LOW-COST INNOVATIVE TECHNOLOGY FOR WATER QUALITY MONITORING AND WATER RESOURCES MANAGEMENT FOR URBAN AND RURAL WATER SYSTEMS IN INDIA
Co-creation of innovative low-cost technology for India’s water challenges

LOTUS is a project funded by DG Environment under the European Union Horizon 2020 Research and Innovation Programme and by the Indian Government. It brings together EU and Indian prominent organisations with the aim to co-create, co-design and co-develop innovative robust affordable low-cost sensing solutions for enhancing India’s water and sanitation challenges in both rural and urban area.

India must address serious challenges regarding the quality of water: among other issues, only 30% of the population has access to treated drinking water and more than 37 million Indians per year suffer from waterborne diseases. With focus on co-development between EU and India ensuring exploitability of its outcomes, LOTUS brings a new ICT solution for India’s water and sanitation challenges in both rural and urban areas.

LOTUS will develop and test in several use cases both, solutions for early detection of water quality problems and decision support for countermeasures and optimal management of drinking and irrigation water systems.

In this project, IMSE is responsible for the development of LOTUS multiparameter sensors (WP Leader). Results of the project are documented in the project news here: https://www.lotus-india.eu/index.php/event-news/
