What are WSUD solutions? What do they look like?
The water sensitive 'solutions set' includes planning and management activities that ideally integrate:
- across catchments at different spatial scales (from across an LGA to a single site) span
- across different stages of urban development - from the strategic to detailed design.
| LGA scale |
Subdivision, neighbourhood and precinct scale |
Individual lots (residential, commercial, industrial etc) |
Strategic phase plans such as:
• Catchment Strategies
• Land Use Planning
• Settlment / Urban release planning
• Riparian Open Space planning
• Riparian Asset Plans |
Masterplanning to consider issues such as open space, streetscape, drainage and lot configurations.
|
Water smart site plans and designs |
| Integrated Water Supply and Demand Planning |
Alternative sources for water supply:
• Potable water
• Harvested rainwater
• Harvested stormwater
• Recycled and treated wastewater
• Aquifer Storage and Recharge |
• Greywater reuse
• ‘Non potable’ water for non potable uses - outdoors, laundry, toilets, industry wash down and process water etc. |
Water efficiency programs and projects
|
Water efficient facilities.
Stormwater retention, harvesting and reuse projects. |
• Water efficient homes, flats, gardens, business and industry
• Rainwater tanks |
•Stormwater management development objectives and controls
• Stormwater and drainage capital works plans
• Stormwater asset management plans
• Street Sweeping service provision
|
• Retain riparian corridors and greenspace between impervious surfaces and natural waterways
• Stormwater detention measures
• Stormwater Treatment Train: Gross Pollutant and sediment Traps; vegetated stormwater treatment systems (eg: swales, bioretention, infiltration measures, constructed wetlands).
• Sediment and erosion control during construction and establishment.
|
• Increase infiltration, reduce impervious surfaces, porous paving etc.
• Simple landscaping strategies – runoff infiltration,
• Low nutrient gardening, small scale stormwater treatment eg. raingardens
• Rainwater tanks (additional volume for stormwater retention).
• Sediment and Erosion control
|
Education and engagement, community planning, community bushcare, landcare, creekcare groups.

HCCREMs'
Water Smart Model Planning provisions offer a framework by which all of the above elements might integrate for a given council.
