GWM Water applies for EPA Works Approval

Environment Protection Authority Victoria (EPA) is assessing a Works Approval (WA) application from Grampians Wimmera Mallee Water (GWMW) 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 (WWTP) on Kiely Street around 380 m north of the closest house in the township.

The WWTP is proposed to consist of two lagoons and an onsite tree lot which would be irrigated by the treated Class C water. It is proposed there will be no onsite discharges to groundwater.

EPA will assess the application for potential environmental impacts, such as noise, odour, air emissions and potential land, surface water and ground water contamination risks.

Submissions on the application are open until 10 March 2021.

What is a Works Approval?

Works Approvals are issued by EPA under the Environment Protection Act 1970. They are required for industrial and waste management activities that have the potential for significant environmental impact.

A Works Approval permits plant and equipment to be installed, the operation of which will result in one or more of:

• the discharge of waste to the environment

• an increase in, or alteration to, an existing discharge

• a change in the way waste is treated or stored.
