Sump Pump
The sump pump system is designed to capture water that enters the
basement or crawlspace and redirect it away from the home. The basic
sump systems include a sump pit, a sump
pump, float or switch and drain
line. The sump pit extends below the slab and collects the
surface water that enters the basement/crawlspace or groundwater that rises
to the slab.

When the water in the sump pit rises to a preset level, a
float rises or pressure switch activates the sump pump. The water is then
pumped through a drain line to either a storm sewer, dry well or the
exterior, away from the foundation.
Trenches and Troughs
Trenches and troughs are depressions in the foundation floor
that collect and funnel water to a specific location and are sometimes used
to direct water to a sump pump. In crawlspaces, trenches are usually
dug into the dirt floor. In basements, perimeter drain troughs are
created at the junction between the slab and foundation wall.
