The
different design versions are based on the German ATV Standards
ATV-A 117 and ATV-A 128, basicallly there are systems integrated
in the sewer main or as a bypass system. Profileen stormwater
retention tanks are used as:
- Collection basin
- Pass trough basin with overflow
- Series-flow basins
- Retention tank with discharge at inlet or outlet
- Parallel tanks as treatment- or storage battery
PROFILEEN
® retention tank systems are made of single components.
There is a range of (standard) components starting with simple
pipes and ending with manholes including all installations which
can be delivered with a diameter of 300 mm up to 3500 mm. To
cover standard applications we have a complete system on stock.
In the following there is a list of standard components:
inspection-
and throttle manhole
pumping shaft
discharge shaft
central
overflow
horizontal
discharge
overflow to one side
overflow to both sides
The
discharge manhole is the central element of a stormwater retention
tank. Our solutions in plastic have its advantages for the overall
costs for the installation as well as for the maintenance of
the stormwater retention tank once it is in operation.
Together with the University of Essen we developed the hydraulic
design for central overflows. The speed of the sewer in the
discharge can be influenced by the design to reduce the solids
going into the discharge.
Compared with the horizontal discharge the overflow to one side
as well as to both sides is a cost effective alternative which
is second to none for small discharge volumes.
