Effluent ~ can be defined as that which flows out. In building
drainage terms there are three main forms of effluent:-1. Subsoil Water ~ water collected by means of special drains
from the earth primarily to lower the water table level in
the subsoil. It is considered to be clean and therefore requires
no treatment and can be discharged direct into an approved
water course.- Surface water ~ effluent collected from surfaces such as
roofs and paved areas and like subsoil water is considered to
be clean and can be discharged direct into an approved water
course or soakaway - Foul or Soil Water ~ effluent contaminated by domestic or
trade waste and will require treatment to render it clean
before it can be discharged into an approved water course.
