Improving water quality

What is stormwater?

When it rains, the water that runs off roads, driveways and roofs is known as 'stormwater'. Rubbish and pollution from your street will be carried by the stormwater along gutters and drains, to local creeks and rivers, and into the bay.

What do we do to improve water quality?

We clean our streets regularly, install pollutant traps, and more recently, through incorporating Water Sensitive Urban Design practices in our City.

What is Water Sensitive Urban Design (WSUD)?

Water sensitive urban design focuses on the temporary storage of stormwater, at or near its origin, to slow and filter its passage. Instead of going straight to our waterways, stormwater is treated and often used for other purposes such as irrigation. The benefits include improved landscapes and water quality, as well as reduced tap water use.

Examples of WSUD include: raingardens, bio-retention swales, wetlands and rainwater tanks.

Raingardens

A raingarden works like a filter stopping rubbish and other street pollutants from entering our waterways.

Read the Raingardens flyer (pdf, 235KB) for more details.

Wetlands

Wetlands also protect waterways by filtering pollutants through a series of shallow ponds with aquatic plants.

Read the Wetlands flyer (pdf, 400KB) for more details or take a self guided walk around the Afton Street Conservation Park wetland (pdf, 1.8MB).
