Shallow Installation of Water Pipelines
This report examines the likely depth of frost penetration in the UK and the influence this may have on water mains and service pipes installed at 750 mm and 600 mm cover respectively. It also considers the effect of reduced cover depth on both standard fittings and other services within the footpath.
Some of the conclusions the report draws are that: -
It is not possible to predict with any certainty whether pipes will freeze at 600 mm or 750 mm because there is insufficient temperature information below 300 mm.
The soil type and composition has an influence on the penetration of frost, but due to the variations in soil type and structure found in the UK, it is not possible to generalise on the depths to which frost might reach.
Polyethylene pipes have a much slower rate of heat loss than equivalent iron and copper pipes and will therefore perform more favourably in severe winter conditions.
It is possible for service pipes to be connected to the side of water mains, which will afford a better f
