A soak away is an area, usually underground, that is used to dispose of surface water runoff or purified septic tank effluent. It does this by allowing it to drain into the soil, making it unnecessary to install pipework or tanks to collect it.
The size and nature of a soak-away can depend on a number of factors, including:
- the porosity of the soil i.e. how easily the water will drain through the soil and how likely it is that it will fail to drain during times of heavy rain or snowmelt;
- the size of dwelling; the number of inhabitants; what the ground surface is covered with and what activities they carry out regularly; plus the volume of water that the soak-away will be required to disperse.
Most simple soakaways are large gravel-filled pits at least 5 metres away from the building foundations. Those that are required to cope with larger volumes of water, are often reinforced concrete chambers. These are perforated on the lower sides, and at the bottom, to let the water soak away into the surrounding soil. These are usually set well away from any buildings.
A more modern approach is to install Aquacell crates for disposal of rain and surface water or package soakaway pipes for discharges from septic tanks
