Location of CDS

Homebush Bay in Sydney
Client Requirement
For a highly visible area at Homebush Bay in Sydney, the
client wanted Best Management Practice (BMP) for installed
technology to protect the site from stormwater pollution.
A further objective was to ensure that the environs surrounding
the site would be safeguarded from sediment buildup from
earthworks during construction and from the large quantities
of litter expected in later use, to reduce their impact
on local flora and fauna. At least 95% of runoff from
this large, multi-use site was to be treated to remove
all gross pollutants, including animal waste and leaf
litter.
To meet these requirements, the client’s consultants
chose CDS technology as BMP. The CDS technology met and
surpassed the stringent selection criteria because of
its ability to trap over 99% of gross pollutants, vegetation
and sediments with be treated to remove all gross oil.
This means that ultimately, water from this protected
site will have a reduced impact on Sydney Harbour.
No other technology has been so thoroughly tested by independent
authorities to validate the claims CDS has made for it.
These authorities include the CRC for Catchment Hydrology,
Monash University, CSIRO, Thiess Environmental Services,
University of NSW and the University of Southern California
Los Angeles. CDS units capture and retain pollutants over
the full range of flow conditions. Because they are genuinely
non blocking, they maintain their high capture rate throughout
the entire rain event. This is not true of GPTs which
use direct screening.
