When ground has become saturated due to heavy rainfall and no more water can be absorbed, or ground is holding water in impermeable soil types like clay, the ground becomes waterlogged.
The answer is the installation of land drains using land drainage pipes.
Land drainage pipes are perforated and therefore allow water to enter them. They are placed into trenches part filled with gravel and with a gradient of ideally 1 in 150. The trenches are then back filled with more gravel or pea shingle totally encasing the pipe.
Drained water can be directed to a soakaway or a storm drain in an area where the ground is more open and allows a passage through without getting blocked. Drained water can also be directed into a stream or river where permission is first required from the Environment Agency.
