2.4.2. Slope, embankment, etc.
During the installation of the tank in close proximity (<5 m) to a slope, mound or
embankment (greater than 5°), a statically calculated retaining wall must be built to
absorb the active earth pressure. The wall must exceed the tank dimensions by at least
500 mm and must have a minimum clearance of 1000 mm to the tank.

2.4.3. Ground water and cohesive (water-impermeable) soil (e.g. clay soil)
The tank must only be installed into groundwater/stratum water up to the levels specified
in the following table. If it is to be expected that groundwater/stratum water levels - even
if only occasionally - exceed these levels, it must be drained.
The drainage line may end up in a vertically installed DN 300 pipe, equipped with a
submersible pressure pump that drains the excess water. The pump must be inspected
in regular intervals.
