Among the achievements is the expansion of infrastructure to keep pace with population growth, in particular through the construction of the Thika Dam and associated water treatment plant and pipelines during the 1990s; the transformation of the municipal water department into an autonomous utility in 2003; and the more recent reduction of water losses – technically called non-revenue water – from 50 to 40%.〔 Challenges include poor quality and intermittent water supply (only 40% of those with house connections receive water continuously);〔 the loss of storage capacity in reservoirs behind dams through siltation accelerated by erosion in the Aberdare Range;〔 lack of access to adequate sanitation in slums where half the population of the city lives; blockages of sewers resulting in overflows;〔 and unused capacity in the city's largest wastewater treatment plant in Dandora.〔 Another problem is political infighting and corruption, leading to the firing of the entire Board of the Nairobi Water Company in 2009.〔 ==History== The history of water supply to Nairobi since the city was founded as a rail outpost in 1899 has been to a large extent a history of tapping ever more distant water sources to supply a rapidly expanding city with sufficient water. Other challenges faced included the reduction of water distribution losses, reaching the poor in slums, expanding sewerage and wastewater treatment, and strengthening the Nairobi water utility. 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 Nairobi」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
