After a very successful Kickstarter, To Catch the Rain, is now available to all. This book is for practitioners, DIYers, and community members looking for water solutions, as well as for students and teachers in environmental science, environmental studies, sustainable design, international development, engineering, and mathematics.

Read stories of implementing rainwater from Mexico, the US, and Dominican Republic through effective collaborations with inspiring community organizations such as Otros Mundos Chiapas and Colectivo Revark.

Get the book at local bookstores or on Amazon!

Or get the free digital version by signing up.


Get exclusive diagrams, images, and extra-resources, such as this diagram describing how the first flush gets rid of the first, and dirtiest, part of the rain before using or storing it.


Explore math that allows for sizing systems, gutters, tanks, and more. The true examples and possibilities become a context for learning. Problem sets at the back of the book are applicable to students from middle school through college, and non-students as well. Teacher resources are also available upon request, such as solutions and spreadsheets.
