WSUD: Water Sensitive Urban
Design
This series is a tour of locations in the Peel-Harvey catchment
that showcase different methods of acheiving better urban water
management outcomes more details of which can be obtained at
this site. The practices employed at each site are a
direct response to the conditions and constraints of each
site. They were chosen to achieve the objectives of water
sensitive urban design while supporting the urban and community
vision for each development.and are an initiative by the
Peel-Harvey Catchment Council aimed at improving management of our
water resources.
Water sensitive urban design is a philosophy for holistic
management of urban water resources. It provides a framework
for minimising the impact of urbanisation on the natural water
cycle. Water sensitive urban design addresses water quality,
water quantity and water conservation, together with broader social
and environmental objectives within the context of urban planning
and development.

This key factor in the design of the North Port development was
the acheivement of water sensitive urban design objectives to
minimise the impact on the Peel inlet.
Key site objective :
- Maximise local infiltration
- Diversion and detention of first flow runoff (which contains
high amounts of polutants).
- Minimising the amounts of impervious areas to increase
infiltration
- Integration of stormwater treatment systems into the urban
form
- Minimise runoff velocities to prevent erosion
Best management practices include :
- Incorporation of weap holes, aggregate (metal bed) and traps
within all gully and side entry pits to maximise local
imfiltration, detain all first flow runoff and minimise the volumes
and area required for detention basins (A)
- Over depth manholes and proprietry drainage cells to achieve a
"no flow" system of infiltration (B)
- Incorporation of swales to facilitate stormwater treatment and
infiltration (C)
- Flush kerbing where adjacent to public open space areas or
large medians, to direct stormwater to infiltration areas (D).
Other objectives include :
- Design of public open space to accommodate infiltration of
stormwater without detriment to pablic amenity or environmental
values (E)
- Retention of existing local native bushland and landform to
reduce and filter runoff (F)
- Conservation of water through minimising turfed areas (G)
