Water Sensitive Urban Design/Development
Research on the opportunities and barriers to WSUD adoption in the Botany Bay Catchment was carried out in late 2007 as a part of the BBCCI.
A short final report (30 pages) detailing the findings was prepared in December 2007.

During the research into the barriers and opportunities to WSUD adoption in the Botany Bay catchment one of the highest rated opportunities was to provide councils with a model WSUD/Stormwater clause that could be included in their LEPs. The BBCCI has developed a model clause based on DECC’s recent advice to councils, which local councils can consider during the development of their LEP’s. The document is very short (2 pages) and includes a one page introduction sheet. It was prepared in June 2008 and can be downloaded below.

A water sensitive urban design (WSUD) adoption strategy has been prepared for the Botany Bay Catchment. It gives a good snapshot of the levels of uptake of WSUD by councils throughout the catchment along with those expecting to include WSUD in future planning policies.

What is Water Sensitive
Water Sensitive Urban Design/Development (WSUD) is
a new way of planning and designing urban environments
that is sensitive to the issues of water sustainability
and environmental protection.
The term combines two elements – “water
sensitive” and “urban design”. Urban
design is a well recognised field associated with
the planning an architectural design of urban environments,
covering issues that have traditionally appeared outside
of the water field but nevertheless have implications
for environmental impacts on land and water.
WSUD brings “sensitivity to water” into
urban designs. The words “Water Sensitive”
define a new way to integrate urban water cycle management
that involves the various disciplines of engineering
and environmental sciences associated with the provision
of water services, including the protection of aquatic
environments in urban areas. Community values and
aspirations of urban places necessarily govern design
decisions and therefore water management practices.
Collectively WSUD tries to integrate the social and
The key objectives of WSUD include:
- Reducing potable water demand through water efficient
appliances, rainwater and greywater reuse.
- Minimising wastewater generation and treatment
of wastewater to a standard suitable for effluent
reuse opportunities and/or release to receiving
- Protect and restore aquatic ecosystems and habitats
- Treating urban stormwater to meet water quality
objectives for reuse and/or discharge to surface
- Preserving the natural hydrological regime of
- Protect the scenic, landscape and recreational
values of waterways
- Reducing minor flood risks in urban areas
For the Botany Bay Catchment and this Coastal Catchments
Initiative WSUD is likely to be one of the key solutions
to improving water quality (particularly stormwater
quality) and minimising ecological impacts on the
Bay and its waterways. It requires a shift in thinking
so that stormwater is viewed as a valuable resource
rather than a nuisance.
What does WSUD look like
on the ground?
WSUD requires an individual design approach to each
site and as a result there isn’t a combination
of solutions or devices that will be “right”
in each situation. The unique characteristics and
intended uses of each site will determine what WSUD
solutions are best included into the design. Below
are some examples of what has been done by local councils
and developers in the Botany Bay Catchment.
These are a few examples of WSUD in the Botany Bay
This is a bioretention system that treats the stormwater running off the roadways in
this development at Victoria Park in Zetland.
This is wetland that is also treating stormwater
from a very industrialised area at the top of the
Cook’s River in Chullora.
This is a commercial building in Loftus and it has
permeable pavements on the carpark and a bioretention
system to treat its stormwater. This building also
captures the rainwater that falls on its roof and
stores it in below ground rainwater tanks to be used
to flush the toilets throughout the building. This
building was developed and is owned by Sutherland
