1. What is the primary purpose of the PACP program?
A. Pipeline construction
B. Standardizing sewer inspection data
C. Pipe manufacturing
D. Wastewater treatment
Rationale: PACP ensures consistent coding and reporting of pipeline inspection
data across the industry.
2. Which type of inspection method is most commonly used in PACP?
A. Sonar
B. Laser scanning
C. Closed Circuit Television (CCTV)
D. Manual entry
Rationale: CCTV inspection is the core method used for visual pipeline
assessment under PACP.
, 3. What does O&M stand for in PACP terminology?
A. Operations & Monitoring
B. Operations & Maintenance
C. Observation & Management
D. Organization & Maintenance
Rationale: O&M defects relate to maintenance-related issues such as debris or
roots.
4. Which code category represents structural defects?
A. S
B. M
C. O
D. L
Rationale: “S” codes are used for structural defects affecting pipe integrity.
5. What is the purpose of a manhole inspection?
A. Pipe cleaning
B. Assessing access point conditions
C. Flow measurement
D. Pipe installation
Rationale: Manholes provide access and are inspected for structural and
operational conditions.
6. What does the term “clock position” refer to?
A. Inspection time
B. Pipe depth
C. Location of defect around pipe circumference
D. Flow rate
, Rationale: Clock positions (e.g., 12 o’clock) describe where a defect is located in
the pipe.
7. Which defect is considered an operational defect?
A. Crack
B. Fracture
C. Grease buildup
D. Hole
Rationale: Grease buildup affects flow but does not damage pipe structure.
8. What unit is commonly used to measure pipe diameter?
A. Liters
B. Millimeters or inches
C. Seconds
D. Pascals
Rationale: Pipe diameter is measured in length units such as mm or inches.
9. What is a lateral connection?
A. Main pipe
B. Pipe connecting building to main sewer
C. Inspection camera
D. Pump station
Rationale: Laterals connect properties to the main sewer line.
10.What is infiltration?
A. Wastewater leakage out
B. Groundwater entering pipe
