Soakaways

Soakaway Buckinghamshire

A soakaway can have various meanings when associated with land drainage. In this instance, the soakaway is one connected to a septic tank or sewage treatment plant. If a septic tank is the heart of your sewage system, the soakaway is the lungs. The soakaway allows the liquid to drain off from the septic tank into the sub soil naturally.

The size of the soakaway will be dependant on the following factors:

  • The porosity of the sub soil material.
  • The size of the property and the number of residence it is serving.

The soak-away is the final process in the septic tank system as the waste water filters into the surrounding aerated subsoil a biological treatment occurs, any septic tank is only as good as it”s soakaway and a poorly installed soakaway will not only fail and block the entire drainage system but they can also pollute water courses, rivers, brooks and the surrounding subsoil, and you may well end up with a large pond of sewage in the middle of your lawn.

Common septic tank soakaways are constructed via long trench lines filled with a clean stone and have a slotted or holed distribution pipe. These trenches can be interconnected (a looped system), a simple long trench, a herring bone layout or a large filled pit.

Most soakaway will last a lifetime if the correct emptying and maintenance of the septic tank. However if you do not empty your tank on a regular basis the solids from your tank will be forced down your soakaway clogging the pipes and contaminating the soil making the soakaway no longer effective.

One this has happened the soakaway comes to the end of its life and a new soakaway must be installed. The main way to see if your soakaway pipes are blocked or contaminated is by the frequency your tank fills. If you find that your tank is filling fast especially after heavy rainfall and that the water is not dropping then its a good chance your soakaway is damaged.
