Urban water management-focused startup Megaliter Varunaa has raised Rs 15 crore in a seed funding round from long-term Institutional Investors.

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.”

The Hyderabad-based Megaliter Varunaa, a subsidiary of Banka BioLoo Limited, operates a business model that enhances urban water resilience by maximising wastewater reuse while minimising the need for freshwater.

Megaliter Varunaa converts sewage treatment plants (STPs) into circular water utilities through its flagship ‘Megaliter Model’ — a zero-CapEx, subscription-based solution that maximizes wastewater reuse. With long-term, end-to-end service contracts, it offers a fully integrated solution covering financial, operational, and compliance aspects.

This model ensures reliable and sustainable water recycling for non-potable uses like flushing, gardening and chiller systems, reducing urban dependence on freshwater and unlocking new value from wastewater.
