A Guide to Rainwater Harvesting
This online engineering PDH course introduces the basic principles of residential and small-scale commercial rainwater harvesting system 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. The information in this course may be useful in planning and sizing of rainwater harvesting systems.
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 6 PDH online course is intended for use by civil and environmental engineers, design professionals, construction personnel and others interested in learning about the best management practices for rainwater harvesting.
