Water Distribution and Wastewater Collection Systems for Arctic Environments

摘要

The Water Distribution and/or Wastewater Collection System is specifically applicable in permafrost and cold climates in which water and wastewater systems may be subjected to freezing. The Water Distribution and/or Wastewater Collection System is applicable to domestic, industrial, recreational and institutional water distribution and wastewater collection systems including transmission, distribution and collection mains and service connections. The Water Distribution and/or Wastewater Collection System uses an pre-insulated double pipe conduit/casing containing the water and/or wastewater systems and hydronic piping or electric heat tracing. The system design is simple, practical for horizontal directional drilling and economical when compared to conventional permafrost utilidors or insulated and heat traced pipes or deep bury installations, or water bleeding to prevent freezing.
