How to Build The Ultimate Rain Catchment System

September 4, 2015

Rainwater Harvesting

I recently published a report on how to build “The Ultimate Rain Catchment System”… a system that uses 7 mechanical levels of filtration to purify water off of any roof.

Plus…

Can be used to pipe hot water into your home, without using any electricity.

And that report has been SO popular that I thought you might like a more up close and personal VIDEO tour of what a truly awesome rain catchment system should look like.

So Scott Hunt, the guy who designed the blueprints for The Ultimate Rain Catchment System, was kind enough to shoot this video, so you could get a closer look at some of the cooler working parts of this system.

Because if you’re going to build a Rain Catchment System, this is the BEST way I’ve ever seen to do it!

Enjoy!

    Considering that it runs on electricity, has several filters and parts that might need replacing….seems like a still for distilling the water might be more sustainable. Distilling the water would definitely make it just as safe to drink and in the long run, be cheaper and less complicated. Just a thought. Thank you.

      So you know Lora… he has one of those too 😉

      And as for the electricity, he has both electricity that is running off of two solar pannels, and he also has a manual pump that you can see on the outside of the building that can give his house pressurized water for 10 minutes. And he has wood fired methods for heating his water tank too.

      So while he didn’t mention them in this video he does have all those things.

      Unless you have a lot of trees on your property for firewood, distillation isn’t a cheaper solution, Takes a few hours of burning wood or fuel to get a gallon of distilled water. If distillation were cheap then places like California would have all the water it needed.

    Wow! I’m pretty left brain and OCD. This really is exactly what I want to see! Fantastic! Can’t say enough good things about this video.
    Now ask him to do some studies on rocket stoves. The ones online are just way too steeped in “mud pie technology” for those of us who lean toward engineering!

    Put yes for the club, but don’t know if it went connected.

    Do you have an approximate cost for the system?

    Hey 775,
    Thanks for such good posts with a technical aspect. Very enjoyable and doable. I have a rain collection sys but just for the garden. I devised what I thought was a foolproof 110 gal fresh (municipal) water sys.
    I simply interrupted my house water running it into two 55 gal plastic barrels like a water heater. Every time a house facuet is turned on fresh water flows through the barrels maintaining fresh water. I’m having trouble with the pressure (60 psi) which burst one barrel during testing. I may need to find higher psi barrels, maybe metal. The plastic with the bung holes seemed perfect.
    Do you know of anyone who has done anything like this?

    how long are the filters good for?

      That depends on how clean the water is to start with. Unless it has extremely high levels of contaminants that the filter removes you can safely use them for twice the rated gallons/litters (probably more but, only if you can test for the contaminants or know your water has very low levels of contaminants)

    What about chemical residues? Roof materials can give off chemicals for years. Without some method of purification beyond what is demonstrated here, one would need to make sure to use a potable water roof material. Definitely not asphalt or fiberglass, but even concrete can have issues. The best bet would be metal, anodized or painted with a safe material for potable water. This has been the on-going challenge to using rainwater catchment for drinking water. And distillation doesn’t work with all VOCs due to the boiling point of some of them.

    David that’s the reason for diverting the first of the runoff before saving any water. Very little leaching occurs during most rain events. It washes off what leached between events. Yes, doing what you can to minimize contamination before it rains is good, as any failure of filter will cause less harm and the less filtering needed the better. Just because there are no popular filters that do a good job of removing VOCs, it is wrong to think there are none that can. But of course the real issue is having enough filters on hand to handle your filtering needs, if they become unavailable. So any homemade filter that can reduce the load on your commercially manufactured filters is good.
