septitankissa

Septitankissa is a Finnish term that refers to a septic tank. A septic tank is an underground structure, usually made of concrete, fiberglass, or plastic, that serves as a primary treatment for wastewater from homes or buildings that are not connected to a municipal sewer system. The tank receives wastewater from toilets, sinks, showers, and laundry. Inside the septic tank, solid waste settles to the bottom, forming a sludge layer, while lighter materials like grease and oil float to the top, creating a scum layer. The liquid wastewater, known as effluent, remains in the middle.

The septic tank's primary function is to separate solids and liquids. Bacteria present in the tank begin to break down some of the organic matter in the waste. However, the treatment is incomplete, and the effluent still contains a significant amount of pollutants. This effluent is then typically discharged to a secondary treatment system, such as a drain field or leach field, where it undergoes further natural purification by soil and microorganisms before reaching groundwater. Regular maintenance, including pumping out accumulated sludge and scum, is essential for the proper functioning of a septitankissa and to prevent system failures. The frequency of pumping depends on the tank's size and the amount of wastewater it handles.
