Wassa
A gold mining operation in Ghana’s Western Region, supplied with treated water through a dedicated pipeline branch.
Illegal mining loads the Ankobra with clay and silt. We abstract that water, treat it to industrial specification, and supply it reliably to three mines — Wassa, Edikan and Chirano.
Illegal mining — galamsey — washes heavy loads of clay and sediment into the Ankobra, leaving the river too turbid to use directly.
Mines in the Western Region need large, dependable volumes of water to operate. Drawing it straight from a clay-choked river is not an option, and groundwater alone cannot meet demand through the dry season. We close that gap.
From a turbid river to industrial-grade supply, in five stages.
Raw water is drawn from the Ankobra River through a screened intake and pumped to the treatment works.
Settling trenches and storage ponds drop out the heavy clay and silt that illegal mining washes into the river.
Aluminium sulphate dosing binds the fine suspended solids so they can be removed, clarifying the water.
Sodium hypochlorite dosing and filtration bring the water to the quality our industrial customers require.
Treated water is delivered through a dedicated pipeline network to each mine, monitored and controlled by SCADA.
One abstraction and treatment system, serving three mining operations through a shared pipeline network.
A gold mining operation in Ghana’s Western Region, supplied with treated water through a dedicated pipeline branch.
A gold mining operation in the Western Region, served by the same abstraction and treatment system via its own pipeline.

Treated water is delivered from a dedicated treatment plant and storage pond to the mine, with raw water drawn from the adjacent Suraw Pond and stream.
We co-invest with our customers and supply on an open-book, value-for-money basis.
