I am planning to start a business of water plant i.e. purifying and supplying of water is halal or haram in Islam or it is permissible in Islam.
بسم الله الرحمن الرحيم
(Fatwa: 1664/1214/H=11/1434)
It is halal. You should maintain balance in the price, it is better. It is not better to take more price than usual.
Allah knows Best!
