How To Setup A Rainwater Catchment System

Rain catchment, rain harvesting, or rain barrels are a favorite project of many gardeners and homesteaders.  The truth is that water is the basis of all life on our homesteads and gardens, so it makes sense that we look to take advantage of the rain that is already falling on our home.  Catching water to use is a great way to reduce our water bills.

For each square foot of catchment we create we capture .6 gallons per inch of rain.  Where I live in North Carolina it rains an average of 42 inches per year, if we consider the average size a home in the US (2,400 square feet) that means that if we were to catch all the rain that fell on that roof in a year, we would capture over 60,000 gallons!  That’s a lot of water!

Parts You Need To Catch Rain Water

Regardless of the size and scale of your system you’ll need a few basic parts to put it all together.  Below this section I dig into some of the details you also want to consider, but at it’s basics you’ll need the following.

Catchment Surface

This can be any flat surface where water lands and is channeled where we want to store it.  In many cases people look to their roofs because it’s a large surface that already has gutters which will collect and channel the water into a few points where we can collect.  This could be any surface so get creative.  It could be the roof of our chicken coop, the roof of a barn, it could even be a parking lot that is graded to drain the water into a settlement pond or swale.

The material of this surface can be almost anything, but do consider what that surface introduces into the water.  If for instance you have a shingle roof, there are a lot of chemicals in them which prevent biological growth and hold up in the sun for years.  These can transfer to your water if you’re not careful.  In general the best roof surface is is a metal roof, because it is less likely to impart any bad chemicals into your water and is pretty easy to clean if it gets real dirty.

First Flush Diverter

As with anything outside, things can get dirty.  In the case of roofs and large open surfaces, we find that dust, dirt, and pollen settle onto roofs.  Additionally you’ll have birds pooping on it, bugs dying onto it and other things making your roof a dirty place.  We obviously don’t want any of these things in our water, and while we can’t prevent it, we can use a first flush diverter to try to avoid the bulk of this going into our storage tanks.

A first flush diverter is a mechanical device that lets us wash of the roof with all the gunk in it, then divert the now cleaner water to our tanks.  This can be done a few different ways, a whole bunch of options can be found online both for purchase and DIY.  The video below shows you one way you can do this.

Storage Tank

catchment tanksLater on I’ll go into how to calculate how much storage you need, but suffice to say you’ll need a good bit of storage to really cover your needs.  There are a lot of DIY options out there with 55 gallon drums or 120 gallon totes, but in past experience I’ve found these to be to be a lot of extra hassle and in the end you don’t save as much because you’ll need a bunch of them, each time adding in connections that can fail.  Typically you can find barrels for around $20 a piece, but then you’ll spend $10 or more in PVC parts to interconnect them.

A 500 gallon water tank can be purchased for around $300 if you’re able to go pick it up, shipping is the tough part.  With a tank that size you’re going to want to pour a pad to set it on for stability and safety, so you should factor that into the cost.

Is Rain Water Safe?

Yes and no.  According to Anne Marie Helmenstine, Ph.D. of Biomedical Sciences rain water is generally pretty safe to drink or use on your garden.  It’s always recommended to filter and purify if you’re not sure about the source.  When we are talking about ingesting something we need to do our research and consult experts (I’m not one).

Where I think most people will run into trouble is in the catchment and storage of the water.  The water as it falls from the sky is pretty clean, but once it lands on a surface and is move into a tank, you can run into issues with less than desirable things being introduced.  Even with water from the sky, there may be some pollution, dust or other biological elements in the water.  So always filter and purify.

How Much Water Do You Need?

I found that water catchment is only actually useful if you go big, small rain barrels are a fun project, but gardens require a lot of water and most can’t keep up in any significant way.  A general rule is you need about 0.8 gallons of water per square feet per week for your garden.  This will vary based on your climate, soil and crops, but it’s a good place to start.

So figure out how many square feet of garden you have, times that by 0.8 gallons to figure out your total weekly needs.  Example: 1000 square feet of garden will need 800 gallons per week.  It’s also important to consider the averages for the month in your growing season.  A quick google search for “monthly rainfall in…” will give you a chart, for me I get 3 inches per month or more all year round, so I need to consider that when sizing my system.

If I had a house that was 1,500 square feet of roof times .6 gallons per sq/ft times 3 inches of rain in the month, I can collect a maximum of 2,700 gallons per month.  This would support a maximum of 843 square feet of garden (2700 divided by 4 weeks divided by .8 gallons = max garden size).  So you can see that you need a pretty big area to collect, to store and the infrastructure to move it from one place to another.

