SEWAGE TREATMENT FOR MINING INFRASTRUCTURE AREA

BACKGROUND

One of the large global mining and processing companies was developing a new mine to extend the life of their Weipa bauxite operations by a planned four decades.

MAK Water was engaged by the global Engineering, Construction, and Project Management Company (EPCM) contractor to design and construct the sewage treatment plant for the mine infrastructure area (MIA). 

The plant was constructed according to project engineering and design specifications, using project preferred electrical equipment, and supplied with site specific vendor drawing and data package. MAK Water provided site installation support and commissioning of the plant.
