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.

I bought the rain harvest rain barrel collection that connects to your rain gutter downspouts. It works so good that I bought a second barrel for the other side of my house. Connect a hose to the spout at the bottom and you have free water. Great for drought areas like Southern California. I would recommend this company and specific product to anyone.

Item as advertised. Shipping was at the top limit of what I would pay.

I installed the Ultra downspout filter system about 3 yrs ago and had adequate results for about a year. Then the fiber washers wore out. I replaced them several times over the last 2 years, but never got the same performance. I scraped the whole system this summer and replaced it with the First Flush Diverter and Leaf Eater system. The results are much better, with a few modifications. First I scraped the drain and filter basket completely and replaced it with a 2"pvc T threaded into the bottom of a 55 gal plastic drum with a bulkhead fitting. The bottom being a threaded 2" clean out and the side fitted with a hose bib to use the water in the flower beds. The ball diverter is installed on the top of the drum with a 2" bulkhead fitting. Above the diverter is a 3" pvc connected to the leaf catcher. This modified system has increased my capture rate significantly.
