Tharun Kumar

Engineer with 20+ years of experience in sustainability and cybersecurity. Founded EcoSTP in 2017 after identifying that 70% of India's sewage goes untreated. Recognised by the UN ESCAP 8th World Water Forum.

EcoSTP builds decentralised, nature-based sewage treatment systems inspired by a cow's stomach — using microorganisms, plants, and gravel. Zero power. Zero operator. IoT-enabled. Deployed across 25 Indian states, processing billions of litres of sewage.

India processes less than 30% of its sewage. Conventional STPs require massive power and maintenance — making them impractical for the 600,000+ villages that generate most of the pollution.
