Optimizing Stormwater Treatment Practices: A Handbook of Assessment and Maintenanceprovides the information necessary for developing and operating an effective maintenance program for stormwater treatment. The book offers instructions on how to measure the level of performance of stormwater treatment practices directly and bases proposed maintenance schedules on actual performance and historical maintenance efforts and costs. The inspection methods, which are proven in the field and have been implemented successfully, are necessary as regulatory agencies are demanding evaluations of the performance of stormwater treatment practices. The authors have developed a three-tiered approach that offers readers a standard protocol for how to determine the effectiveness of stormwater treatment practices currently in place.

Andrew Erickson is a registered professional engineer in the State of Minnesota and research fellow at St. Anthony Falls Laboratory working on projects related to assessment and maintenance of stormwater treatment practices, developing of new stormwater treatment technologies, and modeling stormwater treatment practices.

Peter Weiss is a Professor of Civil Engineering at Valparaiso University and a registered professional engineer in the state of Indiana. His research interests include the construction and maintenance costs of stormwater treatment practices and optimizing stormwater treatment practice performance. He has acted as a consultant for the City of Valparaiso, Indiana to assess the performance of stormwater management practices within the city.

John Gulliver is a Professor of Civil Engineering at the University of Minnesota and a registered professional engineer. He has run a successful stormwater treatment research program in collaboration with colleagues for over 10 years.
