The Water Distribution System is specifically applicable in cold climates in which water distribution systems may be subjected to freezing during the winter months.The Water Distribution System is applicable to domestic, industrial, recreational and institutional water distribution systems including water transmission and distribution mains and service connections.The Water Distribution System has applications in specific terrain and climatic conditions such as high bedrock, high groundwater table and permafrost.The Water Distribution System may, in specific terrain and climatic conditions, use uninsulated or insulated water mains and service connections, but without heat tracing or water bleeding in any case.The Water Distribution System is applicable to single and multiple complex distribution pipe systems arranged as parallel or looped, or combination of both arrangements.The system design is simple, practical and economical when compared to conventional design of insulated and heat traced pipes or deep burry installations, or water bleeding to prevent freezing.
