Stand Alone Rainwater Harvesting System
by RainSaucers Inc. on November 7th, 2016

Two of our products (the 48" and 84" RainSaucer) are designed to work only with 2" NPS standard holes.  If you're lucky, your 55 gallon drum or 270 gallon IBC Tote already has one built in. If not, you can always add one with a 2" Bulkhead Fitting.

If you have a removable lid, bulkhead installation is easy. Just drill a a 3" or 3 1/8" hole in the lid (or cap), insert the Body and Sealing washer (see photo) from one side and screw on the Friction washer and Nut from the other side and you are done.

If you don't have a removable lid, you have to find a creative way to keep one half of the fitting in place underneath while you screw in everything else on the other side. For completely closed gallon drums this near impossible so we usually recommend switching to a 2" UniSeal with a 2" Pipe and 2"Female Adapter installed (for the 48" only). For other types of closed tanks, we recommend using the manhole cover to reach your hand inside and hold half of the bulkhead fitting in place while the other half gets screwed on.

One problem specific to the 48" RainSaucer is that heavy wind gusts (considered gale force according to the Beaufort Scale of Wind Force) can sometimes warp or invert the unit making it unusable. In our experience, this is only a temporary issue. Once this problem occurs, the key is to reinstall the system by:
  • removing the fasteners
  • laying the disk out until it becomes as flat as possible again (with weight if needed)
  • reinstalling the unit
We like to think of it as a reboot which you should expect to perform a few times per season as part of normal maintenance.  If the problem occurs more frequently, it means the winds in your area are regularly above the rating we have given for the product (30MPH) and you should consider an upgrade to our more wind stable 59" version (rated for 50MPH).

An alternative to upgrading is to implement the 48" directly on to an open container such as a trash can (as we do with the 59") and running two perpendicular ropes from holes on one edge of the unit, under the container,  to holes on the opposite edge on the RainSaucer.

If you don't want to switch tanks or containers you could also host the 48" RainSaucer on a 5 gallon bucket instead and put the new implementation on top of your original tank. Then all one needs to do is make an overflow  from the bucket to the tank.

The hardest thing about being a small company is how inexplicably long things take. We first had the idea for a balcony based rainwater harvesting system 4 years ago. We already had customers collecting rainwater on building rooftops so balconies seemed like the next logical transition. So three years ago we started prototyping and in 2014 we even sent a unit out for a customer to test. But it took us another painstaking  2 years until today when we can finally say to customers "we are ready to ship." Most of the delay came from making sure the product is  easy to use yet as sturdy as possible. Now we think we have the solution that's just right for your typical urban balcony garden. All the details about the product are here. Please feel free to contact us with questions.

Unless it rains year round in your area, you will most likely have a Season when you will not be collecting rain. For those on the West Coast, that Season is Summer (no rain just 5 months of Drought). In the Northern regions of the Midwest and East, that Season is Winter (our products are not rated for snow). During those off-Seasons, we highly recommend you store away your RainSaucer to increase its longevity. Fortunately, take down is easy and there are multiple ways to store the RainSaucers disks.
  • Hanging on the wall: in our experience, the holes at the outer edges are strong enough to support several months of placement on a hook or nail. Wall hanging is also a nice space saver.
  • Standing upright between wall and rack: the disks are thin enough that they can easily slide between the wall and a storage rack in the garage. The key is to make sure the fit is tight so that there is no buckling at the bottom.
  • Roll up and store in a rain barrel (see photo):  if you’re storing your RainSaucer and rain barrel both, why not put one inside the other? The RainSaucer disks can be rolled into a cylinder and dropped into your open top barrel, drum or container.
Finally, if you are the proud owner of an 84” RainSaucer, you only need to store the white fabric sheet. The remaining metal parts are made from galvanized steel and should have no trouble weathering the off-Season.

What's the biggest marketing headache for vendors in the rain barrel and rainwater harvesting industry? Lack of awareness and the persistent myth that catching rain is illegal, especially in the West.

We got  so tired of proving the legality of RWH back in 2013 we wrote a now widely read post on the topic. In that original post we talked about Colorado's pilot rain barrel programs and local efforts. But for many Colorado residents that wasn't enough- they wanted a State bill that would fully sanction rain barrels. The result:  as of April, 2016 Colorado is now a fully rain barrel friendly State. Gov. John Hickenlooper signed House Bill 1005, which allows a maximum of two rain barrels — with a combined capacity of 110 gallons — at each household. The measure is to take effect on Aug. 10. The Colorado Legislature passed the bill  after previously rejecting the measure in past sessions over concerns that household rain barrels would take water from the supply available to agriculture and other water-rights holders.

