Wastewater Collection System Condition Assessment Using CMMS

– Inspect and asses the condition of assets

– Target maintenance and capital improvements where greatest needs exist first

– ID and Assess Risk of blockages and failures to prioritize less critical needs

– Store inventory, condition videos and photographs in Asset Management, CMMS, GIS, and modeling database

– Manage performance, level of service and sustainability by considering service level, risk, condition and budgets

Collection System Condition Assessments Guides the Efforts of

Asset Management

– A process that minimizes the total cost of owning and operating a collection system while

– Delivering service levels that protect public health and the environment and

– Ensures reliable and sustainable operation for the long-term.

Asset Management (AM) is:

Why Develop aCondition Assessment Program?

All Assets Deteriorate and Eventually Fail

Structural defects may interrupt service and cause roadway subsidence and failure

Roots and debris cause backups and overflows

Infiltration and Inflow reduce conveyance capacity and increase transportation and treatment costs

Condition Assessment establishes the timing of maintenance and renewal investments.

Wastewater Collection SystemCondition Assessment (CA)

WW Collection System CA Programs Provide…

– Insight into the nature of possible failures

• Root cause

• Pattern – deterioration curve

– Timing of possible failures

– Basis for scheduling maintenance and capital improvements

– Justification for annual O&M and Capital Budgets

What Do We Need to Know?

• The desired level of service?

• What assets do we own?

• Where are they located?

• What is their condition?

• What is their remaining useful life?

• What is the economic value of my assets?

• Maintenance and capital improvement priorities

Evaluate Condition Data and Information

• Catalogue condition data according to various failure modes

– Maintenance

– Infiltration and inflow

– Capacity

– Structural

– Corrosion

– Remaining Useful Life

• Evaluate Risk of Failure for each asset– Risk of Failure = Consequence of Failure x Probability of Failure

• Prioritize O&M, Inspection and Rehabilitation– Prioritization based on risk (consequences of failure and various

failure modes: maintenance, structural, capacity, I/I, corrosion,

and service life

• Identify Annual Program Components and Capital Needs– Level 1 inspection, cleaning, Level 2 and 3 as needed

– Repair, rehabilitation or replacement

Prioritize

Most Important Piece

• Your Employees / Co-workers– Without them, you can’t collect your data

– Upset them, you will get bad data

– Ignore them, you’ll miss their input

– Exclude them, you’ll struggle for buy-in later

Most Important Piece cont’d

• Your Employees / Co-workers– With them…the

possibilities are endless.

• A Condition Assessment Program can be greatly improved by using a solid CMMS.

• Capturing accurate data is critical, no computer system ever fixed a poor field inspection.

• Make the most of your data by preserving your agency's corporate “memory”.

• The biggest cost of a CMMS is data collection, input and upkeep (not software/hardware).
