New sewerage scheme mooted for Wimmera town

Grampians Wimmera Mallee Water is seeking approval to construct a wastewater treatment plant.

Environment Protection Authority Victoria (EPA) is assessing a works approval application from Grampians Wimmera Mallee Water (GWMWater) seeking to construct a wastewater treatment plant.

GWMWater is developing a new sewerage scheme in Kiely Street, Goroke, in Western Victoria to manage ongoing issues with the current residential septic tank and drain field system.

GWMWater proposes to construct a septic tank effluent discharge system reticulation and a new wastewater treatment plant on Kiely Street around 380 metres north of the closest house in the township.

The plant will consist of two lagoons and an onsite tree lot which would be irrigated by the treated Class C water. Under the proposal, there will be no onsite discharges to groundwater.

Submissions on the application are open until 10 March 2021, after which the EPA will assess the application for potential environmental impacts, such as noise, odour, air emissions and potential land, surface water and groundwater contamination risks.

It has been a busy six months for GWMWater. The utility recently turned the tap on to fill the newly constructed Yaapeet Lake in the Wimmera region of western Victoria. It had been redundant since the completion of the Wimmera Mallee Pipeline but, now filling with water, will become a vibrant space for wildlife, locals and visitors to enjoy.

In 2020, GWMWater also completed the South West Loddon Pipeline, which provides a secure reticulated water supply to 1500 rural properties in areas surrounding Inglewood, Newbridge, St Arnaud and Wedderburn.
