About the Workshops

Rainwater Harvesting Workshop

This workshop will provide fundamental background information on the easy-to-use NCSU Rainwater Harvester model. Additional information regarding innovative design modifications (i.e. passive and active release mechanisms) and research conducted in North Carolina will be provided. Demonstrations of the model will be given, and attendees will learn how to use the tool to design rainwater harvesting systems that meet the Minimum Design Criteria (MDC) needed to achieve stormwater management. It is strongly encouraged attendees bring an excel-friendly laptop to the workshop.

Instructors: Dr. Bill Hunt, Sarah Waickowski, Mitch Woodward, and Kathy Gee

Stormwater Nitrogen and Phosphorus Tool Workshop

This workshop will provide fundamental background information on the easy-to-use NCSU HyPerTool (bioretention) and PermPave HyPerMod (permeable pavement) computer models as well as the NCDEQ Stormwater Nitrogen and Phosphorus (SNAP) Version 4 tool. Attendees will learn how to use the tools to design stormwater control measures (SCMs) to meet nutrient regulations, estimate nutrient runoff from sites with and without SCMs, and evaluate development and stormwater treatment alternatives. Demonstrations of the models will be given, and attendees will also participate in hands-on design exercises. It is strongly encouraged attendees bring an excel-friendly laptop to the workshop.

Instructors: Dr. Bill Hunt, Sarah Waickowski, and Trish D’Arconte

Our Instructors

William F. Hunt, III, Ph.D., P.E.

Dr. Hunt is a Professor and Extension Specialist in North Carolina State University’s Department of Biological and Agricultural Engineering. Dr. Hunt holds degrees in Civil Engineering (NCSU, B.S.), Economics (NCSU, B.S.), Biological and Agricultural Engineering (NCSU, M.S.) and Agricultural and Biological Engineering, (Penn State, Ph.D.). He is a registered PE in North Carolina.

Since 2000, Hunt has assisted with the design, installation, and/or monitoring of over 90 stormwater best management practices (BMPs), including bioretention, stormwater wetlands, innovative wet ponds, green roofs, permeable pavement, water harvesting/cistern systems and level spreaders. He teaches 20-25 short courses and workshops each year on stormwater BMP design, function, and maintenance throughout North Carolina and the US.


Sarah Waickowski, PE, EI

Sarah Waickowski grew up in the great town of Fellsmere, FL and attended the University of Florida. She earned her B.S. in Civil Engineering with a specialization in Water Resources in December 2012. Her interest in stormwater grew after competing in the Florida Water Environment Association (FWEA) Student Design competition. She helped to treat runoff from a bridge by designing the conveyance network and identifying the site’s hydrologic characteristics. Sarah moved to Raleigh, NC and joined the Stormwater Engineering Group after completing her second internship with Duke Energy Progress at their Brunswick Nuclear Power Plant. She is pursuing her M.S. in Biological and Agricultural Engineering under the direction of Dr. Bill Hunt. At NC State, Sarah’s research will focus on gross solids, or large particles, collected in catch basins throughout various municipalities in the Piedmont and Coastal regions.


 Trish D’Arconte

Trish D’Arconte is an Environmental Program Consultant for the NC Dept. of Environmental Quality’s Nonpoint Source Planning Branch.  She has worked on water quality issues for over 20 years between the US Geological Survey, the Town of Chapel Hill, and DEQ.  She has extensive experience with stormwater and nutrient issues through her time with the Town and from serving on the State’s Nutrient Scientific Advisory Board.  Her current work implements the various State Nutrient Management Strategies including Jordan, Falls, Neuse, and Tar-Pamlico.
