A bench of Chief Justice G Rohini and Justice Jayant Nath issued notice to the ministries of Health and Consumer Affairs seeking their replies within four weeks and listed the matter for further hearing on September 16.
"Get instructions. It is an important issue which needs consideration. Notice. File your counter in four weeks," the court directed the ministries.
The PIL has alleged that there are about 10,000 illegal bottled water units operating in the National Capital Region (NCR) itself which sell around 30,000-40,000 bottles daily "by refilling used bottles and illegally using labels of 64 licensed and branded manufacturers".
"It must be borne in mind that it is primarily these regular sources of water which is used for refilling counterfeit bottled water. Up to 40 per cent of bottled water comes from the same source as tap water," it has said.
It has also said that despite a 2009 order of the high court directing the authorities to take immediate strict action against manufacturers of bottled water operating without obtaining licences, "the problem of spurious water bottling still persists, and on account of this worrying concern the PMO recently in the month of June 2015 has asked states to check water bottling racket".
