The potential benefits of installing the
ORC units, currently being put to the
test in a large trial project by a major
Melbourne water retailer, are massive.
If the reduction in rapid flow
infiltration to sewers via an overflow
relief gully is as high as the 40%
estimated by the PIC, the savings in
capital expenditure will be as high as
$4.5 M. The selected trial area is a
development of 2000 lots, each of which
is to have an ORC installed.
Rapid flow infiltration explained: Once
a heavy rain event begins, studies show
that peak wet weather flow of the sewer
system is reached very quickly as shown
in the diagram; Calculate the benefits
based on the chart above if 40% is
reduced. Melbourne sewers run
approximately 6 times normal in such
instances and in Australia’s north up to
20 times the normal flow is experienced.

infiltration overflow relief device can

The ORC is very good
news for you too-
1. In a new
connection it can be
placed lower then a
normal ORG which can
potentially save an
entire course of bricks
per house.
2. On an average
brick beneer house,
after device and
installation costs are
covered, there is a
potential net saving of
more than $500!
3. It is easy and
quick to install.
4. The ORC is
designed to be installed
into the normal ORG.
5. The ORC can be
easily retrofitted to an
existing ORG.