Storing Water

Keeping water stored up is no small task, mainly because of the quantity we need and how heavy it is.  At 8.5 lbs per gallon, if we take the above example that means we need support over 11 tons!  The tank would need to be 8 feet across and 9 feet tall, which typically costs $1500-$2500.  These are all very big numbers obviously and even at their scale, it’s only supporting a smallish garden.

water barell

Tanks this size are a lot to transport, to move and to install.  If you’re going to go above 100 gallons I strongly suggest getting a cement footing poured so that you know the surface below can safely handle the weight, plus you’re going to want at least a little elevation so that you can fit a bucket under the bottom drain or have working room for pipe connections.  Because of the size, the weight of the water will provide pressure to push the water out the bottom pretty well.

When you’re storing water in bulk you need to make sure that you prevent foreign bodies from getting introduced, like a mouse climbing in and drowning, or bugs falling in and algae forming. We can do this through various methods using hardware cloth, opaque containers and in some cases chemical controls.

Low Pressure System

One advantage of municipal or well water systems is they are pressurized, typically to around 40 PSI (pounds per square inch).  When we capture water we don’t always have that much pressure so we can do a few things to overcome it.

drip tape irrigation

First is we can get the water into an elevated position.  If you’re able to capture the water in a high spot and put your garden or home in a lower spot, we can use that elevation change to our advantage.  For every foot elevation we can get our water, we will gain about .4 PSI.  So if we are able to raise the water to 100 feet above where we need it, say on top of a hill, we could get 40 psi at our spigot down the hill.

Most people don’t have that drastic of a change in their topography, so instead we can use low pressure irrigation to overcome any limitations.  To meet this need there are now several drip tape solutions that are designed with low pressure in mind.  In some cases you’ll only need around 10 psi  (25 feet of elevation) to get your garden watered.

Filtration & Purification

Depending on your setup and your use you might want to consider filtration and/or purification in line somewhere. The difference between these two processes is important to understand.  Simply put, the main difference lies in the level of protection they provide. Generally speaking, a water filter is designed to remove waterborne protozoa and bacteria, but not viruses. A water purifier is designed to combat all three classes of microbes, including viruses.

dirty water

If you want to go this route, a commercial system can be had for not too much money and there are a lot of good options.  Since we need to remove things measured in microns, our ability to come up with DIY solutions are just not possible here.

So that’s some of the basics of catching water for use in your garden and potentially as water in the home if you’re off grid.  Make sure you read up, do your home work here because there are some finer points to get right.

Getting Started With Chickens

Chickens are, as I like to put it, the gateway animal.  You start out with chickens and then all a sudden you have your eye on a few goals, a couple pigs and maybe even a mini Dexter cow.  I have had chickens several times through out my life and always loved having them around. Even years ago when I got my first chickens I made a lot of success very quickly and the entire process was a lot of fun.

starting with chickens

The nice thing about keeping chickens is they are quite easy to take care of, requires a few minutes a day to tend, in a pinch can be left for a long weekend and if you travel you can teach someone to take care of them quickly.  Of course as with any animal, owning chickens you need to take it seriously and make sure you understand that their welfare is your responsibility, so make sure to consider it carefully.

Know Your Local Laws

The first thing you need to do before you do anything is make sure that keeping chickens is allowed.  You’ll need to check with the local authorities, see if you have any rules in your home owners association or deed restrictions and then also consider your neighbors.

golden comet chicken In my city I’m allowed to have up to 50 birds per acre, the coop must be offset from any property line by 15 feet and obtain a permit for $10 a year.  Your city or town may be different, so make sure you do your homework!

Learn All You Can

Obviously if you’re reading this post, you want to learn about starting a chicken farm and it may even be because you’re thinking about getting chickens of your own (go for it!).  Use this post as a jumping off point to learn as much as you can about the various aspects of chickens.  You’re going to make mistakes and that is okay, we are learning, so don’t beat yourself up if you’re doing your best to care for these animals.

Get Setup Ahead Of Time

Once you’ve researched your local laws you want to get setup with some basic infrastructure.  You’re going to need a few things so you can be ready for your chickens.  You should consider the following

Brooder

If you’re going to raise chickens from freshly hatched babies (chicks) you will need what is called a brooder.  A brooder is like a nursery for the chicks where we protect them a little bit more, give them some added heat and let them grow a bit before you let them out into the real world.  I typically do this in a large Rubbermaid tub with a heat lamp and some bedding.

We have a whole post on how to set up a brooder and raise chicks. Below is a video I have of some baby quail I raised a few years ago from eggs. Their setup was a bit simpler, but you get the idea.

