Eleven-year-old launches water conservation network across India

Nithya Tammana, an 11-year-old environmental activist, has emerged as a leading voice in India's water conservation movement after establishing Save Drop, a grassroots initiative that has enlisted more than 450 young changemakers committed to tackling water scarcity and pollution.

Observing the extent of water wastage in her own household, Tammana recognised the urgent need for systematic behavioral change around water consumption. Her platform has galvanised hundreds of young volunteers to launch awareness campaigns and implement practical conservation strategies within their communities, emphasising how individual habits directly impact broader water security challenges across the country.

Beyond advocacy work, Tammana has developed BioLayer, a nature-inspired water filtration system designed to address contamination issues in educational institutions. The technology targets removal of hazardous substances, including lead, from drinking water sources in schools, where access to clean water remains inconsistent across many Indian regions.

Tammana's dual approach—combining community mobilisation with technological innovation—has garnered recognition for her contributions to environmental sustainability. Her work reflects growing momentum among India's youth to drive tangible solutions to water-related challenges, demonstrating how young innovators can scale impact through organised networks and scientific approaches to public health issues.