With Colorado's embrace of household rainwater collection, there is no place left in the United States where legality could be in question. Time to put that myth to rest once and for all.

Some people simply prefer to build things themselves rather than buy off-the-shelf products. We get that. In fact, many of our Prepper and Gardener customers are natural DIY types that view rain catchment as the DIY alternative to piped city water. And yet these customers still come to us for the rain collector portion of their projects. Why? Because as simple as RainSaucers are they are not easy to replicate with store bought materials. The UV resistant plastic we use in the 48" and 59" versions can only be bought wholesale.  Similarly, the base plate we use in the 84" version is a custom job. Still we often get comments on our Social Media posts that our product's functionality can be replicated by other means.

The main DIY competitor we hear about is the upside down umbrella on a bucket. We know this concept well because it's where we started. Our first prototypes were upside down umbrellas. But we gave up on that approach because the umbrellas never lasted. The material always ripped, the rod always rusted, and inversion from wind was a problem. Another DIY competitor we hear about is the Boy Scout Tarp method. Again we know the method well as it was the inspiration behind our 84" version. The 84" version fixes the problems associated with the Boy Scout method- namely that normal tarps rip from wind (we use extra heavy weight material) and you can only use it if you have trees as a an anchor. The water inlet on the 84" is also extremely efficient whereas the Boy Scout method usually has a problem with loss of rain catchment.

A full rain barrel is a great thing.  But it also means you are now catching and then losing precious rainwater. Or worse, you could be creating a home for mosquitoes.  That's why almost every rain barrel needs an overflow hole.  Simple ones are nothing more than a  hole in the side of the barrel (toward the top) that are covered with some glued on mesh screen. More sophisticated ones allow you to send that overflow into an adjacent barrel so as not lose any rain.

But adding more water storage can be tricky- namely how do you get that overflow from one rain barrel to another? Over the years we've learned that the easiest solution is to drill a hole in the side of the barrel (toward the top) and install a grommet that hugs the hole while allowing a pipe to be added. The brand name of the grommet we use is called Uniseal.

Uniseals come in a variety of sizes but for rain barrel overflow, it does not have to be big. Once a Uniseal is installed and the pipe added (see picture) you now have a means of taking  overflow from one barrel to another.  This can happen at the top inlet of the second barrel (assuming the second barrel is shorter that the first) or at the same height into an appropriately sized hole in the second barrel (the hole should have space for the pipe only).

We would be remiss if we didn't mention that one alternative to an overflow hole is to daisy chain the bottom holes of the rain barrels.  This allows for simultaneous fill up of two barrels. This article describes how one can do that.

With a little creativity, a RainSaucer can be made to work with just about any rain barrel. As long as the lid is removable, a bulkhead fitting will get you the 2" hole you need to install the 48" and 84" sizes.  If the lid is removable and completely circular then a 59" unit can also be applied. However, if the lid is not removable, then the barrel must have a 2" NPS hole. If not, the only solution at that point is to install the RainSaucer in a different tank and daisy chain the bottom holes of the tanks together. Below is an example. Instead of daisy chaining, one can also do a simple overflow from one tank to the next.
Regarding specific brand name rain barrels on the market, below are a few specific examples of how our customers have implemented RainSaucers...

59" with Earthminded RainStation

48" with Bushman Tank

48" with Moby

Finally, if you haven't purchased a rain barrel but are looking to buy one that it compatible we recommend the following:

For the 48" and 84": buy a closed 55 gallon drum or 270 gallon IBC Tote on Craig's list and use our DIY Kit to make your own rain barrel. When you buy, make sure the drum/tank has a standard 2" NPS holes. Or bring your RainSaucer part kit with you when you buy, and try the adapter. If it threads in, you're good. Costco and Sam's Club sell 55 gallon drums in new condition.
For the 59": buy a BRUTE or Roughneck trash can at your local hardware store and again, use our DIY Kit to make your own rain barrel.

We've been working on the global clean drinking water problem for 5 years now. In 2011 we launched our flagship product and immediately went down to Guatemala to see if our 48" RainSaucer could be the ultimate solution (see video). It was well received but the general consensus was the price needed to be lower for folks at the Bottom of the Pyramid. We also came to understand that without a cheap form of water storage, our efforts would be wasted because the total system cost would still be too high. So in 2014 we took another look at the problem and thought we might be able to do something at the $2 cost level. We had some initial prototype success with our cardboard "Two Dollar Tank" but in the end we just couldn't make it last more than one season. Yet we are not the kind of people to give up. And now we have a new concept: the $6 Cistern.

