Growing population, industrialization, agricultural practices and urbanization have increased the water demand and hence the quantity of wastewater (ww). Availability of drinking water, including different components of daily per capita demand in developing countries, is becoming a serious issue to manage. To fight with growing water stress, reclamation and reuse of treated ww for various day-to-day uses except for drinking purpose is necessary. Reuse of ww in Indian cities, not a substantial but a small fraction, may bridge the gap between supply and demand of water in the future. This also deals with a viable technological option for reuse of ww.
