Tata Steel is committed to play a leading role in conservation of water and significantly reduce its impact on water. The steel company, which has setup a 30,000 cubic meters a day (m3/d) tertiary-level treatment plant in 2018, has now resulted in a 16 per cent cut in the intake of fresh water from the Subarnarekha River. The award-winning tertiary-level treatment plant was built to reclaim effluent from the Bara wastewater treatment plant in Jamshedpur for reuse by Tata Steel. The plant, implemented by Tata Steel’s civil utility wing JUSCO (Jamshedpur Utilities and Services Company), will benefit Tata Steel and the adjoining industries in Jamshedpur.
According to Sanjiv Paul, Vice President, Safety, Health & Sustainability, Tata Steel, the success of the Bara project is a great example of how industrial units and civic utilities can work together for the greater good that ensures long-term sustainability of all the stakeholders.
The Ultra-Filtration treatment plant is part of Tata Steel’s ambition to make Jamshedpur the first zero liquid discharge city in India. Since the completion of the facility, the entire city’s collected sewage effluent, from both domestic and industrial sources, is gathered and reused by the city’s extensive industrial complex. To improve city’s rate of collection of untreated industrial and domestic waste, JUSCO laid a 500-km sewer pipeline and built ten automated sewage pumping stations and control centres, thus transforming the sewerage service coverage for the city.
The Jamshedpur plant has doubled its annual capacity over the last 10 years from 5 MnT to 10 MnT (million tons). Tata Steel is committed to reduce its freshwater consumption by 50%.
