Manly Council Stormwater Treatment and Reuse Project

Sydney, New South Wales

Environmental Issues

Manly is a fully developed (ultra-urban) suburb with high concentrations of residents and visitors. Impervious surfaces concentrate rainfall into stormwater that is polluted with nutrients, hydrocarbons, heavy metals, toxicants and litter. Drains discharge directly to Ocean Beach, polluting the waters and restricting swimming for up to three days after heavy rain.

Water Quality Management

External and internal screens will be fitted to existing stormwater drains. These will prevent litter and sediments from entering drains, and oils, fine sediments and grease from exiting drains. Porous pavement will replace existing road surfaces, and a newly established carpark will incorporate Atlantis paving that will treat, store and reuse stormwater runoff for irrigation on to Norfolk Island Pines along the foreshore.

Resources 2000/2001 - 2001/2002

Urban Stormwater Initiative $ 545,639
Other Contributions $ 770,000
Total Project Costs $1,315,639

Longer Term Benefits

The project aims to improve the quality of water entering Ocean Beach by using a sub-catchment 'treatment train'. Public education campaigns will support pollution control infrastructure, and will emphasise the role of individuals in disposing of litter appropriately. The project will promote best practice in a very high profile location, and will be an example for other 'ultra-urbanised' areas.
