The Wastewater Treatment and Reuse Plant at Taronga Zoo was opened in 1996 as part of an original 'Clean Up Australia' initiative. The primary aim of the Plant is to keep Sydney Harbour clean and healthy while also minimising the volume of fresh water needed for the many activities that are undertaken on a daily basis at the Zoo.
The treatment and reuse plant is currently undergoing major upgrade works including a new stormwater tank, a new micro-filtration unit and process enhancements. Once the upgrade is complete, the system will reclaim up to 100 million litres annually. This project is supported by the NSW Government's Water Savings Fund, which is now part of the NSW Climate Change Fund.

Taronga Zoo is part of Sydney Water's ‘Every Drop Counts' Business Program. Taronga works with Sydney Water to identify water savings opportunities on-site with the aim of reducing fresh water consumption. The program has been a great success to date and the zoo continually seeks ways to minimise the use of fresh water and optimise the use of recycled water as part of its commitment to sustainable resource use.
