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 heated by pavement and rooftop materials can affect aquatic ecosystems in streams, especially coldwater trout streams, because of high temperatures. This web only publication describes recent research on stormwater BMPs near coldwater streams and recommends design modifications that can be applied to stormwater wetlands, wet ponds and bioretention areas to moderate stormwater runoff temperature.
