Many family houses or villas are located outside towns and villages. They are designed to suit the needs of family houses, villas, chalets, small hotels, shops or other public facilities and are especially suitable for buildings which are not occupied all year-round or operate seasonally. Septic tanks are installed in areas where there is no central sewage.
Patented back in the 1900s, the septic tank has developed as technology and nowadays modern models are made of precast concrete, concrete blocks, polyethylene, fiberglass or steel.
By definition a septic tank is container in which waste matter is decomposed through bacterial action.
