New Wetland To Help Clean Up Canning River

A $1 Million State Government-funded wetland designed to reduce nutrient pollution entering the Canning River was completed today at Anvil Way.
Environment Minister Bill Marmion said the project had turned a contaminated drainage basin in Welshpool, filled with heavy metals and hydrocarbons, into a living wetland.
The Swan River Trust’s Anvil Way Compensation Basin Living Steam Project remediated the contaminated basin, with the aim to improve water quality and reduce nutrients and other contaminants entering the Canning River.
“The basin is part of the Mills Street Main Drain catchment that has been identified as a key contributor of nutrients and contaminants going into the Canning River.” Mr. Marmion said.
“The project has created a meandering low-flow path wetland with hydraulic structures that will control water flow levels and stop sediment and other nutrients entering the river.”
“Contaminated sludge has been removed, treated and is currently drying in a lined storage area prior to disposal.” Mr. Marmion said.
“The native plants we put in today will revitalise the area and grow to provide a refuge for birds and other wildlife.”
“The finishing touches will be made in June, with the remainder of the project’s 48,000 plants going into the banks around the site.” Mr. Marmion said.
The Anvil Way Compensating Basin Living Stream Project is a partnership project between the Swan River Trust; City of Canning; South East Regional Centre for Urban Landcare; Public Transport Authority; Water Corporation; Department of Environment and Conservation; and Department of Water.
A large part of the State Government’s funding for the project was through the Swan Canning Water Quality Improvement Plan, which was allocated $3.19 Million in December 2009.
