The basic concept of rainwater harvesting is to catch the water falling from the sky and use it with more direct purpose and before it gets dirtier from the ground. Section 1.2 covers the main types of systems, Section 2 covers the components of a rainwater harvesting system, Section 3 covers gravity and pressure, and Section 4 dives into the calculations for sizing various aspects of a rainwater harvesting system.
Section 5 describes community engagements that built the types of systems covered in this book while Section 5.7 covers some organizations implementing this knowledge. The background and history of rainwater harvesting are rich and out of the scope of this book. If you are interested in learning more, please see the resources in Section 6. Finally, Section 7 contains problem sets to test your knowledge and prepare you for designing your own unique system.
