Insertion and filling

The tanks must be inserted, impact-free, into
the
prepared
trench
equipment. To avoid deformities, the tank is
filled 1/3 with water before filling in the tank
surrounding.
Afterwards
the
surrounding
gravel, max. grain size 8/ 16) is then filled in
layers of max. 30 cm steps and is
compacted.
The individual layers as well as the
medial support column must be well-
compacted (manuel tamper). Damage to
the tank must be avoided during compaction.
Mechanical compaction machines must not
be used under any circumstances. The
surrounding towards the trench must be at
least 100 mm wide.
5.4

Routing connections

All feed and overflow pipes must be routed
with a decline of at least 1% in the direction of
flow (possible, subsequent settling must be
taken into consideration in this case). If the
tank overflow is connected to a public sewer,
this must be protected against reflux by
means of a lifting station (mixed sewer) or
reflux seal (pure rainwater sewer) according
to DIN 1986.
All suction, pressure and control lines must be
routed in an empty pipe, which must be routed
as straight as possible, without bending, to the
tank with a decline. Necessary bends must be
formed using 30° moulded sections.
Important:
The
empty
connected to an aperture above the max.
water level.
