permafrost

[kennedysimon]

Hi I have a house in Chamonix, at the moment i am renovating the Garage to an apartment so i need sewage pipe it, there is a lot of rock so i can only get the pipe down about 6", my main concern is the cold as it gets to -30c some times during the winter will sewage pipes freeze if it is so close to the surface.

Interesting question

I would say no, because the water would be on the move.

Permafrost is the wrong word, I think that is minus 320c

a properly fitted waste pipe will have sufficient run to empty after use so will never have water lying in it that will freeze, when the waste is in use the water will be flowing so will not freeze, so it is all down to good installation

Why are you asking that here? Ask a local expert; we don't have permafrost in England.

Am not sure about the regs in France and whether you need to use an approved installer for waste runs, or under supervision of the BCO equivalent over there. Think this is a more appropriate starting place for your enquiries.

Since when has Ireland been a part of France

You do if you install GSPH wrong

Chamonix is a ski resort in France.
No need to apologise - we're all human

permafrost is when the temperature never gets above freezing and the ice never melts..

as for moving water freezing.... they ice skate on rivers in some parts, so moving water can indeed freeze..

given that it's waste water, it will be fairly warm when it leaves and will have some sort of heat generated by the breakdown of biological waste products..

minus 320c

:S 0ºK =-273ºc so minus 320 is 47 lower than is known to man!


I reckon it will freeze if you get a dripping tap. I wonder if there is some form of trace heating that would be suitable just incase.

How have the locals dealt with drainage, since they will no doubt have been faced with the same problem.

 

[gaspro1981]

fit a saniflow and pump it to an existing soil or waste pipe
simples

The locals probably got a hammer and chisel and made it deeper

There is that of course.
