Since 2010, they have been planning on developing a unique water management system which will reduce reliance on portable water for irrigation, improve water quality and increase the wetland habitat.
By installing our SPEL Floating Treatment Wetlands, the project is a huge success and laid the foundation for the gardens to be 100% self-sufficient on water in near future.
How Does It Work?
- Stormwater is diverted from Anderson Street and Domain Road through gross pollutant traps to the wetlands at Nymphaea Lily Lake and Ornamental lake
- Specially designed floating island wetlands ‘clean’ the water as it flows through Guilfoyle’s Volcano reservoir and Ornamental Lake
- Water is pumped from the lake, filtered and then stored in four large water tanks. The stored water will then be treated with UV and circulated via underground pipes and pumps into the existing irrigation system to water the gardens.
The Benefits
- Reduced reliance on potable water for irrigation by up to 40 per cent
- Improved water quality in the lakes, reducing blue-green algal blooms in warmer months
- Increased wetland habitat for waterbirds, frogs and other aquatic fauna
- Reduced ‘dirty’ stormwater flows into the Yarra River and Port Philip Bay.
