    Septic Systems: A Brief Overview

    A septic system is a small-scale sewage treatment system, primarily found in areas without centralised sewer systems. At its core, it’s a simple yet effective mechanism, treating wastewater from household plumbing, including bathrooms, kitchen drains, and laundry. So how does it do this?

    Septic Tank

    This buried, watertight container typically made from concrete, fibreglass, or polyethylene receives the wastewater from the home. Its primary function is to hold the wastewater long enough for solids to settle down (forming sludge) and oil and grease to float to the surface (as scum).


    After the primary treatment in the tank, the liquid wastewater exits into the drain field. This component is crucial, as it provides secondary treatment, with the soil acting as a natural filter.

    The Science Behind It

    Biological Processes: The magic – or rather, the science – happens when microbial life inside the tank begins to break down the organic material. This biological process is crucial, turning potential pollutants into harmless by-products.

    Separation Mechanism: As wastewater enters the tank, its solid component settles at the bottom. Over time, the microbial action breaks down these solids into sludge. Meanwhile, the fats and oils float to the top, creating the scum layer.

    Natural Filtration: In the drain field, the soil plays a pivotal role. As the effluent percolates down, harmful bacteria and viruses are naturally removed. This clean, treated water then safely re enters the groundwater system.
