Government  of  India,  in  partnership  with  States/  UTs,  is  implementing  Jal  Jeevan Mission(JJM)  -  Har  Ghar  Jal  to  provide  potable  tap  water  supply  to  every  rural household by 2024 with an estimated outlay of 3.60 lakh Crore. Under JJM, financial assistance is provided to States/ UTs. 'Water' being a state subject planning, approval and implementation of drinking water supply schemes, lies with state/UT governments.  While  planning  water  supply  schemes  to  provide  tap  water  supply  to households, priority is given to quality-affected habitations. States may decide appropriate water  treatment  technologies  for  treatment  of  water  to  provide  potable  water  to households.

For Jal Jeevan Mission, this Department has not sought any assistance from external agencies.  However,  for  technological  solutions,  a  Technical  Committee  under  the chairmanship of Principal Scientific Advisor (PSA) to Government of India has been set up to examine and recommend various innovations and water related technologies received  from  govt./  autonomous/  private  entities,  which  can  be  used  in  providing potable tap water supply to every household.
