World Engineering Day for Sustainable Development 2025: OiEau at the Heart of Innovation for a Sustainable Future

In 2019, UNESCO, during its General Conference, designated March 4 as World Engineering Day for Sustainable Development to raise public awareness about the central role of engineering in mitigating the effects of climate change.
In 2025, the theme of this day is "Unleashing the Power of Engineers in Support of the Sustainable Development Goals." On this occasion, OiEau wishes to emphasize the importance of engineers' role in sustainable water management and the preservation of natural resources. Engineering is a crucial lever in addressing global ecological challenges, particularly regarding water.
Within OiEau, we develop and implement large-scale projects that are part of this dynamic, providing concrete and sustainable solutions for optimized water management while contributing to the ecological transition.
Forecasting to Support Decision-Making
In the context of climate change, projection tools are essential for making informed decisions as they allow for anticipating consequences and evaluating several possible scenarios before making a choice.
The LIFE Eau&Climat project, coordinated by OiEau, aims to assist local water resource management stakeholders in evaluating the impacts of climate change, integrating them into their planning, and implementing adaptation measures, using Explore2 data. It offers, in particular, the Drias-eau portal, which allows for the visualization of hydrological projections.
The ProsperEau tool, developed by OiEau, helps local authorities make relevant strategic and operational choices through modeling and forecasting the financial balance of their water and sanitation services while considering consumption forecast data that includes climatic, economic, and social dimensions.
Training to Evolve Practices
Climate change profoundly impacts the sectors of agriculture, energy, and water, constantly evolving their professions and technologies. Therefore, it is crucial to remain trained and informed throughout one's career to acquire specific skills, adapt practices, and respond effectively to new demands.
For over 40 years, OiEau has supported professionals, including engineers, in strengthening their skills. Recognized for its team of experts, its full-scale installations, and its network of trainers, OiEau offers high-quality, tailored training solutions to meet the specific challenges of each sector.
Data: A Key Element
For over 30 years, OiEau has supported the production of reliable, comparable, and usable water data for public and private stakeholders.
Through SANDRE, OiEau has contributed to the creation and dissemination of the drought alert zone reference used by the VigiEau platform. This online platform allows everyone – individuals, farmers, mayors, and business owners – to monitor local water use restrictions in force in France. It aims to promote sustainable water management and resource conservation. In addition to restrictions, eco-friendly actions to preserve water are also shared on the platform.
Space Engineering for Sustainable Water Resource Management at a Global Scale
By mobilizing cutting-edge technologies for sustainable and shared water resource management on a global scale, the "One Water Vision" coalition demonstrates the essential role of space engineering in sustainable development. In partnership with the World Meteorological Organization (WMO), the INBO, whose Permanent Technical Secretariat is managed by OiEau, launched this ambitious initiative in 2024. It brings together over 20 research institutions. Its goal is to leverage innovative satellite technologies to provide concrete solutions for water resource management, water-related risks, early warning systems, agriculture under water stress, and planning.
