ATTRIBUTION:

Functional Statement:

F81

To minimize the risk of malfunction, interference, damage, tampering, lack of use or misuse.

Objective:

OP5

 

APPLICATION:

Construction of corrugated steel pipe and couplings used underground outside buildings, in storm drainage systems.

INTENT:

To limit the probability that an inappropriate coupling design will lead to:
  • entry of roots or infiltration of surrounding material, which could lead to obstruction of flow, which could lead to storm water surcharge, or
  • misalignment or separation of joints, which could lead to pipe system leakage, which could lead to soil erosion or flooding.
This is to limit the probability of water damage to the building or facility.
