Telford Soakaway Replacement
Blocked Soakaway In telford ?
Soakaway problem in Telford ? Soakaways are deep holes in the ground usually filled with gravel or rubble. Rainwater runs into the Soakaway and fills the cavities between the infill material, this water is then gradually absorbed into the surrounding ground.
For the Soakaway to work efficiently and over a prolonged period of time, the water going in should be clean and free of debris such as leaves and moss which cause restriction and blockages and can result in the soakaway having to be dug out and renewed. It is possible to fit a filter to the rainwater system to prevent the entry of debris.
A wastewater soakaway is the section of a drainage system that follows from a septic tank or sewage treatment plant. The purpose of a soakaway is to allow the liquid waste that has left the septic tank to percolate through the soils surrounding the pipework – the soakaway pipework is often perforated or slotted to enable this to happen.
The purpose of a filter is to stop debris entering the soakaway, if a filter is not used leaves and moss can block the soakaway.

The crates are wrapped in geotextile membrane and surrounded by pea shingle to allow water in and out.
