Soakaway Problems

Does your property have soakaway problems? 

Is your soakaway drain blocked?

Firstly, it is important to note that a soakaway for rain water is different to a soakaway system designed to carry wastewater.  Rain water soakaways normally consist of a chamber made of bricks, concrete or crates, and are unsuitable for use in wastewater systems.  This page deals with soakaway problems relating to waste water only.

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 tank to percolate through the soils surrounding the pipework.  The soakaway pipework is often perforated or slotted to enable this to happen.  The process of the liquid waste percolating through the particles in the soil provides a form of treatment of the waste, and it is then safely dispersed into the surrounding sub soils.

Soakaway systems vary in size, which depends on three key things:

  1. the size of the property
  2. the volume of waste the system is designed to process
  3. the porosity of the surrounding soil (this is measured by undertaking a percolation test)
