Stand Alone Rainwater Harvesting System
by RainSaucers Inc. on September 20th, 2016

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.

Only a Walking Dead fan with a keen interest in Water technology would find this interesting. But to us, the way the survivors stay hydrated is the most educational part of the show. During the first few Seasons, when Rick Grimes and his group were either "on the run" or staying in temporary situations, the group was somewhat lucky. They were able to camp near streams or lakes, stay in houses where there was a well, or get liquids from abandoned cars, houses, and markets. But once they decided to settle down at that Prison in Season 3, things got decidedly more complicated. The Prison had no well.  With no local source of water, the team had to resort to the best alternative: rainwater harvesting. Since Season 3, we have seen rain barrels pop up two more times making it now worth commenting on. For the record (and let us know if we've missed something), here are the rainwater harvesting case studies from the Walking Dead:

Season 4 as the group settles in to the Prison

The group constructs a shelter in the courtyard of the Prison using corrugated metal sheets and wood beams. The shelter is used as shade from the Sun and as a place where they can cook and have outdoor meals. But the shelter is also lined with gutters that feed several strategically placed 55 gallon drums. As seen in the photo above, they elevate the drums by placing them on drums that have been cut in half. The harvested rainwater is dispensed into 5 gallon buckets and used for drinking, vegetable garden irrigation, and laundry.

Our comment: we see this set up all over the developing world. The corrugated metal sheets look pretty rusty but the water is probably still OK. However, three or four barrels won't be enough for the needs of the group later on when it grows in size.

Season 5 by the rival group at Grady Memorial Hospital

Isolated to the top floors of a Hospital Building, a group of police officers survive by growing food on the roof. They harvest rainwater from one section of the roof thanks to gutters that feed two IBC Totes that are mounted on cinder blocks.

Our comment: The IBC Totes are white, meaning that toxic algae will eventually develop unless they paint or cover the tanks. If the roof is asphalt, as is the case with most commercial buildings, the water will contain dangerous chemicals. This water is clearly non-potable although the 540 gallons is probably enough for the group's size.

Season 5 at the community of Alexandria

At her first interview with Rick Grimes, the Alexandria leader Deanna Monroe explains how the community was designed for sustainability. In addition to solar panels, "each home has a cistern", she says. Those cisterns turn out to be the 60 gallon Fiskars Salsa Rain Barrel systems you see at Home Depot. Such systems come with a diverter which has also been installed at the homes in Alexandria.

Our comment: when Deanna said "cisterns" we though she meant underground 5,000 gallon tanks plumbed back into the home for water use throughout the home. But she meant rain barrels which does not equate to that much water.  As discussed above, if the roofs are asphalt, the harvested water will have harmful chemicals. This "cistern" water is nothing we would want to drink "as-is".
In conclusion it would appear that none of these cases are perfect. But we give kudos to the producers for trying to bring a dose of realism to the show. Rainwater Harvesting is one of the best Survival techniques when other sources of water are difficult to obtain- as often happens when you are under siege by the Zombie horde.

It's one of the great virtues of doing business online- the ability to engage with customers around the world and see your product extend its global reach. The hard part, for us, is that not every country is in our serviceable range.  Our carrier USPS (the only one that takes our odd shaped parcels) has different size limits depending on the protocols agreed to with each country.  Even more frustrating is when those protocols appear arbitrary. For example, New Zealand accepts our packages but neighboring Australia does not. So for the record (we will keep this updated as USPS agreements change) here are the countries to where we can ship:
  • Any US territory including Puerto Rico, Guam and the US Virgin islands.
  • Canada*
  • Most countries in Europe*
  • Most countries in Asia*
  • New Zealand*
*Note: Customer is acting as importer and is responsible for all applicable import VAT and customs. Customer is responsible for keeping track of shipment (we provide tracking number) and contacting your local postal system should any additional payments be required. To process your shipment, we require a local address, phone number, and email address.

Unfortunately USPS seems to have issues for us with Mexico, Central America, and much of the Southern hemisphere including Africa and South America. But we are working on products right now that will get around this restriction. So if you are a potential customer in one of those locations, please be patient, we'll have something for you eventually. If your need is more urgent, we have found the best solution is to have an American or European friend buy one and bring it with them when they visit your country (the airlines usually accept our packages as luggage size).
