Derwent Valley Council Turriff Lodge STP Outfall Relocation Project

What's this project all about?

The Turriff Lodge Sewage Treatment Plant (STP) treats sewage from New Norfolk. As part of TasWater’s commitment to upgrade existing water and sewerage infrastructure across Tasmania, the Turriff Lodge STP anaerobic digester and outfall configuration are being modified.

At present, treated water from the STP flows through the adjacent man-made wetlands, before entering the Derwent River Estuary. The wetlands is a constructed area that is now beyond its service life, and as part of this project will be decommissioned and turned into a grassed open area. So treated water from the STP’s upgraded digester process will bypass the wetland via a newly built outfall.

An environmental study of the wetlands has determined that no undue impact will be caused to local flora and fauna as a result of this plan.

TasWater understands the importance of the foreshore for locals and visitors, and is working with Derwent Valley Council, Environment Protection Authority and Tasmania Parks and Wildlife Service to help ensure a positive outcome.
