Ignacio
MAGNANI
Water Resources Specialist / Water Supply and Sanitation Engineer
8 years of professional experience
Ignacio joined Hydroconseil to work in the water resources sector, where he provides conceptual and numerical water cycle modelling support and conducts research on Nature-Based Solutions.
He has worked on projects that conducted hydrological and hydraulic simulations for flood risk management in vulnerable communities. In the southern region of Madagascar, he undertook two hydrogeological studies on extracting groundwater to enhance climate change resilience for sustainable water supply production. His approach often combines both on-site and remote sensing data to assess water flow through conceptual and numerical modelling. His resulting versatility and understanding of the potential impact of climate change within the water cycle also led to his involvement in a water harvesting project in Mexico for over twenty water stressed communities located in coastal and mountainous areas.
On the academic side, Ignacio was awarded an Erasmus Mundus scholarship to complete the Erasmus Mundus Hydroinformatics & Water Management MSc (EuroAquae), studying in key universities in Spain, the UK, Germany, Poland and France. This training provided him with a toolset of hydro-informatics skills that he has been able to apply to water management.
Ignacio also holds a Civil Engineering degree from the University of Buenos Aires. He worked in Argentina for 4 years as an engineer in a range of fields, including transport planning, civil construction site management and hydraulics, and in both the private and public sector. One of his positions included working as a junior water supply / sanitation engineer designing water, sanitation and stormwater drainage for around ten small cities in Argentina.

Sebastián
PRUDENCIO
Water and sanitation Expert
Less than 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 Hydroconseil team as a junior water and wastewater expert, lending his wide range of skills to drinking water supply projects, particularly in Iraq.
