of the septic tank allows liquid to be separated from solids. The solids settle to the floor of the tank whilst fat and grease
will float to the surface and form a crust. The liquid waste then drains to a soakaway, where it filters and percolates into
the surrounding soil.
As a septic tank relies on a soakaway
as part of the filtration process, its effectiveness can be greatly reduced by surrounding ground conditions, i.e. high water
table, clay soil and contamination. In these problem areas it may not be possible to install a septic tank and a sewage treatment
plant may be required.

convert existing septic tanks/cess pits into sewage treatment plants avoiding invasive and expensive groundworks.
