Urine diversion, also called urine separation or source separation, refers to the separate collection of human urine and feces at the point of their production, i.e. at the toilet or urinal. Separation of urine from feces allows human waste to be treated separately and used as a potential resource.〔von Münch, E., Winker, M. (2011). (Technology review of urine diversion components - Overview on urine diversion components such as waterless urinals, urine diversion toilets, urine storage and reuse systems. ) Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH〕 Applications are typically found where connection to a sewer-based sanitation system is not available or areas where water supplies are limited. To achieve urine diversion, the following technical components are used: waterless urinals, urine diversion toilets, urine piping to a urine storage tank (or to a sewer) and a reuse or treatment and dispoal system for the urine. Urine diversion toilets may, or may not, mix water and feces, or some water and urine. They never mix urine and feces. A toilet used to facilitate the separation of human waste products is called a urine diversion toilet or UDT. The bowl usually has two separate receptacles which may or may not be flushed with water. If flushed, the toilet is usually referred to as a UD flush toilet or UDT. If not flushed, it is a dry toilet with either drying or composting for the feces. If the collected feces are dried, it is called a urine-diverting dry toilet or UDDT (also called urine diversion dehydration toilet).〔Rieck, C., von Münch, E., Hoffmann, H. (2012). (Technology review of urine-diverting dry toilets (UDDTs) - Overview on design, management, maintenance and costs. ) Deutsche Gesellschaft fuer Internationale Zusammenarbeit (GIZ) GmbH, Eschborn, Germany〕 If the collected feces are composted. it is called a urine-diverting composting toilet. Some technologies applied as part of an ecological sanitation concept are using urine diversion. There are several commercially available urine diversion toilets (UDT) and urine diversion dry toilets (UDDT). Many look like a conventional sit-down or squat toilet and the bowl is divided into two sections, with the front section collecting urine and the rear section feces. == Design considerations == 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「Urine diversion」の詳細全文を読む スポンサード リンク
