How it works
In the early stages of a storm event the flow passes through
the system unrestricted. The patented distribution pipework
below the Stormcell® blocks are part of the stormwater network
and carry suspended particles and debris directly through the
system. Each Stormcell® block has a woven geotextile layer
on the top and bottom as a secondary defence against the intrusion
of fines.
As flow increases during heavier storm events Hydro International’s
Hydro-Brake® Flow Control restricts the outflow, forcing
excess water through the perforations in the distribution
pipework and into the granular layer and Stormcell® blocks.
At the end of a storm event the stored water drains back through
the granular layer, into the perforated pipework and on through
the control manhole.
