Design of a decentralized and sustainable gravity-fed drinking water supply system: the case of San Marino, Bagadó, Chocó Village

San Marino (Bagadó - Chocó) is a community that has been affected by violence in the recent past. All of its social development indicators are unsatisfactory, especially the lack of infrastructure and access to potable water and proper sanitation, which has led to cases of morbidity and mortality associated with water-related diseases, especially among children and the elderly. This project proposes an integrated drinking water supply solution, using appropriate technology for the quality of water from the Andágueda River, and adapted to the socioeconomic conditions of the population, seeking to significantly improve their quality of life. In this sense, the project contributes mainly to the fulfillment of SDG 6, and is aligned with the commitments made by Colombia for the year 2030. After evaluating different alternatives through engineering calculations, computer programs and other socioeconomic, normative and environmental considerations, a conventional treatment system operated entirely by gravity was selected as the most appropriate for the case. The results showed that, by means of the offered solution, it is feasible to obtain competitive production costs ($ 300/m3) and initial investment ($ 2.443 million), when compared to electrified solutions, without compromising the quality of the permanent provision of the service, generating important savings and benefits for the township in terms of operation and maintenance, as well as greater management sustainability in general. It is hoped that the proposal can be applied in other remote communities in the country with similar characteristics and problems.
