What Is Rainwater Harvesting?

Rainwater harvesting is the process of collecting water during rainfall and storing it for various future uses. Such uses could include for watering plants and maintaining gardens, drinking water for livestock, irrigation for agriculture, even drinking water for yourself.


The systems for catching rainwater can be as simple as a barrel catchment to as complex as large scale commercial systems like BRAE for businesses and schools depending on what the water is being reused for.

Benefits Of Rainwater Harvesting

Confused about why you would want to harvest rainwater? Ask Tom Brady. He and Giselse Bundchen built an eco-friendly mansion in L.A. They had a rainwater catchment system installed to reduce their water consumption.

Because rainwater is the purest form of water it really just makes the most sense to keep it – especially if you live in the Pacific Northwest where we might tend to take water for granted. Collecting your own rainwater cuts down on your dependence on the filtration process not to mention your overall water consumption. With this self-sufficiency you can now safely water your yard and plants because rainwater is non-chlorinated. An extra special benefit is the cost-effectiveness and savings of catching your own rainwater and reusing it.
