How do you navigate the engineering, regulatory and operational demands of modern water infrastructure?

Based in Portland, Oregon, she brings a powerful combination of technical expertise and strategic leadership to every engagement — from planning biosolids reuse programs to managing half-billion-dollar treatment expansions. Her work consistently aligns infrastructure investment with regulatory certainty and system reliability.

Collaboration defines her approach. She builds and leads high-performing multidisciplinary teams, guiding subconsultants, stakeholder engagement efforts and permitting negotiations across federal, state and local agencies. Her ability to navigate complexity while maintaining alignment keeps large programs moving forward through open communication and thoughtful organization.

Quitterie’s experience spans municipal, industrial and agricultural systems across the western United States and South America. From feasibility studies and engineering design to construction management, Quitterie applies innovative thinking to solve complex client challenges and strengthen long-term outcomes.

In Oregon, she played a central role in managing the City of Portland’s $500 million Secondary Treatment Expansion Program from planning through design and construction. The program met critical regulatory deadlines while positioning the city for sustained system performance. Across her portfolio, she has advanced capital improvements that enhance reliability, strengthen operations and maintenance strategies, and support biosolids land application, treated effluent discharge and natural treatment systems.

Having lived and worked in France, Thailand, South America and the United States, Quitterie brings a global perspective to local infrastructure challenges. She understands how water systems operate within diverse political and economic environments — and translates that insight into practical, community-centered solutions.
