1 Inspect all materials for defects prior to installation.

2 Maximum depth of bury from the nish grade level to the top

of the tank is 24”

3 Excavate hole a maximum of 12 inches larger than the tank that

is being installed. Dig hole for accurate sizing. This reduces the

distance between the tank and undisturbed soil. It also provides

good support for the exterior tank wall.

4 Place 6-12 inches of sand into bottom of excavated hole and level

tank.

through man holes.) Carefully lower tank into the center of the

excavated hole and seat into the sand base.

7 Continue back lling the excavated hole with sand or free-owing soil.

8 Fill evenly around the tank with sand or free-owing soil and compact

as you ll. Check for level.

9 Compact backll under inlet and outlet pipe.

10 Complete backll to within 6” of nished grade. Complete installation

with topsoil. Mound the soil over septic tank to provide positive drain

age away from the tank. This will also help to allow for soil settling.

Install lids on risers, immediately after installation.
