US: Maximising water re-use

01.01.2015

When the US-based Indiana Harbor site’s water discharge permit came up for renewal last year it included new environmental conditions. This prompted the team to explore whether wastewater could be re-used rather than simply treated and discharged. The site is now one of the few steel plants in the US that has a wastewater system designed to achieve zero discharge. This water ends up as a clean steam discharge to the atmosphere. The water had previously been discharged into the Indiana Harbor ship canal and eventually to Lake Michigan.
