Hallaton introduces MEGA-Drain

News | January 1, 2024 | By:

Hallaton Environmental Linings has announced the launch of MEGA-Drain – Moisture Eliminating Gravity Apparatus. Bringing 30 years of geosynthetic installation experience, the company has partnered with MEGA-Drain Corporation to offer their press-less, dry-stack tailings and water management system.

MEGA-Drain is the first “smart” drainage solution optimally engineered to dry stockpiled ore, recover decant, hold and treat decant, and allow for dry-stacked tailings management without mechanical filter presses. Its multi-layered design leverages airflow, negative air pressure, and gravity to enable passive drainage, storing water underground in a non-reactive vault.

With reduced costs, complexity, waste, and footprint requirements compared to traditional decanting methods, Hallaton believes the MEGA-Drain system will be the mining industry’s “best practice,” and is honored to play a role in the future of responsible mining material processing, and stockpiling.


Tailings stream of underflow/overflow from cyclone discharge – recover water at the end stage of processing

Production stockpiles from radial stackers/cyclones/trippers/tunnels and reclaimers

Water storage–lined impoundments with floating covers lasting 30 years

The MEGA-Drain system is scalable, modular, simply installed, and rapidly constructed. It reduces a project’s total requirements for water, does not require filter presses or the facilities to house them, and removes more moisture faster than filter-press-based solutions.


Reduce stockpiled material moisture contents sub 5% to low single digits rapidly.

Eliminate material rehandling.

Reduce fuel consumption and carbon footprint.

Reduce plant upset conditions with consistent low moisture feed stock.

Reduce OPEX with discernable and accurate CAPEX for asset.

Increase production 20 -35%.

Increase EBITDA with measurable ROI.

Increase plant/production options by increasing water reserves.

Increase market capitalization.
