As a company operating in a water-scarce region, Qatar Steel aims to reduce water consumption to the best of its ability, for the benefit of operations, as well as of the community and environment. Qatar Steel uses water in the form of freshwater, seawater, and recycled water in its operations, mainly as a cooling agent in addition of process
requirement.
Qatar Steel’s water management approach focuses on three objectives:
Decrease freshwater consumption
Reduce wastewater discharge
Increase the recycling rate of processed water

The reduction of freshwater consumption is due to the lower production rate of the plants. Discharge of used water (wastewater) has been an issue for industries which not only causes contamination to the environment, but it is also a resource and monetary loss for the industries. Near Zero liquid discharge (NZLD) is an engineering approach to water treatment where almost all water is recovered, and contaminants are reduced to solid waste. Qatar Steel is in the process of construction of a NZLD plant, with the equipment installation in progress as from 2nd quarter 2021.
