Indian Water Management Outlook

According to World Bank, Indian Water sector industry is worth around USD1bn and is expected to grow 40-50% in next few years. By 2020 the demand of water in India will exceed the available sources of fresh water; Creative solutions are required such as reuse/recycle & efficient use to tackle this issue. The industrial use of water is predicted to increase from 30 to 120bn cum in 2025.
