An Owner Operator’s Approach for Asset Management – on a Budget

Lane Longley, City of St. Petersburg


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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)
