Green Stormwater Infrastructure Use to Control Combined Sewer Overflows

Utah State University Learn at Lunch Webinar:

Combined sewer overflows (CSOs) are a primary cause of environmental degradation in the nearshore environments of Puget Sound in Washington State. The use of green stormwater infrastructure (GSI) techniques to reduce or eliminate peak flow volumes in collection systems has shown promise in many parts of the U.S. This presentation will outline the process King County underwent to gain regulatory approval for a facility plan controlling CSOs in one of its combined basins, and how the county determined that GSI could be implemented as the control method.

John has worked for the King County Wastewater Treatment Division for 18 years. He is currently the combined sewer overflow program manager. Over the last nine years he has worked on the Combined Sewer Overflow Control Program and is currently managing the program and implementation of the Long Term Control Plan. John has developed and is managing the Green Stormwater Infrastructure (GSI) and Climate Change Adaptation programs. His climate work has been referenced in both the IPCC and National Climate Assessment reports. He is President of the Pacific Northwest Clean Water Association (PNCWA). He serves on sustainability and climate action teams at King County. John has a Bachelor of Science Degree in Environmental Science from Oregon State University and served six years as a sonar man in the U.S. Navy on-board nuclear submarines.
