People used to drink tap water all over the country in the past, but now tap water is dangerous and everyone has to buy water, whether they can afford it or not in Karachi and other cities of Pakistan. The tap water has fungi which is harmful and smelly. It is time that people of Karachi were able to drink water from taps. I request the authorities to provide drinking water to this large city inhabited by millions.
