Hello,
I am residing in Salem, Tamil Nadu. I want to harvest rainwater. I have a big underground sump tank to store water with a capacity of 12000 litres approximately. I can connect all the pipelines to the sump from first and second floors of my building to collect rainwater.
I would like to use this collected water for washing, bath and for cooking and drinking purposes. Please suggest appropriate purification system that I will have to use. Also please share contact details of people who can help set this up for me in Salem.
Thanks and regards,
