Affordable Asset Management – Making Use of the Data You Have:
An Owner’s Perspective

Presented by the
April 2014
An Owner Operator’s Approach for Asset Management – on a Budget
Lane Longley, City of St. Petersburg
FWEA Collection Systems Committee
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
FWEA Collection Systems Committee
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

FWEA Collection Systems Committee
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.

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
FWEA Collection Systems Committee
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

FWEA Collection Systems Committee
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
FWEA Collection Systems Committee
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?

FWEA Collection Systems Committee
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

FWEA Collection Systems Committee
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?

FWEA Collection Systems Committee
Challenges Facing Wastewater System Owner- Operators
11
• 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
FWEA Collection Systems Committee
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
FWEA Collection Systems Committee
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
FWEA Collection Systems Committee
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
FWEA Collection Systems Committee
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
FWEA Collection Systems Committee
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
FWEA Collection Systems Committee
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
17
• 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
FWEA Collection Systems Committee
Apply the Information to the Prioritized Problems
• 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
18
Before
After
FWEA Collection Systems Committee
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
FWEA Collection Systems Committee
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)
