1 Affordable Asset Management Making Use of the Data You Have: An Owner s Perspective An Owner Operator s Approach for Asset Management on a Budget Lane Longley, City of St. Petersburg Presented by the April

2 Asset Management: Asset management is a systematic process of operating, maintaining, upgrading, and disposing of assets cost-effectively. The Goal, is to monitor and maintain your wastewater collection system, with the objective of providing the best possible service to users. Two Major Considerations: Asset Management Systems can be expensive to acquire and implement. How much of an Asset Management System do I really need for my wastewater collection system? 2

3 Asset Management is Needed Using one system for all work and asset management can help deliver three operational benefits: more productive workers more reliable assets technology cost savings What utilities often have is a collection of strategic assets, each with its own silo of data: As-Builts SCADA CCTV Inspection Reports & Video Work Order System Production Reports 3

4 Asset Management and Enforcement Agencies: FDEP & USEPA Enforcement Agencies Recognize the benefit and need of Asset Management, but they also understand that Asset Management is Scalable so it can be implemented by organizations for systems of any size. CMOM - Utilities still need to prepare for it, the reporting and administrative programs will require wastewater utilities to convey information on capacity, proper management, operation and maintenance. 4

5 Asset Management Systems can be Expensive to Acquire and Implement The Money Cycle What is Your Bottom Line? (Best bang for the buck) What Can I do with What I Already Have? 5

6 What is the Money Cycle and How does it affect my Program? What can I do about it? How can I prepare for it? Causes for the cycle: > Politics > Public Perception > Economic Environment > Enforcement Agencies 6

7 What s Your Bottom Line = Best Bang for the Buck Mainframe systems are very expensive but can link maintenance costs, condition ratings, criticality ratings, and other attributes to assets They interact directly with GIS and can more easily produce graphic depictions for analysis and planning They can produce Work Orders based on a set schedule for routine preventive maintenance Uploading existing Data can be Problematic 7

8 What s Your Bottom Line = Best Bang for the Buck (cont d) Cloud and Web Based Asset Management Systems for Utilities are currently increasing in development. This brings up the obsolescent consideration. If I buy now how long before my system is out of date? Should I compromise? Can I accomplish my mission another way? How badly do I need the advantages? Do I have any choice?...really? 8

9 What s Your Bottom Line = Best Bang for the Buck (cont d) What can you do with Existing Systems? Maps Printed Maps (the Bible) Electronic Maps (GIS) As-Builts Files Manhole Inspections CCTV Logs Dispatch Card File Spreadsheets Identify Key Fields Assign Condition and Criticality Ratings Sort Other Software Partially Implemented Asset Management Systems Out of Date Systems Pump Station Files Pump Maintenance Histories (PM s) Force Main Designs & Locations Valve Locations & Maintenance Histories 9

10 Once I get Organized Where Do I Begin? List Your Current Challenges: Sanitary Sewer overflows Capacity issues Inflow and Infiltration (I&I) Root intrusion Cross connections to drainage Hot Spots What Information is currently available? Fill in the gaps Take an Assessment/Inventory: How can I figure out what condition my system is in now? 10

11 Challenges Facing Wastewater System Owner- Operators Sanitary Sewer Overflows Capacity Issues Inflow and Infiltration (I&I) Root intrusion Cross Connections to Drainage Hot Spots Private Property Issues Pumping Stations Private collection Systems Grease Management Private Laterals Inadequate System Information Historical Information GIS Applications Lacking 11

12 Assessment: Take Inventory Get an Idea of what You Have and What Condition It Is In: Inventory of the System Manholes Gravity Pipes Pumping Stations Force Mains Valves 12

13 Inventory How do I Track my Inventory Information? Data Base Systems = Big $...or not so much Installed Web Based Spreadsheet Based (Re-)Organize your Data Basin Oriented Approach Upstream MH GIS CCTV & Video Storage Inspection Reports Condition Ratings Prioritizing the Work 13

14 What Should my Maintenance Program Look Like? Preventive Posture, not Reactive! Maintenance Cycle - How often is Enough? In-house or Out-house - What to do? Line Cleaning Root Control Force Main Pigging Pump Replacements/Rebuilds MH & Line Replacements & Rehabilitation 14

15 Moving to Preventive Maintenance Quick Television of Gravity Lines (QTV) Manhole Inspections Decide on Your Format MACP or Your Own System Consistency is Paramount Smoke Testing Identify Storm-Water Cross Connections, Inflow Points, Broken Clean-outs, Private Problems 15

16 Maintenance Cycle How Often is Enough? Every 5-6 Years for: QTV Inspections Cleaning Root Control CCTV Inspection Manhole Inspections Annual Maintenance for: PS Pumps Every 2 Years: Force Main Pigging More frequent: Valve operation & ARV cleaning Equipment Maintenance 16

17 In-house or Out-house - What to do? Contractors can be very useful: Provide Specialized Equipment and Personnel for Special Jobs Types of Work: Whole Operation Specific Projects Repairs & Replacements Pipe Bursting Micro-Tunneling Horizontal Directional Drilling Pipe Lining CIPP Lining Slip-Lining Other Lining techniques Manhole Rehabilitation Coatings Liner Installations Ring & Cover or Chimney Treatments Root Control Grease Management Force Main Pigging Flow Monitoring Smoke Testing Odor Control Wet Well Cleaning & Maintenance Condition Assessment 17

18 Apply the Information to the Prioritized Problems Before Schedule Activities According to Need: Large Pipes First Large Roadways Hospitals Force Mains Continue Rapid Acquisition of Asset Condition Establish and Maintain your Cycle. Approach Budgeting from the Asset Management Perspective After 18

19 Considerations for New Data Systems Size and Affordability Number of Users Compatibility of Existing Data Link to GIS Link to CCTV Inspections Link to SCADA 19

20 Once You Are There Use Asset Management as a Tool Preventive Maintenance Track and Report Performance Measures Dry Weather & Wet Weather SSO s per 100 Miles of Pipe per Year (target 6 or less) Cave-in s & Failures per 100 Miles of Pipe per Year (target 6 or less) 20
