Water supply in Southern Sudan is faced with numerous challenges. Although the White Nile runs through the country, water is scarce during the dry season in areas that are not located on the river. About half the population does not have access to an improved water source, defined as a protected well, standpipe or a handpump within 1 km. The few existing piped water supply systems are often not well maintained and the water they provide is often not safe to drink. Displaced people returning home put a huge strain on infrastructure, and the government institutions in charge of the sector are weak. Substantial external funding from numerous government agencies and non-governmental organizations is available to improve water supply. == Water resources == Rainfall in Southern Sudan is highly seasonal, with a rainy season between July and October. In the extreme South of the country there is also a second rainy season from March to May. Groundwater is an important source of water supply for people and livestock, especially during the dry season. In some areas groundwater is brackish, groundwater yields are low and the success rate for well drilling is low.〔Government of Southern Sudan:Rural Water Supply and Sanitation Project:(Frequently Asked Questions:Which areas have low/poor ground water yield and why? ), retrieved on May 22, 2011〕 The main river is the White Nile, which enters the country from Uganda in the South and flows to Sudan in the North. The new country’s capital, Juba, as well as other cities such as Bor and Malakal are located on the river. Most rivers besides the Nile, such as the Bahr el Ghazal River, the Sobat River and their tributaries, disappear during the dry season. The White Nile and the Bahr el Ghazal River flow in the Sudd, a large seasonal swamp in the heart of the country. 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 in South Sudan」の詳細全文を読む スポンサード リンク
