Solids and liquids separate in a septic tank with the liquids receiving minimum biological treatment. The liquid in the centre of the tank is discharged via an outlet before passing through a soakaway system which must be installed to national standards. The solids that gather at the bottom of the tank must be emptied regularly to prevent overflow and potential soakaway damage.

So-called because these products bring together all the requirements to treat wastewater to a high standard within a single pre-fabricated system. Generally consisting of a two or three chamber treatment process, effluent is treated aerobically, ie, using oxygen, to such a standard that it is usually acceptable to discharge directly into watercourse.

Sewage treatment plants require an electrical connection and should be emptied regularly dependent on usage and capacity.
