1.1.5 Improving urban water system efficiency The SAPHE project in South Tarawa dramatically decreased water losses from the rising main between Bonriki and Teaoraereke. The KWASP project in Kiritimati similarly improved water supply. Unaccounted for water through leakages, however, remains unacceptably high within village and town distribution systems, particularly in Betio and Banana. Significant gains in efficiency and therefore in cost recovery can be made by reducing levels of water losses. 1.1.6 Rainwater sources
