Welcome to the website of SusPaani [ Sustainable Paani (water) ] Lab at the Centre for Sustainable Technologies, Indian Institute of Science, Bangalore. 

Water resources are limited and life without water is impossible. SusPaani Lab engages in research on: 

(i) sustainable treatment solutions for making this precious resource available (in adequate quantity and quality) for sustainable consumption, and 

(ii) sustainable wastewater treatment technologies for safeguarding and replenishing our precious water resources. 

You are invited to explore our website to get to know about our research focus, projects, industry collaboration and translational works.
