Water Sensitive Urban Design

Water Sensitive Urban Design • WSUD stands for Water Sensitive Urban Design • WSUD replaces earlier forms of stormwater management which focused on 'getting rid' of water more quickly by using concrete pipes.

• WSUD attempts to mimic nature by slowing the rate that water is dispersed.

• WSUD replaces impervious material with pervious materials where the rain lands.

• WSUD allows stormwater to be held in swales, gullys and dips to recharge ground water.

• WSUD filters and cleans water by natural filtration methods.

• WSUD provides water storage areas such as tanks ponds and wetlands for later re-use.

PUBLIC SPACES Open concrete drains like these speed up the rate of flow of water downstream and reduce absorption into the ground.

In heavily built up areas this water is conveyed under-ground in storm water pipes. They have the same effect. They also convey pollution – both visible and invisible- to the sea.
