Survival skills
A human being can survive an average of three to five days without the intake of water. The issues presented by the need for water dictate that unnecessary water loss by perspiration be avoided in survival situations. The need for water increases with exercise.
Water supply and sanitation in Kenya
Continuity of supply. The 2015 Impact Report reports an average supply of 18 hours per day, up from 14 hours in 2006-07. Only in nine mostly small WSPs water is provided continuously 24 hours per day. In Nairobi water is provided on average for 18 hours a day and in Mombasa for 6 hours. Nonetheless, instances of water scarcity (defined as more than five days without or with insufficient water supply) still occur in Kenya. In 2006 in Kisumu over 40% of households (both poor and non-poor) connected to water mains reported scarcity. The greatest difference between the poor and non-poor was recorded in Nairobi, where poor households were more than twice as likely to say they experienced scarcity. A higher percentage of kiosk users reported scarcity than households with mains connections, suggesting that in times of scarcity kiosks are less likely to receive water than domestic connections.
