HA Sustainable Infrastructure Capital, Inc. ("HASI") (NYSE:<a class="ticker" href="https://www.benzinga.com/quote/HASI">HASI</a>), a leading investor in sustainable infrastructure assets, and Burnham, a developer, owner, and operator of wastewater treatment and reuse infrastructure, today announced the closing of a structured equity investment in the Pasco Resource Recovery Center ("Pasco Center"), a wastewater treatment and reuse facility serving the City of Pasco in Washington State.

</p><p xmlns="http://www.w3.org/1999/xhtml">
Developed, owned, and operated by Burnham, the Pasco Center provides wastewater treatment and reuse services for seven local industrial food-processing plants. The facility uses anaerobic digestion to break down organic matter in wastewater and has the capacity to recycle more than one billion gallons of water annually for agricultural irrigation. In addition to generating reusable water, the Pasco Center also produces renewable natural gas ("RNG") as a saleable byproduct. The facility further supports resource recovery by producing nutrient-rich soil amendments.

</p><p xmlns="http://www.w3.org/1999/xhtml">
As a partnership between Burnham and the City of Pasco, the Pasco Center replaced Pasco’s original Process Water Reuse Facility in 2025, significantly increasing its wastewater processing capacity and reducing its environmental impact. Output from the upgraded facility is used to irrigate 1,900 acres of agricultural fields owned by the City of Pasco.

</p><p xmlns="http://www.w3.org/1999/xhtml">
HASI’s investment, which closed in July 2026, marks its first transaction in water infrastructure and reflects the company’s continued focus on sustainable infrastructure assets with long-term, contracted cash flows and measurable environmental benefits. The investment is supported by a 30-year wastewater treatment agreement with the City of Pasco.

</p><p xmlns="http://www.w3.org/1999/xhtml">
"HASI is excited to invest in this innovative facility, which not only returns clean water for agricultural use, improves air quality, and reduces emissions in the Pasco area, but also produces RNG to decarbonize the local economy," said Annmarie Reynolds, HASI’s Co-Chief Investment Officer. "We look forward to investing further into water infrastructure and broadening our impact."

</p><p xmlns="http://www.w3.org/1999/xhtml">
"The Pasco Center is exactly the kind of project Burnham was built to deliver — turning a wastewater challenge into clean, reusable water and a source of renewable energy for the community," said Chris Tynan, Burnham’s Chief Executive Officer. "HASI’s investment positions us to bring similar solutions to other public utilities facing water and wastewater challenges. We see this as a strong first step with HASI, and we are optimistic there will be more opportunities to partner as our platform continues to grow."
