How to manage daily drinking water

You can buy water purifiers which is available with options (hot water, cold water and normal water). It will be connected through a water pipe. Thanks

I believe a simple Google search could show various drinking water suppliers (bottled or otherwise) and also filter and purifier companies.
But why would anyone go to such extent when in a place with excellent water from the tap for almost free?!?

Thanks for the replies, yes I did search for few water can suppliers but they are over pricey. I am new to the place and with my kid and would want to know on moderately priced water can suppliers as I am used to hot/cold dispenser and heavily reply on hot water for general consumption
