Utilidors (Arctic towns)
From Wikipedia, the free encyclopedia
Utilidors are above-ground enclosed utility conduits that are used in larger communities in the northern polar region where permafrost does not allow the normal practice of burying water and sewer pipes underground. They can in particular be found in Inuvik, Northwest Territories and Iqaluit, Nunavut. Not all older homes are connected and rely on trucks to deliver water and remove sewage.
Utilidors may also be used to carry fuel lines such as natural gas. They are not normally used to carry wiring for electric, telephone and television service, which are usually conveyed along poles.
