We were chosen to create, establish and maintain the multi-award winning 160,000m² Etiwanda Wetlands, located in the South Eastern corner of Mildura, Victoria on Etiwanda Avenue. It is a fine example of how creating an artificial and functional wetland system can bring about multiple positive environmental benefits.
The wetland now captures close to 80% (700Ha) of Mildura’s storm-water and road runoff. Water from fruit blocks, paddocks, vineyards, residential land and industrial precincts finds its way into the multi-staged wetland system which cleans and stabilises the water before discharging into the Murray River. Additional benefits have also begun to emerge making these outstanding wetlands even more successful as time passes.
The popularity of the Etiwanda Wetlands is not measured by its ability to tame the storm-water of Mildura, but by the healthy environment and thriving ecosystem it has helped to establish.
Over 30 species of birds are either permanent or seasonal residents and vertebrates from surrounding vegetation have migrated here.
Processes included harvesting endemic seed and the germination of 50,000 plants and over 30 different aquatic and terrestrial species, the cleaning of grass, chenopod and legume seed prior to broadcasting over the terrestrial areas using our own purpose-built hydroseed truck.
Staff endured freezing temperatures, frozen water and plenty of mud while hand-planting the aquatic and terrestrial species. The site was handed over to Mildura Rural City Council 4 weeks ahead of schedule.
Our primary objective during the maintenance period was to manage aquatic weed species, focussing on creating a weed free environment for as long as possible. This type of work can only be successful when conducted by specialised staff with significant wetland training and experience and indigenous plant identification skills.
After almost 3 years of detailed and comprehensive construction and maintenance, enduring all seasonal conditions and challenges, Etiwanda Wetland was successful in winning the award for the Most Environmentally Sensitive Project in 2008.
