Water Sensitive Urban Design

Water Sensitive Urban Design (WSUD) is about integrating water cycle management into urban planning and design. 

WSUD looks to manage the impacts of stormwater from development with the aim of protecting and improving waterway health by mimicking the natural water cycle as closely as possible.

Key principles of WSUD

Protect waterways

Protect waterways within urban development’s so that they can remain valuable community assets that enhance livability and support the ecosystems that rely on them.

Manage stormwater in the landscape

Manage stormwater in the landscape rather than drain it all to waterways. This reduces the volume and frequency of stormwater drained and increases the quality before stormwater reaches waterways. 

Add multiple benefits while minimising development costs

Provide for a range of benefits such as alternate supply, improved amenity and safety, and contribute to enhanced liveability by enhancing natural features such as rivers and lakes.  WSUD minimises the drainage infrastructure development costs by reducing pipe sizes and potentially replacing other large scale reticulated water systems with local solutions.

We work closely with developers to ensure WSUD principles are considered in the design of new housing developments, whilst also undertaking projects where there is an identified need.  WSUD works include: grassed and landscaped swales; infiltration trenches and bio-retention systems; gross pollutant traps, wetlands and sediment ponds; rainwater tanks – stormwater harvesting and reuse; grey water harvesting and reuse; rain gardens, porous pavements and aquifer recharge and reuse.
