About
Department of Mining and Energy awarded a contract to Ventia Australia Pty Ltd for water treatment and active management services at the Sandy Flat legacy mine site.
The contract supported remediation of Acid Metalliferous Drainage (AMD) over a 50-month period.
The scope included supply of reagent, supply and installation of HDPE pipes, treatment of water, and discharge of treated water to support remediation works, addressing approximately 500 ml of AMD-impacted water contained in the open pit.
The procurement used a multi-stage approach, beginning with an Expression of Interest to shortlist proponents for the subsequent tender.
Projects addressing legacy mine AMD remediation typically required contractors with combined capabilities in chemical dosing, HDPE piping installation and ongoing water-treatment operations, and procurement commonly used EOI shortlisting to verify specialised capability before tendering.
