SciencePiyush Jha's Affordable Wastewater System Recognized by UNDP
Piyush Jha, a 20-year-old from Madhubani, Bihar, developed an affordable and unique wastewater treatment system that earned recognition from the United Nations Development Programme (UNDP). After moving to Mumbai, he witnessed poor sanitation in slums causing diseases like dengue and typhoid. Without formal engineering education, Piyush designed a decentralized, chemical-free system reducing costs from 20 lakh to 5-7 lakh rupees, aiding small industries and improving public health.
