Most Data in the Heads of “Long-Term” Personnel

  5. Consequences of Old Methods • Associating Survey Information with the Asset is Labor Intensive, thus Costly. • No Effective Tools for Sorting and Querying Historical Data. • High Risk of Actually Losing Important System Data at Any Moment:

  7. Purpose Built Network Database

  8. From GIS or manhole inspections Inventory of Assets

  9. Data Validation • Assess System Connectivity Situation

  10. Criticality Assessment – Impact of Failure • “Impact of Failure” Query. • Personalized for the Individual Collection System (Highway Names, MH Depths, etc.). • Assigns Scores Depending on Proximity to Geospatial Areas of Interest (Water, Rail, Public Services, Bridges, Schools, etc.). • Then Sums Up the Scores and Sorts Critical Pipes and Manholes to Prioritize for Condition Assessment Surveys.

  11. Criticality Assessment – Impact of Failure

  12. CMMS/Work Planning

  13. Scheduling and Dispatch

  14. Field Mobile Application

  15. O&M Services for Sanitary and Storm • CCTV data is collected using NASSCO standard PACP protocol • Manhole inspections completed using NASSCO standard MACP protocol • Sewer Cleaning • Customer complaint response • SSO data collection • Repair and Replacement Services

  16. Condition Assessment

  17. Condition Assessment Pipe View

  18. SSES Services • Smoke Testing • Dye Testing • Dye Flooding • Flow Isolation • Property Inspections • Vacuum/Pressure Testing

  19. SSES Services – Smoke Testing

  20. Smoke Defect Observation

  21. Smoke Defect Observation

  22. Criticality

  23. Prioritization for Capital Planning

  24. Results – Eliminated 10% of Total Flow

  25. Combined Sewer Overflow Reduction
