【 摘 要 】

Statistics on the functionality of water points from the Hidden Crisis project in Uganda are presented.The survey, undertaken in 2016, was focussed on boreholes equipped with handpumps (HPBs) within the 112 districts of Uganda.A stratified two stage random sampling approach was adopted and 10 districts identified to sample.A tiered definition of functionality was applied, and all which enabled more nuanced definitions to be reported: The results from the survey indicate:鈥?55% of HPBs were working on the day of the survey (compared to national figure of 86% for rural water supply) 鈥?34% of HPBs passed the design yield of 10 litres per minute鈥?23% passed the design yield and also experienced < 1 month downtime within a year.鈥?18% passed the design yield and reliability criteria and also water quality criteriaThe results of the survey indicate the utility of carrying out more detailed assessments of functionality to help unpack national statistics. A linked survey of the performance of the water management arrangements at water points showed that for 70% of the sites water management arrangements were judged to be weak.
