YEAR OF CONSTRUCTION:
Newmont initiated a study in 2016 and concluded that the construction of the D6 Water Storage Dam with a minimum of 6GL storage capacity was required to assist with the expansion of the southern waste dumps at the Boddington mine site.
The dam will provide long term water security and will mitigate the risk of running out of water. The water will be pumped into the D6 Dam from the Hotham River Pump Station No 1 and No 2.
Ertech began the project at the start of 2020 with works due to be completed in 2021. The scope of works includes:
- Construct D6 Dam including embankment, inlet channel, seepage sump and spillway;
- Install D6 Dam including embankment liner, outlet pipework (including concrete pipe supports and pipe surround), inlet channel geofabric, seepage drainage (including finger and collector drains), seepage sump (including outlet pipework and liner), spillway liner and instrument works;
- Construct Junglen Gully Diversion (including embankment);
Install Junglen Gully Diversion (including pipework and storage tank/dam).
