1. What is the primary purpose of the LACP program?
A. Repair sewer lines
B. Inspect treatment plants
C. Standardize lateral pipe inspection and coding
D. Install sewer systems
Rationale: LACP ensures consistent and accurate assessment and coding of
lateral sewer conditions.
2. What type of pipes does LACP focus on?
A. Storm drains
B. Mainline sewers
C. Water supply lines
D. Private and public lateral connections
Rationale: LACP is specifically designed for lateral pipelines connecting
buildings to mainlines.
3. Which technology is primarily used in LACP inspections?
A. Laser scanning
B. CCTV cameras
C. Ultrasound
, D. Radar
Rationale: Closed Circuit Television (CCTV) is the standard method for
inspecting sewer laterals.
4. What does a continuous defect indicate?
A. A one-time occurrence
B. A temporary blockage
C. A defect extending over a length of pipe
D. A minor issue
Rationale: Continuous defects affect a measurable length rather than a
single point.
5. What is a point defect?
A. A long crack
B. Pipe collapse
C. A localized issue at a specific location
D. Flow restriction
Rationale: Point defects occur at a single identifiable position.
6. What is the purpose of coding defects?
A. For billing
B. For construction
C. For standardized reporting and analysis
D. For equipment selection
Rationale: Coding allows consistent documentation and comparison of
pipe conditions.
7. Which code would represent a crack?
A. OB
B. CR
C. IN
D. DE
Rationale: CR is the standard code for cracks in LACP.
, 8. What does OB represent?
A. Crack
B. Joint separation
C. Obstruction
D. Deformation
Rationale: OB indicates blockage or obstruction in the pipe.
9. What is deformation?
A. Pipe blockage
B. Change in pipe shape
C. Joint leak
D. Root intrusion
Rationale: Deformation refers to distortion from the original shape.
10.What is root intrusion coded as?
A. OB
B. CR
C. RI
D. JO
Rationale: RI is used to identify roots entering the pipe.
11.What is a lateral launch?
A. Pipe repair method
B. Cleaning process
C. Insertion of camera into lateral from mainline
D. Pipe installation
Rationale: Lateral launches allow inspection without direct access.
12.What is the function of a push camera?
A. Repair pipe
B. Clean pipe
C. Inspect short lateral sections
