What is the purpose of a soakaway?

How deep must a soakaway be?
How deep should a soakaway be? The Perforated pipe should be laid at a minimum depth of 200mm and a maximum depth of 700mm. This enables aerobic contact between the effluent and the drainage stone and soil particles. This leads to aerobic digestion and effectively treats the effluent.
How do I find out where my soakaway is?
The easiest way to find a soakaway is to follow the rainwater downpipes from your house and see how far they go. Often, the downpipes from your home will lead to a sunken area on your lawn. You need to be eagle-eyed, however, as soakaways are installed discreetly, so they can be hard to find.

A deep bore soakaway is a special type of rainwater soakaway consisting of a conventional chamber and a narrow bore perforated liner extending to the infiltration medium. These types of soakaway are useful where a very good infiltration medium underlies a deep layer of poor infiltration material, such as gravels underlying a deep layer of clay.
What are the drainage standards for a soakaway borehole?
The proposed soakaway borehole must meet the drainage standards for soil infiltration and storage emptying. This includes the distance of at least 1m from the bottom of the construction to the top of the groundwater level, at any time of year, to avoid exceeding the ground’s soakage capacity.
What is a soakaway and how is it constructed?
It’s constructed by digging a small hole, then inserting a cylindrical chamber with perforations or filling it with rubble, which allows the water to drain into the soil. As the alternative name ‘ deep bore soakaway ’ suggests, this type is inserted much deeper into the ground.
