Megaliter Varunaa, a startup working on urban water management, has raised INR 15 crore in seed funding from long-term institutional investors.
The new funds will help the company develop new projects and expand using the Megaliter Model — a subscription-based system that doesn’t require upfront investment and turns sewage treatment plants into useful, circular water utilities.
Vishal Murarka, Managing Director, Megaliter Varunaa, said, “This seed capital marks a pivotal milestone in our journey to meet India’s pressing need for sustainable water solutions. Our ongoing mission is to convert underutilised assets into efficient, compliant, and resilient urban water utilities. To date, we have treated over 3 billion liters of wastewater, and our current capacity exceeds 2.5 billion liters annually. In the next 12 months, we aim to build projects to recycle more than 10 billion liters annually, directly enhancing water resilience for cities and reducing freshwater dependency.”
Abhay Garg, Chief Mentor at Brigade REAP, stated, “Megaliter Varunaa exemplifies the kind of sustainable impact-driven innovation India urgently needs. Their model doesn’t just fix broken infrastructure, but rather reimagines it through a lens of circularity, reliability and climate resilience.”
“At Brigade REAP, our support goes beyond mentorship; we refine their go-to-market approach and align their innovation with real-world urban challenges. Our engagement with Megaliter has focused on helping them navigate complex stakeholder ecosystems, unlock scalable partnerships, and position wastewater as a viable utility service.”
Hyderabad-based Megaliter Varunaa, a subsidiary of Banka BioLoo Limited, works to improve urban water management by reusing wastewater and reducing the need for fresh water.
The company transforms sewage treatment plants (STPs) into circular water utilities using its Megaliter Model — a subscription-based system that requires no upfront investment. This model focuses on maximizing wastewater reuse and provides long-term, complete service contracts covering financial, operational, and regulatory aspects.
This model provides a reliable and eco-friendly way to recycle water for uses like toilet flushing, gardening, and cooling systems. It helps cities use less freshwater and makes wastewater more valuable.
