Farming, Methane, and Partnerships: The New Age of Wastewater with Matt Stouder

In this episode of 21st Century Water, we sit down with Matt Stouder, Executive Officer of the Metropolitan Wastewater Management Commission (MWMC) in Oregon, to explore how his leadership is driving operational resilience, environmental stewardship, and innovative thinking in wastewater management. We begin by learning how Matt’s rural upbringing and early exposure to water chemistry inspired a lifelong commitment to environmental protection and public service. His path from stormwater engineering to leading a regional utility reflects a deep-rooted belief in stewardship, collaboration, and giving back to the community.

We then dive into the scale and structure of MWMC, which serves about 275,000 residents across Eugene and Springfield. Despite owning over $500 million in assets and operating a major treatment plant with a peak capacity of 277 MGD, the commission itself has no employees and operates through intergovernmental agreements—Springfield handles the administration and capital projects, and Eugene manages the operations. Matt emphasizes how strategic coordination is key to balancing daily operations with long-term capital investments, especially as the infrastructure ages.

We discuss MWMC’s shift from expansion to asset renewal, including a strong focus on asset management and funding strategies. Incremental rate increases and a rate stabilization fund have helped buffer financial volatility, allowing the utility to maintain steady investment without burdening ratepayers. Matt also shares MWMC’s approach to innovation through projects like the biocycle farm, where biosolids are applied to hybrid poplar trees for local reuse, and a renewable natural gas facility that generates new revenue streams while reducing emissions.

Communication and education emerge as central themes. From community partnerships and public outreach at local fairs to an award-winning Clean Water University program for fifth graders, MWMC prioritizes transparency and awareness. Matt's engineering background doesn't limit his commitment to public engagement; instead, it reinforces it.

As we shift to environmental goals, Matt outlines how MWMC embraces a circular economy mindset. Instead of costly infrastructure like chillers, the utility addresses thermal pollution by planting trees along the McKenzie River, effectively reducing river temperatures while supporting watershed health. He also highlights how climate change is affecting local precipitation patterns, forcing the utility to adjust infrastructure capacity and operational readiness.

Looking ahead, Matt is focused on a $300 million infrastructure renewal plan, transforming biosolids into a higher-value Class A product, and potentially expanding MWMC’s services to nearby communities through regionalization. He views himself as a custodian of the system, aiming to leave the utility stronger than he found it and prepared for the next generation.
