Installation of Drainage Nets
The City of Kwinana installed two drainage nets at the piped drainage outlets located in Henley Nature Reserve, Leda, in March 2018. The City also installed another three drainage nets during the 2019/20 financial year at the drainage outlets located at Orelia Oval (Lot 501 Christmas Avenue), Sloans Reserve and Lot 766 Oakley Road.
The drainage nets were installed at the outlets of concrete drainage pipes (450mm and 750mm diameter) to prevent pollution of the nature reserve by intercepting and collecting solid waste conveyed by the piped drainage system. The solid waste entering the piped drainage system from various residential road reservations mainly consisted of food wrapping, drink bottles, cans, organic waste including tree leaves and other domestic waste generally found in urban road network.
The drainage nets were designed and supplied by Urban Asset Solutions and installed by the City of Kwinana. The supply and installation cost of the drainage nets were approximately $10,000 each. This also included the cost of civil upgrade works, ie improvement of access to the drainage nets.