Build A Coop

A coop is just what we call the house we keep our chickens in at night.  During the day we will let them free range (go were ever they want) or let them into a run (a fenced area that provides some protection).  The coop needs to be about 2 square feet for each chicken you have.  Much more than 2-3 feet per bird assuming they have more room to range during the day doesn’t do much because they all like to pile on a roost and cuddle up with each other anyway.

chicken on roost in coopA roost is just a bar that chickens like to sit on, usually about a foot or so off the floor of the coop or ground.  I’ve had chickens that all piled onto a single bar leaving several empty and then I’ve had others that didn’t use them at all.  I usually add them because it seems like most chickens like to roost because it makes them feel a little safer.  The top most roost is often taken up by the alpha hen and the rooster if you have one, but some flocks don’t get too tied up in pecking order.

You want to make sure that there is at least some ventilation, but make sure it hardware cloth over it so predators can’t get in. The rule of thumb is around 1 square foot of ventilation per 10 square feet of coop.

The last parts of a coop are your nesting boxes for the chickens to lay their eggs in (usually one box per 3-4 birds) and some sort of bedding to catch droppings from.  Chickens put out a lot of droppings and they tend to concentrate under the roost bars.  However you plan to handle droppings, make it bomb proof because it can get messy quickly and if you build your coop to easily clean out, you can make your life a lot easier.  More on coops coming soon.

Chicken Tractors And Chicken Runs

Many people who want to get into raising chickens want to try a mobile chicken tractor, which is basically a coop with no bottom that you move to fresh grass every few days.  I’ve done both a fixed coop and chicken tractors and I think chicken tractors are my favorite because it cuts down on the cleaning (no floors, the chickens just poop on the grass) and it reduces the amount of feed I need to buy.

Here is my old chicken tractor:

There are a few things you need to consider if you decide to go the chicken tractor.  Whatever coop you design it should be able to be moved easily by the smallest person in your household, it makes it difficult if only some of the people can actually move it each day.

Finally make sure you have enough room, if you have more than a few chickens you’ll need to move that coop most days so that the chickens do remove all the vegetation in that one spot to the point that it can’t bounce back.  You want the grass to get roughed up a bit, but no more.  This will let the grass bounce back and grow stronger.  Having enough space is easier in the summer months because things grow so quickly, but in the winter you may find that a spot where the chickens were takes 30-60 days to heal.

Life And Death On The Farmstead

With any animals it’s great to have animals around your yard, it can bring a lot of good energy, fun and happiness.  The other side of the coin is that with life comes the end of if.  Sometimes chickens get sick, sometimes a predator circumvents our fences, or they might just grow old and die.

hens and a rooster

For good caretakers these days are few and far between, but it is a reality of this lifestyle.  When I bought my first chicks I ended up with several roosters despite me trying to avoid it.  As they grew they began to struggle for dominance as the alpha rooster.  It was at that point I had tried giving them away, but couldn’t find anyone that would take them even for free.  As they fought I knew the only outcome was that there would be only one alpha and the rest would suffer injuries or death from the skirmishes that were taking place.

It was then I realized they would end up being pecked to death by the alpha rooster.  I wasn’t comfortable with a prolonged and painful death, so I made the decision to process them for meat.  It was a difficult and somber affair as I did the deed, and while I was resolved in my mind, it didn’t make it any easier as I placed them in the kill cone and nicked their artery with a knife.

Just understand that it’s mostly good, but there are a few bad days too.

Self Sufficiency

Not only is keeping chickens pretty easy and a lot of fun, but the eggs and potentially meat are a solid first step into self sufficiency.  If you think about it, we grow a lot of things in out garden and while they are loaded with nutrients, vitamins and minerals, they are often very low in calories or protein.  It’s great to eat healthy, but if we want to make our way to self sufficiency, we need to figure a way to cover our caloric and protein needs too and eggs help in that goal.

nutrition in a farm eggAs you can see an egg has some good calories and a fair bit of protein and you get an egg per chicken each day in many cases.  Compare that to a tomato which can take 90 days to grow and only has 22 calories.

Having a few eggs a day for breakfast or a quiche for lunch or dinner is a great way to start making up some of the calories that we need, which means we don’t have to rely on the grocery store as much.  Eggs can even be a way to make a few bucks to cover the cost of feed and if you ever need a chicken sitter, them keeping the eggs is often compensation enough.

Letting Chickens Work For You

my chickens in my gardenNot only are chickens a great source of food, but they can be helpful in reducing your work load.  Chickens by their nature scratch at the dirt, root for bugs and grubs, and till up the first inch of soil.  We can utilizing their natural tendencies to get things done in our gardens. Setting chickens loose on compost piles will be like letting a child loose in a candy shop.  They’ll turn the compost, peck out any grubs and bugs (breaking the pest life cycle) and add their manure to the pile all in one fell swoop.

