Buried mains and sewers freeze in summertime and become solid ice in winter in permafrost areas; protection by heating is difficult, as melted permafrost performs like quicksand; N.M.Hall's continuous flow, two pipe heated water system at Flin Flon, Man, prevents freezing if velocity of flow is about 3 ft; U S Army at Fairbanks, Alaska, uses single-pipe system; utilidor sewer construction; ice coating prevents natural digestion in water; continuous flow, heating of pipes, and insulation, preferably by outer container, around pipe is essential.
