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.
Although one of the most common stormwater control measures for managing roadway runoff, increased demand for urban stormwater control has resulted in the evolution of swale types. This publication proposes standard definitions for swale terminology for consistent application across communities.
This publication discusses ways in which mosquitoes could become a problem for rainwater harvesting systems and provides solutions and preventative measures to protect cisterns, rain barrels, and other rainwater collection systems from becoming havens for mosquitoes.
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.
This factsheet provides a review of strategies for designing and maintaining stormwater facilities to limit mosquito populations.
An innovative Dune Infiltration System (DIS) has been developed to help prevent polluted stormwater from reaching the ocean. The goal of this factsheet is to introduce this technology to coastal towns that want to reduce the potential impact of stormwater discharge to their beaches.
This publication provides plant recommendations for infiltrating wet ponds constructed in areas with sandy soils. Plants in these areas must be able to withstand periods of both drought and inundation due to the nature of the soils.
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.
This factsheet is designed to give a brief overview of natural and constructed wetlands and provide key information to help identify these wetlands and the functions they provide.
This guide provides a review of recent bioretention research and its impact on design, construction, and maintenance of bioretention stormwater systems.
Golf courses provide a unique setting for wetlands that can be used to provide both an environmental benefit and an aesthetic amenity. The research-based recommendations in this publication are intended to help you optimize concepts and designs for your next project.
As the use of permeable pavement increases in North Carolina, practitioners can look to research findings for guidance. Recent research in North Carolina and elsewhere has focused on four aspects: runoff reduction, clogging, long-term hydrology and water quality. This overview highlights research findings, discusses research implications, and provides direct links to the research.
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.
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.
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.
This question and answer worksheet will help coastal homeowners focus on potential problems with the pollution and health risks of water protection practices and the effects on water sources from stormwater management. Car/truck wastes, yard/garden wastes, animal wastes, rain gardens and rainwater runoff are covered.
