Isabella Plains rain garden.
05 July 2019
Did you know the Isabella Plains rain garden is the biggest in the southern hemisphere?
The garden is located in the parkland beside Upper Stranger Pond and has a treatment area of 5,200m2.
Construction of the rain garden started back in 2017 as part of the ACT Healthy Waterways project, with a focus on limiting the amount of pollutants entering the Lake Tuggeranong Catchment.
Stormwater runoff is a major source of water pollution in our creeks and lakes, and threatens the quality of life for aquatic animals living in our waterways.
Since construction began in the Isabella Plains rain garden, over 35,000 seedlings have been planted in the region and it is now home to numerous native birds and wildlife.
The rain garden will treat 1800 litres of storm water a second before it enters the lake and remove 80,000kgs pollutants every year, including nitrogen, phosphorous and suspended sediment.
