About Seth

Seth has 25 years of experience leading, consulting with, and regulating utilities and public agencies of all sizes, both public and private. He combines over 15 years of hands-on experience as the former General Manager of a regional utility and as a board member of two water and wastewater utilities, with an additional 15 years of consulting experience advising several of the largest and best-known utilities in the U.S., the U.S. Agency for International Development (USAID), and several foreign governments on management, organizational development, operations and maintenance practices, and strategy. Seth has extensive knowledge of performance management techniques, advanced operations and maintenance practices, and change management frameworks.

Seth has a history of seeking challenging assignments where he can apply his extensive public sector experience and multi-disciplinary education in management, economics, and engineering to complex problems. He began his career as a regulator, leading implementation of the complex and enormously expensive Surface Water Treatment Rule as part of the Safe Drinking Water Act amendment of 1986 for the State of Maine. He became the General Manager of a failing New England utility that was teetering on the edge of financial insolvency at the age of 24. He turned the organization around and into an award-winning organization. Seth has worked internationally, helping the governments of Afghanistan, Jordan, Guam, Mozambique, and the U.S. implement management practices and environmental policy at the national level, while simultaneously assisting various development agencies with the implementation of more than $500 million in infrastructure and programmatic spending. In addition, he has assisted well-known utility organizations in the U.S. like Pittsburgh Water and Sewer Authority, Metro Water Services (Nashville), Boston Water and Sewer Commission, New York City DEP, Denver Water, Philadelphia Water, North Texas Municipal Water District, and PRASA (Puerto Rico) solve complex management and infrastructure strategic challenges.

Seth is the Past Chair of AWWA’s Strategic Management Practices Committee, which recently rewrote AWWA’s M5 Utility Management Manual − the industry guide for utility management practices. He participates bi-annually on producing AWWA’s Benchmarking Performance Indicators for Water and Wastewater as Vice Chair of the Benchmarking Advisory Committee.
