Innovative Storm Water Management Water Sensitive Urban Design (WSUD)

Aspect of Water Sensitive Urban Design (WSUD)

i. Minimizing runoff at or near its source, by directing runoff from impervious surface to pervious areas to reduce quantity and improve quality of runoff

ii. Preserve the existing topography and features of the natural drainage system including waterways and water bodies.

iii. Integrate public open space with storm water drainage corridors to maximise public access, passive recreation activities and visual amenity, while preserving essential waterway habitats and wildlife movement corridors.

Water Sensitive Urban Design (WSUD)

iv. Preserve the natural water cycle including minimising changes to the natural frequency, duration, volume, velocity, and peak discharge of urban storm water runoff.

v. Protect surface water and groundwater quality.

vi. Minimise the capital and maintenance costs of storm water infrastructure

Low Impact Development Design (LID)

LID is modeled after nature i.e. manages rainfall runoff at the source using uniformly distributed decentralized micro-scale controls.

LID planning practices include site design planning based on natural land contours and decreasing the impervious surface. These methods include the following:

• Reducing impervious surfaces

• Disconnecting impervious areas

• Conserving natural resources

• Using cluster/consolidated development

• Using xeriscaping and water conservation practices