The Six Dollar Cistern is a 150 gallon tank that both catches and stores rain water. The Cistern has two components: a ruggedized phthalate free 5' wide vinyl pool that costs $3 and a food-safe HDPE cover that can be made for $3. The pool cover has a filtered inlet for preventing debris from entering the tank and an outlet for pumping or scooping of water. The Cistern can be deployed either as a stand alone rain collector or as general purpose water storage. The main target is families at the Bottom of the Pyramid. The $6 cost means a final retail price of $10- putting it well in the reach of families earning $1-$2 per day. In countries where such families buy bottled water, the investment would pay for itself in less than one rainy season. In other places, the investment would pay for itself in terms of the productivity  gained from improved health and reduced time searching for water.

As a stand alone rain collector the Cistern will catch 12 gallons per inch of rain. So for example, in Guatemala where it averages 30 inches of rain per year the Cistern will catch 360 gallons, enough drinking water for a family of four for most of the year. Since the pool is inflatable and the cover can folded, it can ship in a box as small as 1/2 cubic foot enabling easy packing, shipping, and distribution worldwide.  The first prototype was tested in the Summer of 2015 and was fully functional.

We believe that ultra-low cost, portable water storage would not only spark a boom in rainwater harvesting worldwide but that it would also have applications for disaster relief. In the event of an earthquake or tsunami, inflatable rainwater harvesting tanks could be deployed by NGOs on the ground to store initial supplies of water that would replenish themselves with rain. Future iterations of the Six Dollar Cistern could also be targeted at small plot farmers as a water storage source for drip irrigation.

We've got great customers that appreciate us enough to send pictures and comments for the Communities' benefit. At the beginning of the Year we post the most interesting ones from the previous Year not just for the Community but for us, as a review of our progress. Looking at these pictures you can see 2015 was good to us:
  • our new 84" version finally started to gain traction.
  • a few of our systems started operating in Africa.
  • use of the product was widespread from Maine down to Florida back up Canada across North America to Texas and California.




Customer in Texas uses a RainSaucer to provide much needed water to wildlife in his pasture. The system collects water and dispenses it automatically.


Customer in Florida writes "I love the Rain Saucer. It's a great product for my garden! My terrace is on the 5th floor and faces the ocean. I get get really strong winds when it rains, so I made an adjustment by tilting the front of the saucer so it will not blow over. Works great! See my attached photo. I am buying a back up! "




Customer in Maine using our system to water cacti automatically with drip lines. He calls the RainSaucer "one of those incredibly effective devices that is so simple it makes me wonder why someone didn't think of it a thousand years ago!"






Rooftop rainwater collection for a Community Garden sponsored by City of Madison Water Utility








Students in PA got an IBC Tote from the local water utility and installed a 48" RainSaucer to demonstrate water sustainability.


Finally made it to Africa, to Rwanda, thanks to NGO Manos de Madres These women run a market garden cooperative that has had difficulties purchasing water. The RainSaucers are expected to decrease that dependency.
Patio at Dunkin' Donuts in Tampa, FL. RainSaucer catches the water which is automatically dripped to hanging veggies through use of solar pump. Food is donated to local shelters. Install by veteran owned The Urban Farming Company


Customer in Arkansas first to put an 84" RainSaucer on a 270 gallon IBC Tote. This setup is uphill from the home. She plans on feeding it to a small water tower near the garden for easy irrigation.
84" installation at Community Garden in Toronto. The main barrel overflows to the other two making 150 gallons in each cluster. There are 5 such clusters at their Garden.
This customer in Alabama installed a 48" RainSaucer into an EarthMinded Rainstation. She writes "I plan to use the water for my plants and if necessary during a crisis we can drink the water. I will also use the water for my animals drinking water so they can have chlorine free water...I didn't want to collect water from a rain gutter system off the roof. That water is not safe to drink so I don't want my vegetables using that water either. I don't have gutters so I didn't want the added expense or trouble of installing and cleaning them. I also like that I can put the rain barrel close to the location I will be using it. One is by the greenhouse. The other will be out by my garden. I hope to save money by collecting rain water. Thank you for the rainsaucer what a clever, common sense invention."







This Silicon Valley engineer was looking for a fast, DIY way to collect rainwater in a clean way. He told us he chose the BPA-free RainSaucer because of its simplicity and food safe surface.
The harvested rainwater will be used for growing fruits and vegetables in the garden.
