WSUDP APPROACH ON DIFFERENT SCALES 1 WATER-SENSITIVE PLANNING (CITY/ZONAL SCALE) Minimise sewage discharge to the natural environment Decentralized wastewater treatment system for reuse Minimize the use of hard engineerd structures Reduce pressure on infrastructure and flood risk by using water on a strategic scale 2 WATER-SENSITIVE DESIGNING (NEIGHBOURHOOD SCALE) -Green roofs Protect existing natural features and ecological processes Maintain the natural hydrological behaviour of catchments Integrate water to landscape to enhance visual, social, cultural and ecological values Allow surface runoff to infiltrate Rainwater harvesting: Rainwater collection from roofs in front raingarden Lengthening flow paths: Diverting the drainage flow to bigger areas and open swales Reduce/minimize imperviousness, preserve more trees and make permeable paving within residential streets -Buffer treatment zone for pollution abatement of water body WATER-SENSITIVE DESIGNING (INDIVIDUAL SCALE) 3° -Greywater reuse Green roofs: Reduces runoff from roof D Rainwater harvesting: Harvests runoff from roofs and provides stored water source on dry days for the gardening Reduce flooding at the downstream end of catchment area Raingarden Water efficient fixtures and appliances Adapted from: Morgan, C., Bavington, C., Levin, D., Robinson, P., Davis, P., Abbott, J. and Sinking, P., 2013.
