Dear Sir/Madam

Greetings for the day.....

Please find the below brief details of Water Project taken up by one NGO

"NGO set up Water Treatment plants and provide the treated water ( a process that may involve filtration, UV or ozone treatment, reverse osmosis that fit for human consumption ) for public consumption on nominal charge in water scarcity villages."

Doubt 1:
GST rate applied on Treated water provided in sealed container to public ?
Whether this Treatment can be called as Purification/Distillation ?

Doubt 2:
What is the GST rate applied when NGO provide treated water to public for consumption in villages, where the people bring their own vessels( such as can,tin,bottles etc..)?

Please provide your opinion, Thanks in Advance.
