Intent 1:
To limit the probability of:
- [Clauses (a) and (b)] silting-up of the sump pit, which
could lead to the ingress of moisture from the ground, or
- [Clause (c)] excessive moisture transfer from the sump
pit into interior spaces, which could lead to high relative humidity.
This is to limit the probability of:
- compromised structural integrity of foundation walls
and basement floors, or of elements supported by the walls or floors,
or
- deterioration, which could lead to compromised integrity
of elements supported or protected by exterior foundation walls.
This is to limit the probability of harm to persons.
