Description:

The Septic Tank is the most important component of the entire system, what goes into the tank directly effects how the system performs. The function of the Septic Tank is to allow separation of the solids from the sewage so the remaining liquid (clarified effluent) can be absorbed into the ground without clogging the soil.

Within the tank illustrated above, three important processes take place. The heavier solid particles in the sewage settle to the bottom of the tank, forming a layer of sludge. Lighter materials, including fats and grease, float to the surface, forming a scum layer. Bacteria (called anaerobes, because they live without oxygen) live in the Septic Tank and slowly digest some of the solids into gaseous and liquid components. This helps to reduce sludge build up.

Sludge and scum are stored within the tank rather than being allowed to flow into the disposal field where they would quickly clog the soil, causing the disposal field to fail. As the tank fills with sludge and grease, efficiency of treatment decreases. Sludge and scum are removed when a Septic Tank is pumped.
