Water Sensitive Urban Design (WSUD) focuses on managing stormwater in a way that protects local waterways, reduces runoff, improves water quality, and supports sustainable urban environments.
Many councils now require a WSUD Assessment as part of the planning permit process for residential, multi-unit, commercial, and subdivision developments.
We prepare council-ready WSUD Assessment and Compliance Reports that clearly demonstrate how your project addresses stormwater quality and sustainability objectives — without over-complicating design or construction methods.
We assess your development using recognised WSUD performance frameworks (such as MUSIC/BESS/STORM tools), addressing:
| WSUD Element | Key Focus Areas |
|---|---|
| Stormwater Quality Improvement | Reducing pollutants (sediment, nitrogen, phosphorus) entering the stormwater network |
| Flow Management & Retention | Reducing runoff rates and volumes at the source |
| Rainwater Harvesting & Reuse | Storage tank sizing, roof catchment efficiency, reuse strategy |
| Permeable Surfaces | Paving selection and infiltration design |
| Vegetation / Landscaping | Improving urban ecology and microclimate |
| Treatment Devices | Swales, rain gardens, infiltration trenches, bioswales, wetlands |
Our approach balances environmental outcomes with practical construction solutions suitable for builders and landscapers.
WSUD Assessments are commonly required for:
Multi-unit townhouse developments
Apartment and mixed-use buildings
Commercial and industrial properties
New subdivisions and infill development
Residential projects exceeding council runoff / hard-surface thresholds
If you’re unsure whether your project requires WSUD, simply send your drawings — we will confirm instantly.
Your WSUD assessment package includes:
Council-compliant WSUD Report
STORM / MUSIC / BESS Scorecard Outputs (where required)
Sizing and specification of rainwater tanks, permeable paving or biofiltration
Drainage and stormwater strategy recommendations
Mark-ups for architectural & landscape plans
Support responding to council comments or RFIs
We work directly with your architect, civil engineer, landscape designer, or builder to ensure seamless integration with design and documentation.
Reports designed to pass council review smoothly
Clear design guidance, not just technical calculations
Practical recommendations suitable for real-world construction
Fast turnaround on urgent applications
Experienced in residential, commercial and subdivision WSUD requirements
We help you achieve compliance without over-engineering or unnecessary cost.
