Rainwater Harvesting: Guidance for Homeowners

By: Bill Hunt, Matthew Jones Urban Waterways

A rainwater harvesting system captures stormwater runoff, often from a rooftop, and stores the water in a cistern for later use. In this guide for homeowners, the authors describe the components of a rainwater harvesting system and how they work together. Guidelines for choosing, sizing and installing the components are included.

Stormwater Wetland Construction Guidance

By: Mike Burchell, Bill Hunt, Kris Bass, Jason Wright Urban Waterways

Stormwater wetlands perform well in reducing peak flows and pollutant removal when properly designed and constructed. These wetland construction guidelines are based on experience gained at more than 30 sites across North Carolina.

Choosing a Pump for Rainwater Harvesting

By: Bill Hunt, Matthew Jones Urban Waterways

A pump for the cistern or tank of a water-harvesting system can increase the system's uses significantly. In this publication get step-by-step guidance on how to choose a pump to best suit the system.

Permeable Pavements, Green Roofs and Cisterns

By: Bill Hunt, Laura Szpir Urban Waterways

This publication describes structural stormwater practices that filter and reduce stormwater runoff from residential and commercial developments: permeable pavements, green roofs and cisterns. The practices described can be used in low-impact development to conserve a site's natural response to rainfall.

Maintenance of Stormwater Wetlands and Wet Ponds

By: Bill Hunt, Bill Lord Urban Waterways

This publication presents maintenance guidelines for stormwater wetlands and wet ponds, two stormwater practices that are being constructed across North Carolina. Stormwater management practices must be kept in proper working order to maintain their intended functions and aesthetic appeal.

Bioretention Performance, Design, Construction, and Maintenance

By: Bill Hunt, Bill Lord Urban Waterways

This guide provides a review of recent bioretention research and its impact on design, construction, and maintenance of bioretention stormwater systems.

Stormwater Wetland Design Update: Zones, Vegetation, Soil, and Outlet Guidance

By: Bill Hunt, Jason Wright, Mike Burchell, Kris Bass Urban Waterways

These new design guidelines for stormwater wetlands focus on four design points: internal wetland zones, herbaceous plants that thrive in stormwater wetlands, a proper growing medium, and the importance of a flexible outlet structure and its construction.

Water Quality of Rooftop Runoff: Implications for Residential Water Harvesting Systems

By: Kathy DeBusk, Bill Hunt, Deanna Osmond, Greg Cope Urban Waterways

This publication discusses the presence of various pollutants in rooftop runoff and establishes some general guidelines regarding the use of collected rainwater in North Carolina.

Designing Stormwater Wetlands for Small Watersheds

By: Bill Hunt, Barbara Doll Urban Waterways

This publication focuses on stormwater wetlands: their function, effectiveness, design,advantages and liabilities and costs.

Mosquito Control for Stormwater Facilities

By: Bill Hunt, Charles Apperson, Bill Lord Urban Waterways

This factsheet provides a review of strategies for designing and maintaining stormwater facilities to limit mosquito populations.

Stormwater Wetlands and Ecosystem Services

By: Bill Hunt, Tricia Lynn Moore Urban Waterways

This design bulletin for stormwater wetland designers and managers introduces the concept of ecosystem services, reviews how stormwater wetlands provide many of these services and describes how wetland design can enhance ecosystem services.

Improving Exfiltration from BMPs: Research and Recommendations

By: Bill Hunt, Robert Brown Urban Waterways

In this publication, we summarize the current research and describe construction methods that developers can use to more effectively meet the goals of low impact development and stormwater management.

Removal of Pathogens in Stormwater

By: Jon Hathaway, Bill Hunt Urban Waterways

Controlling pathogens in runoff presents a growing challenge for stormwater managers and designers. This fact sheet provides an overview of pathogens: what they are, how they affect people, and how they are regulated; describes their association with stormwater runoff; and investigates stormwater management practices that may limit pathogen presence in surface waters.
