Sir: Nowadays, Karachi is facing acute water shortage in many areas because of poor planning of Sindh government. People are forced to consume unhygienic water. Unavailability of pure drinking water result in increment of it price at very high level. Regular usage of unhygienic water is injurious to the health of the citizens. Sometimes sewer-mixed water is supplied by water mafia. Through the medium of your esteemed newspaper I would like to draw attention of concerned authorities to solve this issue.
