Abstract

Water scarcity, population growth, and climate change have driven increased interest in the use of stormwater and graywater as a means to diversify water supply portfolios. This project convened a committee of knowledge experts to conduct a study on the risks, costs, and benefits of on-site water reuse of stormwater and graywater. The study also investigated safety and regulations related to treatment and storage of stormwater capture and graywater reuse for various end uses.

The "Report in Brief," a four-page summary of findings, is posted below under Project Papers. The full report can be downloaded for free on the National Academies Press website.
