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.
This course introduces the basic principles 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 consideration of the use of rainwater harvesting systems.
This course is based on the publication, Texas Manual on Rainwater Harvesting.
The information in this course may be useful in planning and sizing of rainwater harvesting systems.
This course includes a multiple choice quiz at the end which is intended to provide 8 hours of professional development.
