The Ministry of Environment, Water and Agriculture (MEWA) governs the Kingdom’s water sector. It is responsible for water policies and regulations. It also provides water and wastewater services across 13 regional directorates. The regulation of seawater desalination assets is covered by the Electricity and Co-generation Regulatory Authority (ECRA), which sets key performance indicators for desalination and encourages private sector involvement. In addition, ECRA is responsible for co-generation. SWCC - Saline Water Conversion Corporation - is the branch of the government responsible for the desalination of seawater, and possesses the largest desalination capacity in the world. A number of IWPP (Independent Water and Power Producers) also contribute to desalination in the Kingdom. The Water and Electricity Company (WEC), equally owned by SWCC and the Saudi Electric Company, is the off-taker for IWPPs’ production. The National Water Company (NWC) is responsible for groundwater extraction and treatment and for water distribution and wastewater collection and treatment in Riyadh, Jeddah, Mecca and Taif. NWC is also responsible for Treated Sewage Effluent (TSE) commercialization across the Kingdom.
