Tap water in Pakistan is not recommended for drinking; bottled or properly filtered water is safer.
Urban water supply
In cities such as Islamabad, Lahore, and Karachi, tap water is treated but may still contain contaminants unfamiliar to visitors.
Rural areas
In smaller towns and rural areas, water quality can vary significantly.
Health precautions
Using sealed bottled water for drinking and brushing teeth reduces the risk of stomach illness.
