An Intro to Utilidors in Cold Regions

Course Description:

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.

Learning Objectives:

Upon successful completion of this course, participants will be able to:

• Understand the pile supported and in-ground utilidors
• Know the hot water and steam lines in utilidors affect other utility lines and cables
• Understand the cross-connection control
