The Centre for Science and Environment (CSE) has prepared a background paper for the ministry of Urban Development on a rating system for water efficient fittings and fixtures in India. This is much-needed and will (like with the BEE ratings for energy efficiency) help architects who are interested in sustainable design in the choice of taps, showers and sanitary-ware.
The paper has some typos and errors but overall, the information is extremely useful -if a little technical. Free registration is required to download it from here.
