STP with ZERO CapEx? Yes.

In India’s urban centres, regulatory pressure on wastewater management is intensifying. Resident Welfare Associations (RWAs), commercial complexes, and institutions are investing heavily in Sewage Treatment Plants (STPs) to meet PCB mandates and promote sustainability. Traditionally, these plants are purchased and installed under a CapEx model, where the client bears the upfront cost and responsibility for long-term operations.

At Banka Bio, we’ve worked with hundreds of clients under this model.

But today, we invite you to pause and ask: Is CapEx always the best way forward?

The Promise (and Pitfalls) of the CapEx STP Model

When you opt for the CapEx model, you buy the system outright. On paper, this gives you full control. But in practice, it also means:

Heavy upfront investment
Responsibility for performance, uptime, and compliance
Hiring or outsourcing O&M staff
Time spent managing vendors, breakdowns, and audits

For many RWAs and facility owners, the result is unfortunately familiar: a non-performing STP that drains funds, misses compliance, and causes headaches.

Enter Megaliter Varunaa: A Smarter Way to Run Your STP

To solve this, we bring to you Megaliter Varunaa—a next-generation solution offering “STP as a Service”. Under this model:

We invest in your STP (retrofit or build)
We operate it under strict performance guarantees
You pay a monthly service fee, just like a utility bill

This O&M-based model shifts the risk and responsibility off your plate and ensures your plant always works, always stays compliant, treats 100% of your wastewater, and provides long-term water security.

Still Want to Own Your STP?

We understand—some clients prefer the CapEx for STP. If you're one of them, Banka Bio is here to help with:

But if you're tired of the stress and sunk costs, maybe it’s time to let go of ownership and just enjoy the service.
