According to Vastu Shashtra the suitable place of septic tank in a house North West and South East to East direction is good. It should not touch house wall and house boundary. It is two - five feet a way from the house wall.
I'm currently in the process of building a bungalow. Septic tank in this house is placed below the entrance.
Where the Septic Tank should be placed according to Vastu?
NW is best for septic tank but if not possible can septic tank place in east of plot
