The equitable and universal provision of safe and affordable water is one of the Sustainable Development Goals, but progress has been slow, especially in Sub-Saharan Africa. This paper presents a case study of Dar es Salaam, Tanzania, to highlight water access progress at the city scale. Using household surveys and interviews with officials, it explains improvements in hours of water availability and numbers of household water connections, but also discusses the remaining challenges with water cost and customer satisfaction. To achieve the goal of universal access, the city must further increase water production and address concerns with how water quality is monitored. [ABSTRACT FROM AUTHOR]
