Installation conditions
Cover depths with telescopic dome shaft in green
400 – 780 mm
area.
The maximum soil coverage is dictated by the
maximum length of the original shaft extension.
This must not be extended.
The tank must not be installed under traffic area.
The
tanks
must
not
be
installed
in
groundwater/ stratum water.
If it is to be expected that ground water/stratum
water could occur even just occasionally, this must
be discharged via a drain line.
As the occurrence of ground water/stratum water
is very difficult to rule out in advance, we generally
recommend the laying of a drain line.
