Operation and maintenance of Water Sensitive Urban Design (WSUD) and stormwater harvesting assets pose significant challenges within the industry. Despite the existence of excellent solutions developed over the years, many of these advancements have not been put into practice.
In an attempt to address these issues and promote the adoption of best practices in the operation and maintenance of WSUD and stormwater harvesting, IPWEA VIC organized a workshop on June 3rd, 2014, at Banyule City Council. The workshop aimed to provide a platform for knowledge sharing and discussions on these topics, facilitating the exchange of ideas and solutions.
For the past seven years, IV Water has been supporting the management of plant maintenance by undertaking engineering tasks related to the operation of AAMI stadium rainwater harvesting facility and Melbourne Park stormwater harvesting facility. They have conducted comprehensive assessments of the asset conditions, reviewed performance, and provided recommendations for modifications required at the Water Treatment Plant (WTP). These proposed modifications and upgrades have been implemented accordingly.
Melbourne & Olympic Parks currently operates the Stormwater Harvesting facilities with technical support and guidance from IV Water. As part of the ongoing maintenance efforts, regular clean-outs of the external infrastructure are conducted to ensure proper operational functioning. This includes the cleaning and inspection of stormwater diversion structures, detention tanks, pump stations, and Gross Pollutant Traps (GPTs). Through these activities, approximately 25.0 tons of pollution and sediment are intercepted, captured, and diverted from entering the Yarra River during each clean-out cycle.
IV Water established successful collaboration between Melbourne & Olympic Parks and City West Water. A transfer pipeline was completed in June 2019. This pipeline connects the Western Courts scheme to Melbourne Park, resulting in an additional 12,000,000 litres of runoff water being integrated into the Melbourne Park stormwater harvesting scheme resulting in combined total of 52,000,000 litres per year.
