As per Vastu it is important to place septic tank at the right place and in right direction at home. Septic tanks are often made randomly with no consideration which however causes various problems to occupants. The origin of septic tank can be traced back to decades when family members preferred having their own water tanks. It was always considered an essential element in every house. The pit for a septic tank was always dug and hence the importance of Vastu came into being. This pit needs to be dug in a perfect manner failing which could encounter serious health and wealth problems. Today septic tanks have been replaced by water or overhead or automatic water tankers. However, septic tanks are still considered in villages and semi-urban areas.
