在撒哈拉以南非洲的农村地区，手泵很常见，10-67%的手泵在任何时候都无法使用，许多手泵从未得到维修。提高可靠性需要改进维护提供商的监控和响应。2014年，卢旺达三个省安装了181个支持蜂窝功能的水泵使用传感器。在三个武器，名义上的维护模式进行了比较，对“最佳实践”的电路骑手模型，和“救护车”的服务模式。只有救护车模型中的传感器数据可供实施者使用，并用于派遣技术人员。该研究在2014-2015年进行了7个月。在研究期间，标称维护组成功修复的中位时间约为152天，平均每泵功能约为68%。在Circuit Rider组中，成功修复的中位时间接近57天，每个泵的功能平均值接近73%。在救护车服务组中，成功的修复间隔时间接近21天，平均功能接近91%。一项指示性成本分析表明，三种型号之间每年每台功能泵的成本大致相似。然而，可靠的供水服务的好处可能证明更注重服务模式而不是安装模式是合理的。
In rural sub-Saharan Africa, where handpumps are common, 10-67% are nonfunctional at any one time, and many never get repaired. Increased reliability requires improved monitoring and responsiveness of maintenance providers. In 2014, 181 cellular enabled water pump use sensors were installed in three provinces of Rwanda. In three arms, the nominal maintenance model was compared against a "best practice" circuit rider model, and an "ambulance" service model. In only the ambulance model was the sensor data available to the implementer, and used to dispatch technicians. The study ran for seven months in 2014-2015. In the study period, the nominal maintenance group had a median time to successful repair of approximately 152 days, with a mean per-pump functionality of about 68%. In the circuit rider group, the median time to successful repair was nearly 57 days, with a per-pump functionality mean of nearly 73%. In the ambulance service group, the successful repair interval was nearly 21 days with a functionality mean of nearly 91%. An indicative cost analysis suggests that the cost per functional pump per year is approximately similar between the three models. However, the benefits of reliable water service may justify greater focus on servicing models over installation models.
