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持续稳定地提供清洁饮用水。在此类应用场景中，对这些方案的实际效能进行评估并充分考量其潜在影响，实属必要之举。本研究对加纳一家采用太阳能水处理技术、巡回服务准则、预付费计量系统以及全辖区统筹运营模式的私营供水企业开展了为期三年的跟踪评估。研究采用准实验研究设计，通过关键知情人访谈、家庭入户调查与水质检测，探究不同管理模式下家庭所获取的供水服务质量，并运用逻辑回归分析对各项服务指标进行对比分析。