I’ll often move my chickens to my garden area before I begin to prep the garden for a new season.  Since my garden area is fenced in for deer, I set them up there for a month and let them take everything to bare dirt.  If there are any perennial plants or plants I want to keep, I’ll just fence them off so the chickens can get to them.  After a few weeks the ground is often removed of weeds, bugs and a fair bit of manure has been scratched into the soil.

Chickens are a really great first step into bringing animals into the mix on your land and they have a lot of upsides.   So if you are thinking about chickens, check out some of the other post here on the site and let us know in the comments what your plans are!

Next Generation Home

So I recently read a comment written by one of our readers, Jason, he made an interesting point when he said (paraphrasing) at what point can we take a house and stop it from consuming, to producing.  This is a very interest notion, traditionally houses and their systems require resources to operate, to maintain, to use etc.  Now being a producer could mean the house itself produces, a system within the house, the person who lives in the house; how can we turn this negative into a positive?

So it left me wondering how could I have a house that doesn’t consume, but produces; while this might actually be impossible if you start looking at the laws of physics it might be a more accurate statement that a house that can offset the inputs with it’s outputs.  But is this even possible?

The average American home creates 4 tons of waste in just its construction, the average house produces almost 90,000 pounds of carbon emissions.  Now a Tiny House will drastically reduces the amount you have to offset, but it will still be a good bit.  Here are some ideas that could help us get closer to making our house a producer, not a consumer.

Reduce your usage right off the bat

First and foremost I would urge you to first reduce what you consume, being conscious of what you consume, if you have to purchase something, think about how you can extend the life of it or if you can use something that you have to preform the function.  Finally if you have to use something, recycle or up-cycle it.

Grow your home

How about instead of building a home, you grow one!  Here are two idea, the first is a real example that is being used already, the other is a concept that is grown from protein structures.

Green Roofs

Not only does the roof process CO2, but it can grow food and drastically reduce cooling and heating costs.  This isn’t a new concept but still an attractive concept.

Green Power

Now obviously it take energy and resources to produce solar panels, geo-thermal taps, and wind turbines, so you have to take into account how much you have to produce to just offset the production, but I would suspect you could make up the difference and then some over the lifetime of the products.

What other ideas could make your home a producer, not a consumer?

How Green Is The Next National Security Plan

So I have been kicking around this idea for a week or two now and it certainly isn’t a entirely new concept, but it is the concept that by taking actions on the green front, will actually enhance our security.  Now before we get into this, I would like to steer clear of political aspect of this discussion, with the side note those who focus on Green initiatives are sometimes seen as the polar opposites to those who focus on National Security.  I think many would disagree with this view and those who didn’t could be brought to the table and see both sides.    The other thing that I would assert is that this concept isn’t exclusive to America, I speak generally about the world.  So here are a few examples of the threats I see and their solutions.

To expand on what I consider national security I think it is important to note that national security extends beyond terrorism and nuclear armaments.  It includes anything from any source that can threaten our safety, well being and long term livability.  This includes drought, blight, natural disaster, war, terrorism, etc.

Food

If you have ever seen the documentary Food Inc. (which I highly recommend) talks about how 90% of the corn and 60% of all soy beans come from one company that are one strain.  This means that a blight, whether engineered or natural, were to hit our country, we would loose 90% of all our corn in one fell swoop.  This is pretty concerning when you truly understand how much of our food comes form corn and in really unexpected forms.  If you look at how many individual strains of food we actually grow for the majority of our food, we are talking 22 types of plants with a specific strain make up 80% of our food.  Can we afford to lose 80% of our food?

So how to fix it.  We first need to encourage a larger diversity of plants, the idea being that some blights will effect some strains of plants and not others.  We then need to decentralize our food production, moving food production closer to the people.  This will take time, money and in all honesty could turn out to be more expensive as economies of scale decreases, but we also need to put a price on sleeping soundly at night.

Energy

I don’t think it takes any stretch of the imagination to see how us depending on other countries  for oil is a bad thing.  Especially when you consider that most sources of this oil are in politically unstable areas.  One thing we see as an option is to drill off shore, which as of late, we have seen how bad that has turned out to be.  The fact is that there may be a large volume of oil out there, but it is still a finite resource and it is getting harder and harder to get to.  With increased difficulty comes increased risk and while innovations can mitigate those risks, I am still left doubting it.

So the solution, I say save what we have in our country and lets focus on sustainable technologies.  While people talk about nuclear, I have to remind them of the heavy subsidies they get every year.  Nuclear is a pretty mature technology, I assert that if we took these subsidies and used them to develop solar/wind into mature technologies that we could come out on top.  The added benefit to this is that we can then decentralize power production to avoid 50 well place bombs to take out most of our power production.

To sum up I think that we are beginning to see how Green is better for everyone in many ways.  I found this video done by Pew which is pretty interesting.
