A sump pump is a pump used to remove water that has accumulated in a water collecting sump basin, commonly found in the basement of homes. The water may enter via the perimeter drains of a basement waterproofing system, funnelling into the basin or because of rain or natural ground water, if the basement is below the water table level. Sump pumps are used where basement flooding happens regularly and to remedy dampness where the water table is above the foundation of a home.
In Winnipeg, the installation of sump pumps into new construction homes became mandatory as of 1986. All residential homes built from that point onward had to incorporate the above described system into their construction.
There are pros and cons with this system: While it keeps rainwater out of the sewer systems, (thereby minimizing incidents of sewer backup), this new sump system only works as long as there is electricity.
During heavy summer rain-storms, when electrical power is prone to failure, a sump pump can fail at the exact worst time. In inoperative sump pump results in rainwater entering your basement.
