Harvesting rain is a practice that has been around for centuries. Cisterns and other rain harvesting systems are widely used in Europe, Australia, India, the Bahamas and countless remote countries - many who depend solely on rain for day to day life.When water supply becomes limited, practical solutions can fill the gap. Rainwater harvesting systems provide distributed stormwater runoff containment while simultaneously storing water which can be used for irrigation, flushing toilets, washing clothes, washing cars, pressure washing,or it can be purified for use as everyday drinking water. You can really take this as far as you want. But it all comes down to various filtration and processing systems.Explore: Let us guide you through the entire process.Understand: With our rainharvest lab it becomes easy for you to envision a rainharvest system of your own.Collect: There is more rain coming, catch it.

Ordered some replacement parts for my 7 year old rain barrels on a Sunday and I got it on Tuesday. The connecting tube is a much better tube than the I was using that came with the diverters 7 years ago. I love harvesting rain water and releasing it on demand.

I ordered a Graf Carat complete Rain harvest system 1000 gallon. Im very pleased of the quick response to help me make the best decision. While installing the system, i was pleasantly surprised about the quality of the products and how easy it was to install. The tank is made in Germany and very easy to assemble and handle! Thank you very much for this nice system!

I purchased a Viqua UVMAX Pro20 Series 20 GPM UV Disinfection System. The lamp failed after 7 months. I called Viqua for replacement. Viqua told me to contact RainHarvest - whom I bought it from. With RainHarvest's assistance I got the replacement UV lamp in about one week. It is probably a good idea to have a spare UV lamp around.

The book arrived in 3 days - unheard of in remote Alaska. The book is excellent. I am so glad I found it before I began making numerous mistakes. The photos and illustrations help to make the narrative that much more clear and concise. I'll eventually buy all 3 books for both myself and my children. It is worth every penny.

I've done 4+ orders with RainHarvest - everything has been great. Communication is excellent via both phone and email. I've had to cancel (in process) orders due to changes on my end and they've been happy to help. Products I've bought have been great...
