ITP Steel: Industrial Water Use and Its Energy Implications
Industry-wide, boiler use accounts for 22% of steel sector energy consumption and 3% of all industrial manufacturing energy consumed nationwide. Recent estimates have predicted a decline in the growth rate of steel industry process steam utilization from 1.7% to 0.3% per five year period (Jaber & Jones 1999, 2).

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.
