Sir: Water is the basic need of life. Human beings need to drink at least eight glasses of water to remain hydrated throughout the day. At homes and workplaces, drinkable water is easily available but there are no public water dispensers in Karachi. The heat and humidity of Karachi make people (especially travelling on foot) experience this problem and they have to purchase water bottles. Most of the time people became dehydrated and face its aftermath. It is the responsibility of the government and concerned authorities to provide clean drinking water to citizens. I would request the concerned authorities to look into this matter and come forth with a solution to this problem. FARJAD SHAKEEL Karachi
