Reducing mine water requirements
To reduce water lost due to human consumption, the mine has redirected all available waste water, or grey water, after treatment, directly to the process water tank. Gleick (1996) recommends a basic water requirement of 50 l/p/d, based on 5 l/p/d for water consumption, 20 l/p/d for sanitation, 15 l/p/d for bathing and 10 l/p/d for food preparation.
