Summary of Pipe Defect Occurrence:
- All Types Of Potential
Pipe Leaks Detected
- One day's field-work
quantitatively shown on one page.
- Defect character
immediately apparent.
- Quantitatively select
pipe sections for rehabilitation
Interpretation:
- 94% of defects are due
to joints
- Relative quantity of
defects readily identified:
- From most to least:
14,13,9,7,11,3,15,8,5,12,4,10,1,6,2
Analysis shows that section
MH14 to MH15, 7% of total length,
is the potential source of 50% of infiltration for the total length of
pipe sections tested.
