CE-001 A Guide to Rainwater Harvesting

A Guide to Rainwater Harvesting

This PDH online course is a part of the Civil course category. This course introduces the basics of residential and small-scale commercial rainwater harvesting systems design. It is intended to serve as a first step in considering options for constructing a rainwater harvesting system or implementing a harvesting program.

Rainwater is valued for its purity and softness. It has a nearly neutral pH, and is free from disinfection by-products, salts, minerals, and other natural and man-made contaminants. Plants thrive under irrigation with stored rainwater. Appliances last longer when free from the corrosive or scale effects of hard water. Users with potable systems prefer the superior taste and cleansing properties of rainwater.

This course is intended for use by civil, environmental mechanical engineers, sustainability design and construction professionals and others interested in learning about the best management practices for rainwater harvesting.
