If you live outside major urban centers or if you own a home away from the centre of a municipality, then you must use a septic tank. Although these facilities do not require excessive maintenance, it is very important to ensure their proper functioning by being alert to signs of malfunction. By doing so, you avoid all inconveniences and unnecessary expenses related to the repair or replacement of your septic tank. Besides, be aware that a defective sanitary installation can not only cause many costly problems, but also lead to pollution of lakes and source of drinking water.

Septic tank functions

A sanitary evacuation system consists of two devices: the septic tank and the septic field (also called tile bed). The role of the septic tank is to liquefy solids, by settling and fermentation through the action of anaerobic bacteria. As solids settle to the bottom of the tank in he form of sludge, the scum floats to the surface. The disposal field, meanwhile, continues the purification of wastewater through the action of bacteria that digest and eliminate waste such as solids in suspension. Once the process is complete, the filtered wastewaters infiltrate the soil.
