NASSCO PACP/MACP/LACP Certified Trainer
What is NASSCO?
National Association of Sewer Service Companies
Formed in 1976
Member Based Organization
Provider of Services and Products to the Owners of Sewer Collection Systems
Founding Mission to Improve Success in Pipeline Rehabilitation Industry Through
– Education
– Technical resources
– Industry advocacy
NASSCO WEBSITE
PACP
Pipeline Assessment & Certification Program
Implemented in 2002
Program Purpose:
– Standardization and Consistency in sewer pipe condition evaluation
– Management of collected CCTV data.
Based upon Water Research Centre (WRc) codes (Swindon,
England)
Defect Coding System to document pipeline condition
Re-certification required every 3 years
PACP Coding Example
PACP Coding Example
MACP
Manhole Assessment & Certification Program
Developed In response to industry demand for a program
to code manhole defects
Version 6.0.1 (November 2010 Release): Two inspection protocols
– Level 1 inspection - basic condition assessment to evaluate general
condition
– Level 2 inspection - detailed information to document all defects & condition
MACP Coding
– Applies PACP defect coding system
– Incorporates ASCE manhole Standards.
PACP certification is prerequisite for MACP training & certification
MACP certification is valid for 3 years
MANHOLE DIAGRAM
MACP Coding Example
LACP
Lateral Assessment & Certification Program (LACP)
Training addresses fittings and access points unique to laterals
Coding applies PACP defect coding system
PACP certification is prerequisite for LACP training and certification
LACP certification is valid for 3 years
LACP Coding Example
Why NASSCO Train?
People have different:
– Perspectives
– Opinions
– Levels of Experience
– “Learned Eye”
Utility owners need measures to gauge:
– When to act
– When to wait
– When and how to prioritize
Why NASSCO Train?
To Compare One Pipe, Manhole, Lateral
evaluation to another and To Prioritize
System Needs, Requires:
Standardization
Consistency
Objectivity
Managed Data
Training Operations Staff
Operators have
– Hands on field experience
– Technical training
– Inspection knowledge and experience
– Field “learned eye”
Operators do not have
– Data analysis experience
– Design experience
Training Operations Staff
Operators are the eyes and ears of the
“office” reviewers
Operators are not technical/engineers… and
proud of it
Training Operations Staff
When you are coding, think about:
– Recording what you see thoroughly and consistently
– Code all defects regardless of repetitive/continuous defects in
segment.
– Don’t allow coding to become “relative” to severity of defects in pipe
– Don’t exaggerate or over emphasize a defect
– Don’t minimize or skip a small defect.
Training Operations Staff
When Performing CCTV:
– Field conditions make achieving clear & accurate video a difficult task
– Important to obtain the best recorded image feasible
• Camera Speed, orientation, and lighting are essential
• NASSCO has clear & detailed guidelines to assist in
achieving high quality video inspections & assessments
Training Operations Staff
Operators hands on experience and learned eye applied in coding can result in:
– Coding based upon real time view vs. recorded
view • Ex: Depth of a crack in the manhole wall
– Codes that reflect surrounding conditions • Ex: Crack with evidence of I&I
– Defect identification that may be missed or unclear
in recorded version • Ex: Hearing water travel down a manhole wall
Defect Coding Examples
Training Operations Staff
Tips to Operators on NASSCO Training
1. Bring field experience with you; good opportunity to ask
questions of trainer & industry peers
2. Table your pre-conceived notions; you might actually
learn something you didn’t already know
3. Adopt PACP standards and use the training materials to
enhance your knowledge and experience; always room
for improvement
4. Appreciate that your job in field is critical to success of
system assessment; office staff are blind, deaf and dumb
without it!
Training Technical/Engineering Staff
Engineers have
– Data analysis experience
– Design experience
– Construction method knowledge
– Construction material knowledge
Engineers do not have
– Hands on field experience
– Technical field training
– Field Inspection knowledge and experience
– Field “learned eye”
Training Technical/Engineering Staff
Technical knowledge applied in coding review can result in:
– Coding based upon material degradation
knowledge vs. code applied • Ex: RCP pipe with rebar exposed
– Evaluating composite codes vs. one defect code • Ex: Pipe and manhole defects found
– Defect identification that may be missed or unclear
in field review • Ex: Lateral defect missed in CCTV coding of pipe
Field Coding vs. Technical Review Example
Missing Something??
Training Technical/Engineering Staff
Tips to Technical/Engineers Staff on NASSCO Training
1. Bring your technical knowledge and experience with you; good
opportunity to ask questions of the trainer as well as industry peers
2. Table your pre-conceived notions; you might actually learn
something you didn’t know
3. What you learned in training/college can be different when applied
in the “real world”
4. Adopt the training materials to your knowledge and experience;
always room for improvement
5. Appreciate that you are reviewing work performed in field conditions
under varying conditions of weather and system operations; not
easy and many times a dirty job
Conclusions
NASSCO Training is Beneficial to Operators, Technical Staff and Engineers Alike
NASSCO Coding Does Not Replicate/Replace Knowledge and Experience
Combining Knowledge/Experience with NASSCO Principles is Key!
