This week Steven got our catchment system hooked up. The 325 gallon tank is already over half full, after just 1/3 of an inch of rainfall. We are pretty excited!
The roof over our garage is flat, which is not great for much, but it does lend itself well to the easy collection of water. The water runs down the slight slope of the roof into the gutter, where it then flows into the downspout and through the Clean Rain Ultra. Steven did a lot of research before deciding on this device, and was ultimately swayed by it’s smart and simple design, which includes 4 features all in one relatively small package. After a “first flush,” which prevents accumulated contaminants from entering your tank, the water is then diverted into the storage tank. This divereter valve can also be adjusted manually. A fine stainless steel screen is included in the system to keep things like grit, fir needles and even mosquitoes out, so your tank doesn’t become a mosquito breeder; and a rain head keeps leaves and other larger debris out. When the tank is full, it is made to divert to a little pond down the hill. We still need to work out the details of how to get the water to the point of use, but that shouldn’t be too hard at this point.
It’s exciting to think how much water we will be able to save, and it makes us feel a little more ready in case of emergency. Essentially, we live in a rainforest. We receive an average of 80 inches of rain per year here – which, if the math whizzes did the math right, means about 4 gallons per hour, every hour, just from our garage roof! Steven is starting to research small scale hydro power, with the idea of creating some electricity with all the rainfall we get. It seems totally possible.
For now though, I am just hoping to be able to water the garden almost entirely with collected rainwater this summer. I think the plants will be happier with that too.

++ UPDATE (with an even more recent photo coming soon). This post gets so many hits, I thought it would be worth showing a slightly more updated version. The cedar surround is there partly to conceal the tank, but also to protect it from sun. Sunlight allows for unwanted bacterial and algal growth, and your water will turn green. The visible side here (south) was shortened to allow a roof to be put on. A wall was put up on the west side as well. A few adjustments were made to the piping to accommodate.
It’s so great that so many people are interested in harvesting rainwater!
5/19/14 UPDATE: A new post has been added on May 19, 2014 which includes more details on the system. It can be found here.
Very cool! I wish more people were so environmentally-minded. :)
Sound so exciting! Very clever. It’s always nice to see S’s projects with wood. {the link to Amazon has a part – linking to your blog – you may want to clear}
that looks like a good looking system. well done steven. and boy, you get a lot of rain!
Awesome!!! Very inspiring! I’ve been wanting to do some rain collection here to water our garden also. We are blessed to be in a place with an abundance of rain.
That is amazing. Well done!
Very inspiring indeed! I just finished watering my garden (which is small right now with lettuces and such) for the 3rd day in a row from my 40 gallon rain barrel. The rain barrel is empty now but it’s supposed to rain this afternoon. Your system will last so much longer. Hmmmmm…..
“average of 80 inches.” !!!!!! Shoot, my average annual precipitation is around 11.2 inches…Fresno, CA. :P
can you tell me where you got the 325 gallon containers and what they cost?
I was noticeing you can get used containers on the net some starting as low as 50 and going up from there some come with metal cages which would be good for those cold enviroments.The used ones I looked at just had liquied soap in it clean it out and its good to go for garden needs.
Micah, We got our container locally from a guy that was advertising on Craig’s List. They were food grade and had been used previously for storing some kind of sweetener.
Thank you for posting. Please keep us updated. I want info on the hydropower. I live in the Caribbean & I hate to see all that power run down the street! God bless.
Greaty article! Any chance we could see how he actually connected the spouting to where the water enters the container? A picture is worth a thousand words :-)

Where we live it is legal to capture rain water. That isn’t the case everywhere. We store the water we capture in two linked 55-gallon barrels and use it to water a garden where there is no other source. We don’t have a roof nearby so we use a large tarp suspended between trees and a large funnel into the top of one of the barrels. A piece of window screen keeps needles and large items from getting into the barrels to clog the hose at the bottom. http://powellriverbooks.blogspot.com/2010/04/double-barreled-watering.html – Margy
You should check with local codes. Many parts of the U.S. it’s illegal to store rainwater. Environmentalist. Diverting the natural flow of water and all that…

We live in Southern Indiana and have totally supplied our family with water collected from rain since 1981. We use it for everything. We have an underground water cistern that holds 5500 gallons of water. It is supplied with water from our gutters (with covers). The water travels through a 5 gallon bucket filled with rocks and a screen. That collects dirt and small particles that we clean out once a year, A water pump feeds the water to a pressure tank which sends water to the house. Works great! We have only had to buy a truck load of water a couple of times due to extreme and unusual (for now) drought. I am a bit concerned about
climate change reducing our supply but we could put in another cistern to catch the excess when it rains a lot. We have been drinking this water with no ill effects for 38 years.
Paint your tank black .it stops the bacteria growth.
