A survey on the functionality of boreholes equipped with hand pumps was undertaken in five districts in Malawi in 2016. The survey aimed at developing a robust evidence-base of the performance of hand pump boreholes by applying a tiered assessment of functionality: (1) working at the time of survey (2) producing the design yield of the borehole; (3) working for >11 months per year and (4) delivering water quality requirements from the World Health Organisation (WHO). This information would guide sustainable future investments in water and sanitation projects. A stratified two-stage random sampling strategy was adopted. The results from the survey indicate that 74% of hand pump boreholes (HPBs) were working at the time of survey; 66% of HPBs passed the design yield of 10 L per minute; 55% met the design yield and also experienced less than one month downtime within a year. Only 43% of HPBs met all the functionality requirements including WHOguidelines for drinking water quality. The survey also assessed the village-level Water Management Arrangements at each water point. Results indicate that the majority of the Water Management Arrangements (86%) are functional or highly functional. The initial exploration of the data shows no simple relationship between the physical functionality and Water Management Arrangements.

马拉维手动泵钻孔功能分析

2016年在马拉维的五个地区对配备有手动泵的钻孔的功能进行了调查。该调查旨在通过对功能进行分级评估,为手动泵钻孔的性能建立有力的证据基础:(1)工作在勘测时(2)产生钻孔的设计产量;(3)每年工作超过11个月,(4)达到世界卫生组织(WHO)的水质要求。这些信息将指导未来在水和卫生项目上的可持续投资。采用分层两阶段随机抽样策略。调查结果表明,在进行调查时,有74%的手动泵钻孔(HPB)正在工作。66%的HPB通过了每分钟10 L的设计产量;55%达到了设计良率,并且一年内停机时间不到一个月。只有43%的HPB满足了所有功能要求,包括WHO的饮用水水质准则。调查还评估了每个供水点的村级水管理安排。结果表明,大多数水管理安排(86%)都具有功能性或高度功能性。数据的初步探索表明,物理功能与水管理安排之间没有简单的关系。结果表明,大多数水管理安排(86%)具有功能性或高度功能性。数据的初步探索表明,物理功能与水管理安排之间没有简单的关系。结果表明,大多数水管理安排(86%)都具有功能性或高度功能性。数据的初步探索表明,物理功能与水管理安排之间没有简单的关系。
