Method Of Statement For Burial Of
Septic Tank/Holding Tank

1.Excavate the land where bury the tank as per the dimension of the tank.

2.Use sand for filling the tank.

3.Firstly fill the sand in both sides equally.

4.After completed the side filling only cover the tank completely with sand. We recommend 30 cm to 40 cm sand on top of the tank.

5.Vehicle is not allowed to pass through the buried tank.

6.Do not use mud for burring the tank because if the tank over flowing, mud will become wet and increase the load, will not sustain the tank.

7.For making manhole on top of the tank, first apply minimum 4" thick concrete then start brick work.

8.Do not allow to over soak the tank.

9.Remove waste water periodically.

10. Do not remove Air-Vent from the tank without manufacturer's instruction.
