EPA considers proposal for relocation of discharge from Geeveston WWTP to the Huon River at Shipwrights Point

​​The Environment Protection Authority (EPA) has concluded its assessment of a proposal by the Tasmanian Water and Sewerage Corporation Pty Ltd (TasWater) for the relocation of Geeveston Wastewater Treatment Plant (WWTP) outfall to the Huon River at Shipwrights Point in the Huon Valley.

The proposal is to relocate the existing outfall (discharge) of the Geeveston WWTP from its current location in the Kermandie River to Shipwrights Point on the Huon River. The proposal includes construction and operation of a new treated effluent pumping station at the Geeveston WWTP, a new 4.3 km pipeline, and an outfall pipe with diffuser to a water depth of 8m.

​The EPA Deputy Director, Cindy Ong, who made the determination under delegation from the EPA Board, concluded the proposed development can be managed in an environmentally sustainable and acceptable manner, with certain conditions. The Board requires these conditions to be included in any permit subsequently granted by the Huon Valley Council.

“Various environmental issues were considered in the assessment, particularly the impact of the relocated discharge on water quality in the Huon River. The new Shipwrights Point discharge location is into a significantly larger waterbody than currently occurs. The outfall pipe will also be fitted with a diffuser to assist with dilution and dispersion of the effluent. This will offer immediate benefits in terms of reducing eutrophication impacts to the Kermandie River. Environmental conditions imposed require a program of receiving environment studies following commissioning of the new outfall to validate modelling of the discharge, understand the impact of the new discharge regime and identify any further improvements that may be needed," Cindy Ong said.

Public consultation was open for 28 days from 10 September 2021and no representations were received.

The proposal was considered by the Deputy Director in the context of the sustainable development objectives of the Resource Management and Planning System of Tasmania (RMPS) and the objectives of the Environmental Management and Pollution Control System (EMPCS) established by the EMPC Act.

The functions of the EPA are to administer and enforce the provisions of the EMPC Act, to further the RMPS and EMPCS objectives and, in particular, to use its best endeavours to protect the environment of Tasmania.

The Deputy Director undertook the assessment of the proposal in accordance with the Environmental Impact Assessment Principles defined in Section 74 of the Act.

The Deputy Director's environmental assessment report, including the environmental conditions, has been issued to TasWater and Huon Valley Council for their information.
