Well Anatomy

A water well is a hydraulic structure which economically and efficiently withdraws groundwater from a water-bearing formation.

The design and installation of a water well is dependent upon a wide variety of factors, but mainly upon the underground geologic environment in which the water well is completed. For this reason, it is highly recommended that all wells should be designed and installed by qualified professionals.

The following drawings depict typical water well installations for the hydrogeologic conditions common in Canada:
