Sebastián
PRUDENCIO
Water and sanitation Expert
1 year of professional experience
A water and environmental engineer, Sebastián’s skillset covers water management, treatment and governance, as well as the waste and environment sector. Autonomous and highly adaptable, in 2020 he worked on a project to analyse hydrological flows in one of the catchment areas of Lake Titicaca in Bolivia, and was also involved in conducting the institutional assessment (stakeholder mapping, economic analysis) and defining the social and environmental implications of weaknesses in local governance (particularly water pollution) in a cross-border setting (Bolivia, Peru). In 2021, Sebastián spent time working in the field in a community in Bolivia (Bolivian Yungas) collecting data from residents. He thus made a valuable contribution to a project to ensure the community’s continued access to drinking water, and also remedied the lack of water supply system documentation by mapping the infrastructure and identifying issues. In Sweden, Sebastián worked in a research laboratory studying the influence of riparian areas on watercourses, which required dual expertise in soil and hydrogeology in order to analyse soil and groundwater levels. He also made a decisive contribution to a project to install and assess an innovative disinfection system, which was placed at a wastewater treatment plant outlet and based on Constructed Wetlands technology. In 2024, he joined the Global Development team as a junior water and wastewater expert, lending his wide range of skills to drinking water supply projects, particularly in Iraq.
