Every basement in Winnipeg should have a drainage system, if the drainage system is contained under the basement floor slab, this is called an interior drainage system, if the weeping tile is situated on the outside of the basement wall, this is called an exterior drainage system. The core of the system is the weeping tile, and the system is based on gravity, the lines are graded and drain to the lowest point in the system, this is usually a sump pit and pump, or a catch basint, AKA basement drain.
In older homes. the weeping tiles drain towards the catch basin, in newer construction the weeping tiles drain towards the sump pit. Not all sump pits are equipped with an overflow. In homes retrofitted with sump pits, unless major alterations to the basement drain, in the form of diverting the weeping tiles from the catch basin to the sump pit are undertaken, the weeping tiles are usually left in place draining towards the catch basin.
Diverting the weeping tiles from the catch basin to the sump is usually cost prohibitive as a greater area of floor must be removed for room to allow the tiles to run to the new pit.
This is a simple 3 inch pipe run level from the catch basin to the sump pit. Anything overflowing or backing up from the basement drain will be caught and diverted to the sump and pumped out. You may never know you have had a sewer back up unless you inspect your sump pit regularly, This is front line defence against sewer back up.
