Dubai, United Arab Emirates

Sanitation issues
Currently, human waste is collected daily from thousands of septic tanks across the city and driven by tankers to the city's only sewage treatment plant at Al-Awir. Dubai's rapid growth means that it is stretching its limited sewage treatment infrastructure to its limits. Because of the long queues and delays, some tanker drivers resort to illegally dumping the effluent into storm drains or behind dunes in the desert. Sewage dumped into storm drains flows directly into the Persian Gulf, near to the city's prime swimming beaches. Doctors have warned that tourists using the beaches run the risk of contracting serious illnesses like typhoid and hepatitis. Dubai municipality says that it is committed to catching the culprits and has imposed fines of up to $25,000 and threatened to confiscate tankers if dumping persists. The municipality maintains that test results show samples of the water are "within the standard".
