While access to drinking water has expanded worldwide, safely managed provision is still a challenge, and rural areas are specially underserved. To provide safe drinking water for these areas, water scholars and international organizations have advocated for community-based organizations or coproduction schemes. The literature often mentions that institutions and people play a key role in the provision of drinking water although the specific mechanisms through which they may affect the process of maintaining good quality water have not been reported yet. The article aims to fill this gap by providing a complex, local view on this process. In Chile, from 1960 onwards, the State has implemented cooperatives to provide for drinking water in rural and small-town areas under a coproduction scheme. In this scheme, the State provides the infrastructure, and the community is responsible for service provision. We analysed the water quality of six of these cooperatives and conducted interviews with water managers and leaders. Our research suggests that formal and informal relationships provide the links and motivation needed for the organizations continuous work. These results highlight how relevant it is to keep in mind the context and the public role of delivering safe drinking water.
