Tailings dredging

Water & tailings management

While Hall Contracting is widely recognised for its dredging, pumping, and civil construction capabilities, our team also provides a diverse range of water and tailings management services to the mining and heavy industrial sectors.

Hall Water & Tailings is Hall’s dedicated division providing tailings dam remediation, dewatering, slurry and water management, and water infrastructure services.

We are proud to have successfully carried out projects on behalf of many mining and resources companies throughout our 75 years of operation, including Rio Tinto, Glencore, Fortescue, BHP, and Energy Resources of Australia.

Hall is well placed to service mine and industrial sites across Australia, South-East Asia and the Pacific Islands, with our extensive fleet of amphibious and cutter suction dredges well-suited to mining applications.

Hall’s capabilities in this area include:

Tailings, production water & environmental dam dredging

We assist mining companies to manage a range of materials, control the capacity of tailings storage facilities and capture valuable commodities left over in waste products.

Hydromining

Using large dams and gravity-fed ponds designed to capture tailings deposits over time, Hall is capable of using hydromining cannons to hydraulically blast material to maintain storage capacity. We also employ hydromining technology to convert waste material to slurry.

Operation and maintenance

Our team can successfully operate and maintain client-owned assets including dredges, pipelines and booster pumps, as well as water pumping infrastructure used for bulk water transfer.

Custom solutions

We recognise every project is different, which is why we work collaboratively with clients to develop customised solutions to short- and long-term water and tailings asset challenges.

Pumping solutions

We have extensive experience in all aspects of dewatering and water transfer. Hall can tailor cost-effective water management solutions to meet the individual needs of clients, while achieving regulatory compliance. We undertake:

Dewatering

Hall owns and operates a range of pumps that can be utilised to dewater dams and mine pits, creating dry, workable conditions. The pumped water can be utilised in wash plants or for other operational purposes such as dust suppression.

Emergency dewatering

When sites are negatively impacted by rain and flooding, Hall can assist with extracting floodwater, enabling mining operations to resume promptly and safety. We mobilise quickly in emergency situations and support mine sites during potentially catastrophic events.

Waste/process water transfer

We have the equipment to shift large volumes of water, making it available when and where it is needed. For sites with a water surplus, we can safely discharge off-site in line with licensing conditions, and have the capabilities to comfortably manage contaminated water.

Slurry pumping

Using our extensive range of dredges, booster stations and pipelines, our team has the capability to pump dredged material more than 10km for storage or reprocessing.
