The City of Kwinana, south of Perth, has generated international interest for its drain socks.
In March 2018, nets were fitted to the mouths of two local stormwater drains to trap litter and debris that washed into the system after a rain storm. They have a team that comes in to clean the drains and they pick the sock up, dry the trash, sort it, and then mulch it.
Kelly: I’ve always thought that sieving and then treating water with UV light to destroy pathogens makes a great deal of sense, especially for water that will end up back in the sea or lakes. This is such a low-tech clever idea I hope it gets picked up all across the world. Even reducing plastic waste makes it worth it.
