Following our recent Williams Landing MOS project, Biofilta’s latest stormwater project is nearing completion in Doncaster, Melbourne. This is our largest above ground bioretention planter to date and the numbers are huge: 850m2 planter treating an urban catchment around 50ha in size.
Approximately 8,500 plants in 875m3 of our specialised layered filter media will cleanse the pollutants from over 300ML of storm flow per year. This workhorse system will remove 43,000kg of sediments, 73kg of Phosphorus and 341kg of Nitrogen from entering our sensitive waterways each year. It also waters itself in summer using some of the captured water in a 100kl underground tank. Pre-treatment upstream is essential and our underground GPT and sediment chambers protect the planter from clogging. Cleansed storm water will meet Best Practice environmental standards and filtered water will be reused for Council tree watering. We will post a detailed breakdown of this project in a few weeks.
