nawatech logo  webThe project NaWaTech "Natural Water Systems and Treatment Technologies to cope with Water Shortages in Urbanised Areas in India" aims to explore, assess and enhance the potential of natural and compact technical water treatment systems, in order to improve their performance and reliability for the effective management of municipal water sources and to cope with water shortages in urban India.  The specific objectives of NaWaTech are: (i) assess the technical, financial and environmental potential of natural and technical water treatment technologies to cope with water shortages in urbanised areas in India; (ii) enhance the natural and technical water treatment systems for the production of recycled water to supplement water sources considering extreme climatic conditions and highly varying pollutions loads; (iii) disseminate, exploit and ensure the take- up in practice and mainstreaming of NaWaTech activities and outputs by key stakeholders; (iv) benefit SMEs in the water sector by supporting the development of a local market for innovative water treatment technologies, and to train the SMEs on the NaWaTech approach; (v) establish foundations of a long-term cooperation between EU and India in water technologies.

An international team composed by 7 European partners, coordinated by the ttz-Bremerhaven and 7 Indian partners, coordinated by NEERI work on the adaptation of different natural and compact water systems to the Indian context during the 3 year lifetime of NaWaTech. NaWaTech was one of the 5 projects of the funding scheme shared by EU and India in the section "EU-India cooperation in water technology and managment: research and innovation", where EU partners were funded by the 7th Framework Programme (FP7). The project starded in 2012 and ended in 2015.

IRIDRA was involved as partner of the NaWaTech project. IRIDRA designed and disseminated results of different pilot systems, which were realized in India and wanted to reduce water shortage in urbanized Indian areas (constructed wetland and green walls for treatment and reuse of wastewater). Moreover, IRIDRA contributed in the organization of courses, aimed to tranfer knowledge to local stakeholders and designers. The courses were related to sustainable sanitation and sustainable water management.
