to the sewer network.You cannot inspect nor repair them all at the same time!
The criteria for the need for inspection could be (but not limited to):
The size of the upstream catchment (number ofproperties or population) that the pipeline services.
Under or near very busy roads or proximity totransport related structures (airports/railways).Pipelines servicing Business/Tourist related areas.
So, what is a strategic pipeline for Asset
Inspection of Strategic PipelinesInspection of Strategic Pipelines
Management purposes?“A strategic pipeline is any pipe that,
should it fail for any reason, has an unacceptable level of risk
(to health, pollution or road safety, for instance), ( , p f y, f ),disruption or cost
associated with its failure”.If the pipe line does not match the above description then
inspect another line that does

information necessary to assess an action level(1 to 5). CCTV (+ Pan & Tilt), Sonar – 1st level.
2ND Level Pipeline Inspections –More information needed on those “greyarea” pipelines with defects after the 1st Levelassessment. SSET/Laser Profiling etc – 2nd Level
33rdrd Level Inspections Level Inspections ––Even greater details required before “drastic”Even greater details required before “drastic”action needs to be taken.action needs to be taken.GPR/Seismic assessment etc GPR/Seismic assessment etc -- 33rdrd levellevelThis presentation deals with the 1st Level
The First Level Steps: What makes a Pipeline Strategic.
- The Upstream Catchment/Population.Level of “Customer Volume/Environment impact” shouldth i f il M t I t t tthe pipe fail. Most Important aspect
Inspect your system, not Top to Bottom but
Bottom to Top.
Starting at the STW or WWTP and working upstream you will always inspect your strategic pipes in
“bi t i t” d“biggest impact” order.
Or – Prioritize Inspection order based upon Larger pipes with high flows.
Do your < 15” last. Unless there is a Public relations issue.

Do not clean first. If you do, forget Asset Management.If the sewers are being inspected for strategic reasons then cleaning
b f i ti i l t f i f l ifi th i libefore an inspection, irrelevant of size, falsifies the pipelines efficiency, removes a vast amount of important information and is a
complete waste of money. Light Cleaning causes problems Downstream.These sewers must be initially inspected as they normally function
(a well proven approach throughout the world).Then selectively clean. You will ALWAYS save Money. Try it!
Larger pipelines especially are also too costly to clean “Blind”They may not even have silt in them.
Asset Management is:“Knowing what you have and knowing how it works”

Let the Inspection results create Cleaning, Laser Profiling, Root Removal and Rehab contracts, for instance, with
known quantities. Again, you will always save money
