 Water management in Dhaka faces numerous challenges such as flooding, poor service quality, groundwater depletion, inadequate sanitation, polluted river water, unplanned urban development, and the existence of large slums where more than one third of its population lives.Every year during the dry season, people demonstrate in Dhaka's streets demanding an uninterrupted supply of clean water.In 2010, Bangladesh's government had to even deploy troops to guard water pumps following angry protests.
