How does it do that?

Visual Soakaway Design 4 incorporates the best of BRE
365 and CIRIA 156. The Design methodology follows all
of the BRE 365 guidelines and includes many other features
such as "Factor of Safety", user definable failure
parameters.
The most recent release of our software includes many
new features not previously seen. For further details
on new features click here.
Visual Soakaway Design 4 designs filter trenches in
the same way that it designs soakaways, however, when
the designer chooses the filter trench option he/she must
select a percentage of the impermeable area which will
overflow out of the soakaway. In doing this, the majority
of the volume is still infiltrating into the ground with
only a predefined amount being released into the watercourse.
This attenuation protects the integrity of the watercourse
from excessive erosion.
The basic theory of Soakaway design follows the formula
shown below...
Storage = Inflow - Outflow
Where,
Storage = the amount of water that can be stored within
the Soakaway.
Inflow = the total defined runoff from the impermeable
area (taking into account the volumetric runoff coefficient
and any deduction for filter trench design, see above).
Outflow = (surface area of exfiltration) x (soil infiltration
rate) x (storm duration).
Full details of our design methodology can be found in
the Help files
here.
Yes.
Visual Soakaway Design 4 can design Filter Trenches
which give the following benefits to new developments...
- Surface water run-off from road and hard-standing
areas can be filtered within the trench, thus allowing
only a predefined volume of water to discharge to the
watercourse or surface water sewer.
- The use of filter trenches provides attenuation during
the storm event. This lessens the impact of drainage
from new developments on the watercourse thereby protecting
rivers from excessive siltation and erosion.
- Soakaways are constructed underground and, therefore,
do not impact visually on the final landscaped surface.
Yes.
Visual Soakaway Design 4 has a user-definable setting
for the Void Ratio of the soakaway. This can be set as
high as 0.95 which is comparable to that found in Stormcell
units produced by HRD Ltd.
The full version of Visual Soakaway Design 4 includes
the following features...
- Full file open/save/print functions.
- Unlimited use plus full technical support.
WebCom Systems include this disclaimer due to the importance
of maintaining the soakaway throughout its useful life.
Soakaways can become clogged with silt through time and
regular monitoring of silt levels must be carried out.
The use of a silt trap manhole at the head of a soakaway
can, however, greatly reduce the inflow of silt and suspended
solids.
As an aid to the designer, WebCom Systems now include
a maintenance schedule with version 4.
WebCom Systems will respond to all queries whether by
telephone or email in 2 working days. We can be contacted

No.
Visual Soakaway Design 4 has a visual design window which
allows designers to see a 3D representation of the soakaway
and stretch it while designing it in real-time.
We have been in the soakaway software market for over
7 years now and aim to remain the preferred supplier of
such software.
Visual Soakaway Design 4 is currently priced at £325
excluding VAT.
