Best Learning WSUD

Water Sensitive Urban Design is based on the integration of the two key fields of ‘integrated urban water cycle planning and management’ and ‘urban design’ (Wong and Brown, 2009)

• Water management • Placemaking

Sustainable Drainage System (SuDS) can be a key part of WSUD to integrate surface water runoff management into the urban form, but WSUD brings in broader consideration of the whole water cycle

SUDS techniques

• Water butts• Sub-pavement storage• Swales• Tank Sewer Storage• Roof Storage (flat)• Infiltration Basin• Paved Surface Flooding• Detention Basin

SUDS techniques

• Retention Pond• Permeable Pavement• Soakaways• Infiltration Trench• Filter Strip• Wetlands
