Intent 1:
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.
