A sump pump usually stands in a sump pit--a hole with a gravel base about 2 feet (60 cm) deep and 18 inches (45 cm) wide --dug in the lowest part of your basement or crawlspace. As the pit fills with water, the pump turns on.

Just like the well point method, wells are drilled around the excavated area, but the diameter of wells in this case varies between 150-200mm. By creating deep wells around the vicinity, the ground water is made to fall into them under the influence of gravity.
