Design Spec
Design Spec: Rainwater Harvesting, 2013
Developed by the Virginia Department of Conservation and Recreation, this design specification (Version 2.2, 2013) provides guidance on capturing, storing, and reusing rooftop runoff through rainwater harvesting systems such as cisterns. It helps designers size systems based on water supply and demand, integrate non-potable reuse applications, and maximize runoff reduction and water conservation benefits.
