İstanbuli (Istanbul) Water Supply

Istanbul’s water supply comes mainly from the nearby Sakarya River and nearby lakes, which are managed through extensive dams and reservoirs. Water is collected, treated at water treatment plants to ensure purity, and then distributed through a network of underground pipes and pumping stations to millions of residents. The system is designed to meet high demand due to the city’s large population, and efforts are ongoing to improve water quality, reduce losses, and ensure sustainable use by protecting water sources and upgrading infrastructure. This integrated approach ensures a reliable supply of clean water to Istanbul’s households and businesses.
