Literature Review

This page describes some of the basics behind designing Rainwater Catchment Systems. It is a collection of resources pulled from similar projects that are documented throughout Appropedia, and contains helpful resources for those interested in learning more.

Rainwater Catchment

A rainwater catchment system is a system that collects, filters, and stores rainwater for community or household use. [1]

Rainfall

One of the first steps to designing a Rainwater Catchment system is to determine the amount of rainfall that will fall in the desired location. A good practice is to determine the average precipitation depth in inches for each month. This data can typically be found from sources such as the PF Data Server from NOAHH,

Catchment Potential

Besides the amount of rainfall that is available to be collected, the size of the collection surface will determine how much of the available rainfall will be collected for usage. Sites such as the Rainwater Collection Calculator can aide the design process.

Roofing

The type of construction material is important for a rainwater catchment system. Depending on what material is used for the roof, the collected water can be contaminated by carcinogens[1]. The roofing materials used in a rainwater catchment system should be chemically inert to keep contaminants out of the system. In addition to the roof material itself, the climate can influence the contaminate runoff depending on the material.

Types of Roofing Material

The following are brief descriptions of a few common roofing materials and their benefits and drawbacks when being considered for Rainwater Catchment Projects.

Water Quality

Filtration

Gutters, Pipes, and Downspouts

First Flush

Storage
