Collection & Treatment of Sewage

For dwellings without mains drainage, Septic Tanks provide a traditional solution to sewage disposal needs. Sewage enters the Septic Tank into a settlement chamber, allowing solid waste (sludge) to sink and liquid to rise to the surface. The surface liquid makes contact with oxygen and the organic matter starts to break down biologically. This liquid still contains sewage but in small enough particles to be carried through the discharge outlet and into the ground (soakaway).

Why do I need a septic tank?

Basic Septic Tanks only partially treat sewage and discharge effluent of low quality. Many authorities in the UK prohibit their use. More advanced products like the Entec SuperSpetic, offer a much higher level of effluent quality, but in all instances a Sewage Treatment Plant should be considered as the first option.

Septic Tanks may be installed (subject to consent) in applications where:

  • Soil is of suitable porosity.
  • Installation complies with Building Regulations (Approved Document H).
  • The installation will not contaminate any ditch, stream or other watercourse.
