Saving water, saving costs: water recycling in India
Case study 06 AUG 2018
Water is essential to our business – and to the people and ecosystems around us. That means responsible water stewardship is a strategic priority – especially in areas of water stress, where factors such as drought and climate change have their greatest impact.
In India, an acutely water-stressed region, we’ve developed a comprehensive local strategy to conserve water. This supports our global targets for 2020 of reducing the amount of water we use, returning wastewater safely to the environment and replenishing the total water used in our final product.
A recent programme of investments in our distilleries in Maharashtra state has driven further improvements. We have installed new water-recycling equipment, including ultra-filtration followed by reverse osmosis systems at our Nasik, Aurangabad and Pioneer sites. This has enabled us to re-use up to 500,000 cubic metres of water a year – enough to fill 200 Olympic swimming pools.
This water reuse has led to a 35% reduction in water extraction, which is good for the long-term sustainability of our business and the local water catchment and community. It has also had immediate fiscal benefits, by saving more than £1 million in costs resulting from a new state water tariff.
