Evaluating the level of household water service provided by a private water enterprise in Ghana

Innovative service delivery models are attempting to more consistently provide clean water to communities in developing countries. It is imperative that these approaches be evaluated for their performance in these contexts while understating potential consequences. A private company in Ghana utilizing solar-powered water treatment, circuit rider principles, pre-paid metering, and a district-wide approach was assessed for three years. A quasi-experimental design used key informant surveys, household surveys, and water quality testing to investigate the service received by households under various management schemes. Service indicators were compared using logistic regression analysis.创新型供水服务模式正致力于为发展中国家的社区提供更为稳定的清洁饮用水供给。在此类应用场景中，对这些方法的绩效开展评估的同时，亦需明晰其潜在后果。加纳一家采用太阳能水处理、巡回运维模式、预付费计量以及全区域统筹运营模式的私营企业，接受了为期三年的绩效评估。本研究采用类实验设计，通过关键知情人访谈、家庭入户调查及水质检测，对不同管理模式下的家庭所获供水服务展开调研，并运用逻辑回归分析对各项服务指标进行对比分析。
