Land Drainage is the term given to perforated drainage pipes that are utilised to cure waterlogged areas in gardens or other landscaped areas such as sports fields. They are pipes that allow water to enter through perforations. The water then flows away to a suitable disposal point such as a storm drain a stream or a soakaway. You should check with your local authority to confirm your chosen point of outfall is permissible. Land Drains shouldn’t be connected without the permission of the Local Authority to a foul or joint drain, and in these situations the connection must always incorporate a trap.
In waterlogged areas, carefully packed dirt particles hold the water position — there is no escape route for the water. A route for the water to travel through is generated, since the gap between each piece of shingle is greater than the gaps between the original soil particles by replacing most these dirt particles with granular material such as shingle. Gravity takes the water and hold picks up speed, to the land drain and channelling downwards itself via the perforations in the pipe. Once in the pipe, which is placed in a gradient, the water is then free to stream away unhindered to the point of disposal.
Although 80mm and 100mm are the most popular sizes for applications, the pipes’ diameter varies from 60mm to 150mm. Although coils are available in some of the sizes, lengths are generally 25m or 50m. A perforated Twinwall pipe should be used rather than the flexible coiled option, where there’s a need for strength in the pipe. Examples of this would be in instances such as under a driveway or where the pipe is buried down and thus the material above the pipe is heavy.
Unlike underground ducting where colour is an indicator of what is inside the duct, colour is irrelevant in regards to land drains. Most however are manufactured in either a black or a yellow colour.
