The water and environmental sanitation sector has been one of the most vital sectors supported by King Salman Humanitarian Aid and Relief Center (KSrelief) in the countries in need, especially Yemen. Within the efforts of the KSrelief in the water and environmental sanitation sector in Yemen, it has implemented 32 projects aimed at pumping and preserving water, providing sustainable solutions for the environment, distributing drinking and non-drinking water, and reducing the spread of the diseases and epidemics in various governorates of Yemen. These efforts come within the framework of the humanitarian and relief projects being provided by the Kingdom of Saudi Arabia, represented by the KSrelief, to the Yemeni people to improve their living conditions during the current humanitarian crisis.
