Constructed wetlands can be found in many locations throughout Forster Tuncurry’s urban areas. They remove pollutants and sediments from stormwater runoff before it enters Wallis Lake.
Sediments in the estuary reduce the amount of light available for seagrass to grow, which is a natural habitat for aquatic life. Excess nutrients fuel algal blooms which also lead to habitat loss, impacting fish and aquatic bug populations," said Council’s Manager of Natural Systems Gerard Tuckerman.
The wetland helps prevent this by removing sediment and filtering nutrients from urban runoff prior to discharge into the Lake."
Constructed in 2001 and treating stormwater from 90 hectares of the surrounding suburban area, Townsend Street constructed wetland has reached the end of its expected functional life.
Constructed wetland feeding Wallis Lake from Forster Tuncurry.
Maintenance work involves removing built-up sediment, an upgrade to the bypass channel as well as structural works to replace the trash racks that filter out litter before it enters the wetland.
A major part of the project will also be the replanting of native wetland species which are very effective at removing nutrients and improving the quality of urban stormwater.
Work is expected to be completed by July. It is supported by the NSW Government’s Coast and Estuary Program and Council’s Stormwater Levy.
