The Problem

Essential infrastructure is sitting on unrealized value. We unlock it.

The Cost Trap Municipal wastewater facilities are cost centers by design — paying escalating disposal fees, forfeiting energy daily, and managing aging infrastructure on constrained budgets. What's treated as waste is actually stranded value, and the gap between what's needed and what's funded grows every year.
Stranded Value Seven times more energy flows through a wastewater plant than is used to power it. Recoverable energy, heat, and nutrients go unrealized every day — not for lack of technology, but for lack of the right capital and partnership.3
The Capital Gap Utilities face structural constraints — ratepayer reliance, debt limits, and uneven capital market access — that widen the investment gap and heighten risks to system reliability.4 These projects are too small for Wall Street and too complex for Main Street.
Our Solution

Turning municipal waste streams into energy, value, and resilience

Private capital can accelerate delivery, transfer risk, and unlock circular value when paired with strong governance.4 Estian provides exactly that by retrofitting water and wastewater facilities for resource recovery, turning cost centers into sources of energy independence and long-term resilience, for municipalities and investors alike.

Our Ethos

The principles we build on

Every decision we make flows from three core beliefs.

Local Stewardship

Capital is a tool; community trust is the foundation. We are trusted partners to local service providers in protecting and modernizing essential public assets.

Infrastructure Resilience

We see infrastructure as dynamic, not static. We leverage proven energy and resource recovery technology to transform public liabilities into productive, resilient assets.

Aligned Partnership

True value emerges where public needs and private capital unite. We build partnerships founded on shared interests, ensuring municipalities, rate-payers, and investors all succeed together.
