Rainwater harvesting is an ancient technique enjoying a revival in popularity due to the inherent quality of rainwater and interest in reducing consumption of treated water. Rainwater collection has numerous benefits such as: free supply, low mineral and sodium content, reduction in non-point source pollution, and reduced demand on water utilities.
The scope of this course is to serve as a primer in the basics of residential and small-scale commercial rainwater harvesting systems design. The design process includes choosing system components in the most cost effective and advantageous manner. It is intended to serve as a first step in thinking about options for implementing rainwater harvesting systems, as well as advantages and constraints.
