https://www.kwinana.wa.gov.au/our-city/news/Pages/City%E2%80%99s-Drainage-Nets-Post-Goes-Viral.aspxThe City of Kwinana's Facebook post on Saturday, 4 August 2018 about the success of its drainage nets installed in two locations in Henley Reserve, has gone viral with over 2.5 million people all over the world reached in 48 hours.
...
“The nets are placed on the outlet of two drainage pipes, which are located between residential areas and natural areas. This allows the nets to capture the gross pollutants carried by storm water from the local road network before those pollutants are discharged and contaminate the natural environment at the downstream end of the outlet area. This ensures that the habitat of the local wildlife is protected and minimizes the risk of wildlife being caught in the nets. To date no wildlife has been caught up in either of the City's nets."
"After seeing the nets in action in other local government areas, the City determined the net to be the most cost effective and safest option for wildlife over other methods such as underground gross pollutant traps which can be up to four times the cost per unit and are sealed and submerged structures," she said.
The nets cost the City just under $20,000 which included the cost of design, manufacture, installation and associated civil works for the two units and are expected to realise considerable cost savings in labour intensive work previously required to collect the rubbish scattered around the reserve by hand. This efficiency means the return on capital investment will be realised in the short term as well as cleaner reserves, higher efficiency and improved safety outcomes.
