Harris F. Seidel (1922–2025) devoted more than a century of his life to strengthening the water and wastewater profession through vision, service, and a steadfast commitment to community. He is remembered not only as a co-founder of the North American Association of Boards of Certification (ABC)—today known as Water Professionals International (WPI)—but also as a talented writer, servant leader, and mentor whose influence shaped generations of water professionals.
Building a Framework for Certification
In 1972, Seidel helped establish ABC, serving as its first President and later as executive director. Under his leadership, the organization developed consistent standards that elevated operator certification across North America. These efforts positioned ABC, now WPI, as a central force in ensuring the competence and professionalism of water environment operators.
His influence extended far beyond certification. Seidel led the Water Environment Federation (WEF) as its national President in 1963–64 and guided both the Iowa Section of the American Society of Civil Engineers and the Iowa Section of the American Water Works Association. Closer to home, he served nearly four decades as the City of Ames’ Director of Water and Pollution Control, from 1954 until 1991. His expertise was also sought globally; he advised on projects in over 20 countries through his work with the World Bank and other agencies. Together, these roles cemented his reputation as a founding father of modern water and wastewater operator certification and a respected leader in the global water community.
A Writer and Servant Leader
Seidel’s leadership was matched by his gift for writing. He authored more than 30 published papers on topics such as water rates, metering, and operator training, and he produced a comprehensive history of the Ames Water Department—a project described as a true “labor of love” that preserved local waterworks heritage. His writing was both technical and visionary, often urging the industry to embrace higher standards. In a 2014 WaterWorld’s Editor’s Letter, he lamented the patchwork of state certification programs and urged that “we owe it to the people we serve to get our act together… to get our programs generally on the same page,” issuing a challenge to “dislodge” inconsistent standards.
Yet it was his character as a servant leader that left the most profound impression. Seidel mentored countless young professionals, encouraged operator training at every turn, and continued to offer guidance; this included writing advice to colleagues in the water and wastewater community well into his later years. Colleagues and friends noted that he was unwavering in his dedication to strengthening the industry and championing its operators.
Awards and Tributes
Seidel’s impact was so profound that multiple awards now carry his name, ensuring his values live on.
The Harris F. Seidel Education Award (Iowa WEA)
Created by the Iowa Water Environment Association, this award celebrates Seidel’s lifelong passion for mentoring and developing future water professionals. It is presented to individuals who demonstrate exceptional commitment to training and educating new operators. The award underscores his belief that the industry’s future rests in the knowledge, skills, and confidence of its workforce. By naming this award in his honor, Iowa WEA ensures that his dedication to operator training continues to be celebrated each year.
The Harris F. Seidel Lifetime Achievement Award (WPI)
This is the highest honor presented by Water Professionals International. Established by WPI’s Board of Directors, it recognizes individuals whose entire careers have been devoted to advancing environmental professional certification. Recipients are chosen for sustained contributions and leadership, as well as for creating resources and programs that strengthen the workforce globally.
Presented annually at WPI’s conference, it has recognized many of the industry’s most influential leaders. Each recipient embodies the qualities Seidel himself championed: innovation, impact beyond local boundaries, and a career dedicated to elevating the profession.
Together, these two awards—one focused on developing new professionals, the other on honoring lifetime service—capture the full spectrum of Seidel’s legacy. They ensure that both emerging and veteran leaders continue to be inspired by his example.
Lasting Impact
Seidel’s influence was also recognized formally when he was inducted into Iowa State University’s Engineering Hall of Fame in 2021. The honor celebrated his “international impact and dedication to the water profession,” acknowledging decades of effort to improve access to safe, reliable water.
Yet beyond titles and awards, Seidel’s legacy lives in the stories told by colleagues and friends. He was remembered not only for technical excellence but also for his humility, warmth, and generosity of spirit. Peers often speak of Seidel as a mentor who freely gave advice, a visionary who saw the big picture for water utilities, and a friend who could craft a witty turn of phrase or heartfelt letter.
Paul Bishop, President and CEO of WPI, even credits Seidel for his current position, saying, “I owe him everything.” Bishop goes on to say,
“Harris was a remarkable man and human. He was a gentleman in every aspect of his life and his love of learning has left a lasting legacy for the people he encountered and the organizations he served. He truly embodied servant leadership and his counsel will be missed, but lives on in all of us who were blessed to know him.”
He led by example, encouraged collaboration, and celebrated the success of others. His encouragement, whether in speeches, articles, or simple letters, remains a hallmark of his leadership.
