Bacteria for septic tanks, cesspits and domestic treatment plants
Biological products contain selected microorganisms and enzymes that help break down organic matter. The choice depends on the type of system: a holding cesspit, a septic tank and a domestic treatment plant each have different conditions. See which product suits your use.

Cesspit
A sealed holding tank. Nothing flows out; the contents are emptied regularly. Bacteria help break down organic matter and reduce odour, but do not replace emptying.
Septic tank
A settling tank. Solids sink to the bottom and bacteria break them down without air. Pre-treated water flows to a soakaway or a further treatment stage.
Domestic treatment plant
A biological plant with aeration and activated sludge. It runs according to the manufacturer’s operating rules and permit conditions. If problems arise, its technical condition must also be checked.

Why a septic tank smells and how to help it
A septic tank works thanks to bacteria. When chemicals, overloading or a long break weaken them, you get odour, floating sludge and a clogged soakaway.

All three collect wastewater from the house, but each works differently. That changes how you look after it and which biological product to choose.
