Bronte Gully stormwater saved

Waverley Council will save more than 73 million litres of water each year once an innovative harvesting system is built at Bronte Gully.

Waverley Mayor Ingrid Strewe welcomed the installation of a 120,000-litre tank to capture the continuous flow in the stream.

‘At the moment large amounts of stormwater flow down the gully and out to sea,’ she said.

‘Heavy rain can force the stormwater down at high speeds eroding the banks as well. Currently this water simply flows out to sea and we were sure we could capture it and use it to keep our park and gully beautiful.’

The stormwater will be used to irrigate popular Bronte Park, in the public toilets, and for the use of Bronte Gully Bushcare. If there’s enough water, some will be pumped up to the Bronte House gardens.

‘The stormwater will be captured in an underground tank and then pass through a UV treatment system to kill any pathogens. The water will be purified before we use it,’ the mayor said.

‘This is something Council has wanted for a long time, so it’s great it’s now one step closer with construction starting this week.’

Prime Water Technologies has been contracted to carry out the works, with the system due to start operating in September.
