Treated Effluent Diversion Project

Treated Effluent Diversion Project

Bathurst Regional Council has been approached by LFB Resources, a wholly owned subsidiary of Regis Resources Ltd to supply treated effluent for use at their proposed open cut gold mine, the McPhillamys Gold Mine, at Kings Plains, near Blayney. Information on Regis’ Exploration Licence can be found on the NSW Department of Industry, Resources and Energy website

Regis Resources has requested a ten year contract with a ten year option from the commencement of the operational phase of their mine site, for the supply of treated effluent. Generally the water required for the mine is around 8 to 10 megalitres per day, which matches the annual average daily output from the Waste Water Treatment Plan. Regis at this stage do not have approval for the McPhillamy Gold Mine and would be required to enter into further regulatory processes if Council agrees to the sale of the treated effluent for use at the mine.

Council, at its meeting on Wednesday 18 November 2015, resolved to seek community feedback on the request from Regis Resources to purchase the treated effluent. This feedback will help inform Council’s final decision on the sale of treated effluent to Regis. Council considered the matter in February 2016.  The resolution appears further down this page.

A number of reports and studies have been completed to help inform Council’s position, to date.

BRC commissioned Sinclair Knight Merz to complete a report on the Environmental Impact of Diverting Bathurst Effluent Water to McPhillamys”, May 2014 - SKM Report   This report was then peer reviewed by GHD Bathurst Waste Water Works Diversion of Treated Effluent EIA Review September 2014

NSW Public Works has prepared a report, NSW Public Works Report, Bathurst Sewage Treatment Plant Effluent Reuse Study looking at the Regis proposal, how it would be progressed, infrastructure requirements and implications for ongoing operation of the Waste Water Treatment Plant.

A copy of Council’s Environment Protection Licence for the operation of the Bathurst Sewage Treatment System can be found here  Environment Protection Licence for the operation of the Bathurst Sewage Treatment Plant
