PREPARING THE PIT AND INSTALLATION SUBSTRATE

INSTALLATION ON SLOPES
Tanks must never be installed on loose ground, on slopes, against embankments which generate a load on the
tank, or in positions where rainwater is channelled.
In situations of this kind it is essential to call in an authorised engineer who will recommend the right procedures
for overcoming the problem.
Non-permeable ground
Reinforced concrete plinth
ENGLISH
DO NOT HANDLE THE TANK EVEN WHEN PARTIALLY FULL.
DAB PUMPS tanks must only be used buried in the ground. Do not use
above ground.
In the event of use above the ground, comply strictly with the instructions
provided in the "Installing tanks above the ground" section.

PIT
Pit size
Prepare a flat-bottomed pit of suitable size with self-supporting sides, so that
there will be a gap of about 30 cm all around the tank.
Drainage.
On clay or silt soils which are not permeable to water, a drainage system
should be provided to prevent variations in the pressure applied to the tank in
different points due to the build-up of water in the pit after rainfall.
If no drainage system is present and one cannot be created to drain the water
from the bottom of the pit, follow the instructions provided in the "Pits with
groundwater present" section.
Type of ground.
If the ground is not uniform, a reinforced concrete plinth of suitable strength,
calculated by a qualified engineer, must be provided in the bottom of the pit.
