''This article was last comprehensively updated in March 2009, with some updates in April 2014.'' Tunisia has achieved the highest access rates to water supply and sanitation services among the Middle East and North Africa. As of 2011, access to safe drinking water became close to universal approaching 100% in urban areas and 90% in rural areas.〔 Tunisia provides good quality drinking water throughout the year.〔 Responsibility for the water supply systems in urban areas and large rural centres is assigned to the ''Sociéte Nationale d'Exploitation et de Distribution des Eaux'' (SONEDE), a national water supply authority that is an autonomous public entity under the Ministry of Agriculture. Planning, design and supervision of small and medium water supplies in the remaining rural areas are the responsibility of the ''Direction Générale du Génie Rurale'' (DGGR). In 1974, ONAS was established to manage the sanitation sector. Since 1993, ONAS got the status of a main operator for protection of water environment and combating pollution. The rate of non-revenue water is the lowest in the region at 21% in 2012.〔 == Access == According to the Joint Monitoring Program by WHO and UNICEF, 96% of the Tunisian population had access to an improved water source and 90% to improved sanitation in 2004. Between 1990 and 2011, access to water increased from 81% to 96%, while the access to sanitation increased from 75% to 90%.〔 Tunisia has achieved the highest access rates to water supply and sanitation services among the MENA countries through sound infrastructure policy. 96% of urban dwellers and 52% of the rural population already have access to improved sanitation. By the end of 2006, access to safe drinking water has been expected to be close to universal (approaching 100% in urban areas and 90% in rural areas).〔 According to the Tunisian Ministry of Development and International Cooperation, in 2006 92.6% of the population had access to drinking water in homes.〔(Tunisian Minsitry of Development and International Cooperation from 2006 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Water supply and sanitation in Tunisia」の詳細全文を読む スポンサード リンク
