Why in news?
- The Union Environment Ministry has published a draft notification that effectively prohibits users from installing MWPS [Membrane-based Water Purification System], mainly reverse osmosis, in their homes if the water has been sourced from a supply that meets the BIS drinking water norms.
About:
- Installation or use of MWPS shall be prohibited, at the point of use or at the point of entry for purification of supplied water which is subjected to conventional flocculation, filtration and disinfection process or is from any sources which are in compliance with acceptable limit for drinking water prescribed by Bureau of Indian Standard 10500:2012.
- The proposed regulation is not the final word and the Ministry will await comments from the public for 30 days, after which it may incorporate the changes before it becomes a law.
