Bronte Gully Stormwater Harvesting and Re-use

Way back in the 1870s, local historian Major W.L Johnstone noted that Bronte Creek had a continual flow. The 135 hectare Bronte catchment has changed a lot over the years, but Bronte Creek has continued a healthy flow.

Climate change requires that we think, act and adapt in a sustainable way. One impact of climate change is changing rainfall patterns and water shortages.

The innovative Bronte Gully Stormwater Harvesting System was undertaken as part of Waverley Council’s ongoing commitment to sustainable water management. The system has been designed to utilise the reliable stormwater flow travelling down the channel that would otherwise go straight out to sea. It is estimated that this initiative saves in excess of 12 million litres of water a year.

key benefits of the system include:

  • Large amouts of water saved every year
  • Improved park aesthetics, amenity and recreational value due to adequate watering even during water restrictions
  • Reduced stormwater flowing into Bronte Beach, reducing risk of pollution
  • Open space maintained - as the system is underground


Harvested and treated water is:

  • Used for cleaning Bronte Pool and other public spaces.
  • 120 Kiloliter underground storage tank - roughly the size of an average household swimming pool
  • The primary supply of water to both amenity blocks (toilet and urinal only).
  • The sole source of water for park irrigation and bush care activities.
