A 2021 study by TERI and Delhi University found that nearly half of the city's 5.5 lakh households use RO water purifiers. About 6 MLD of drinking water is produced daily using RO machines. Since, for every one litre of RO water, nearly three litres are wasted. As a result, around 12 MLD of water is wasted every day. RS Sinha said since one person drinks about 2.9 to 3.5 litres of water, this wasted water alone could meet the daily drinking water needs of 33–40 lakh people.
