The concepts related to the design, construction and operation of infrastructure components for the delivery of water, the removal of liquid and solid wastes, and the provision of power for services are relatively new in the extremely cold environment found in the far north or south. The objective of this monograph is to introduce the basic principles of cold region environmental engineering. While it does not cover the basics of the environmental engineering field, it does present a great deal of introductory information related to cold regions engineering and the special geotechnical considerations that influence the design of utilities systems. The book is divided into 17 different sections that cover such topics as: planning, geotechnical, and thermal considerations; water source development; water storage; wastewater collection; utilidors; central facilities; remote camps; fire protection; and energy management. There are also appendices that provide additional information on piping options, vehicle-haul systems, snowdrifting and snow loads, and freeze protection.
