HASI Invests in Washington Wastewater Treatment and Water Reuse Facility
HA Sustainable Infrastructure Capital (HASI) made its first water-sector investment, a structured equity deal in Burnham’s Pasco Resource Recovery Center in Pasco, Washington. The facility can recycle over 1 billion gallons annually, producing renewable natural gas and agricultural soil amendments. Terms were undisclosed, and a 30-year city agreement underpins contracted revenue.
How this was made

The 30-second read
Why it matters
The Pasco Resource Recovery Center is positioned as resource-recovery infrastructure: industrial wastewater treatment with large-scale water reuse, renewable natural gas production, and nutrient-rich soil amendments, under a 30-year city agreement.
Market read
Traders may view the deal as incremental portfolio diversification into long-lived, contracted municipal water assets with RNG co-production, but the lack of disclosed economics limits immediate re-pricing.
What to watch
RNG pricing, offtake/saleability assumptions, and regulatory or operational performance of the anaerobic digestion system could dominate returns more than the headline capacity figure.
Background
HASI is a sustainable infrastructure investor with a portfolio spanning utility-scale solar, storage, wind, distributed solar, RNG, and energy efficiency; this is its first reported water-infrastructure investment.
Ticker impact
HASI closed a structured equity investment in the Pasco Resource Recovery Center, adding a 30-year contracted wastewater and RNG revenue exposure.
Near-term impact likely modest unless investors re-rate HASI’s growth runway in water/RNG; longer-term could support a steadier contracted-cash-flow narrative.
The article discloses the investment and the 30-year wastewater treatment agreement, but provides no deal size or financial terms, limiting immediate valuation impact.
Market effects
Highlights growing investor interest in wastewater-to-resource recovery projects combining water reuse, RNG, and nutrient recovery.
Pasco, Washington project supports local agricultural irrigation and emissions reduction claims under a long-term municipal agreement.
Reinforces the broader decarbonization and water-security investment theme, though the deal is geographically specific.
Counterpoint
Without disclosed financial terms, the investment may be strategically meaningful but not material to HASI’s near-term earnings or NAV.
