An Introduction to Utilidors, Power Distribution and Communication Systems in Cold Regions

J. Paul Guyer, P.E., R.A., Fellow ASCE, Fellow AEI

A utilidor is a conduit that contains multiple utility systems such as water, sewerage, fuel oil, gas, electrical power, telephone, and central heating in various combinations or in some cases all together. They have been used at a number of installations and communities in the North American Arctic. Utilidors are very expensive and can only be justified for special situations. In most cases individually insulated pipes in a common trench or on a common pile will be more economical. Utilidors have been constructed above and below ground, and range in size from a simple insulated conduit to a walk-through passageway. New designs typically incorporate lighter construction materials than the reinforced concrete used previously at many installations.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
