3 Domestic Well Construction

This section provides an overview of the most common types of domestic wells. Domestic wells are usually classified based on their construction method, for example a drilled well or dug well. Terminology used to describe well type varies from region to region around the world, however, the terms used in this book are widely used in Canada and the United States.

There are numerous domestic well types and construction methods available, each of which are suited to specific well diameters, depths, and geologic conditions. Well construction cost and the local availability of well construction equipment are important factors for determining how a domestic well is constructed. In general, the deeper the well, the more expensive it is to construct because drilling and well casing are usually charged by unit length.
