3 Rainwater Catchment Systems Used At Our Homestead

The heat & humidity here in Texas during a typical summer can create some gardening challenges. And in our area of NE Texas, we’ve been in drought conditions for several years in a row.

It can feel like an expensive and losing battle to keep your garden watered.

But I don’t pay for treated water to irrigate my gardens. They’re all watered with harvested rainwater. Come see three rainwater harvesting systems that work best for us.

Keeping Water Requirements Low

First of all I’m careful to make sure my plants are mulched heavily to conserve water & protect against heat.

Sometimes I use living mulch such as a squash or pumpkin vine, similar to a 3-Sister’s Garden. And sometimes I use spent hay from the hay rings or even the deteriorated straw from the bales I keep around my grapevine. But whatever method I use, I make sure to keep that soil covered.

Thankfully that means most years – even in drought – I’m able to keep the garden going using the 3 rainwater catchment systems we have in place.

NOTE: Now here in NE Texas it’s perfectly legal and oftentimes encouraged to capture & use rainwater.

But from what I understand there are some areas/states that don’t allow it for whatever reason. So be sure to check with your local government & make sure it’s allowed before you proceed with any rainwater catchment system.

Underground Cement Cistern

My vegetable garden measures about 40′ x 20′. I can’t stand the thought of commercially-treated water pumped miles to reach our home just to be dropped onto the ground. So I keep my garden irrigated & productive using only captured rainwater.


A 20-ft deep cement cistern was already here when we built our house. So we decided to put it to good use!

One of our home’s main downspouts was tapped & rainwater from the roof is sent through an underground pipe to the cistern.

To retrieve the water RancherMan obtained a small 1 hp *shallow-well jet pump. That gives me decent pressure for the water coming out of the deep cistern.

Then I just run a water hose to my garden. I use a spray nozzle to direct the water precisely where I need it.

Sometimes you’ve got to know when to give up though. When yet another drought hits & I run out of water in the cistern, I just have to admit that it’s a losing battle this season.

When that happens I let the big garden go for the rest of the summer. I’ve already preserved the bounty and often replant for a fall garden anyway. So that gives me something to look forward to as the garden slips away to the death-grips of drought.

Inexpensive 55-Gallon Food-Safe Barrel

We also have a Porch Addition that I landscaped with large galvanized troughs planted with pretty edibles. My edible landscape garden is irrigated with water from one of two different above-ground rain catchment containers we keep.

One of our backyard water catchment systems is just an inexpensive 55-gallon barrel that has an inlet from a downspout and a spigot for a water hose. We set it up on cinder blocks so there would be a gravity-feed ease for it.

I also placed a huge 30-gallon open-top tub next to it to catch the overflow for even more rainwater when the barrel is full. (I dip a watering can into it).

And remember how I told you before that RancherMan & I like to go to garage sales with my aunt & uncle? Well we picked up this beauty for $15 because it needed a new spigot.

So we replaced the spigot and set our new rain barrel up on cinder blocks at another downspout. RancherMan says it’s about a 55 gallon capacity, plus I’ve also placed another 30-gallon open-top tub next to it as well to catch the overflow. 

Although the photo shoes it uncovered so you can see the volume of water it holds, I have a cover that I put on this bucket when it has water in it to keep it from breeding mosquitoes.

Then when it’s empty I uncover it again before a rain and it fills up in no time flat from just the overflow water. That’s lots of rainwater I have available to me during the drier summer months, y’all!

Galvanized Trough Rainwater Catchment

The final backyard rainwater catchment is actually part of our back porch addition. It’s a 100 gallon water trough connected to another downspout.

I added feeder goldfish to the trough to keep mosquito larva away. They only cost about $0.30 each and I enjoy them so much. Time will tell if they are successful at keeping mosquitos away.

If harvested water runs out I’ll often use gray water to keep the container gardens watered. But typically during the spring those bad boys fill & I have water for a long time, even during drought.

And any little 1/2″ or so rain will fill them up again!

We capture rainwater for all our outside irrigation needs. Come see 3 easy setups we use here on the Homestead. #TexasHomesteader

So that’s how 100% of our outside irrigation is rainwater. (or gray water during prolonged drought.)

None of the systems are fancy or expensive, but they all work great to keep our gardens watered with free, untreated water!

    Out here in western Oregon we don’t have too much trouble with water. Ours comes via a gravity feed set up. The source is across the creek on a hillside that belongs to someone else. When my father built the house he was able to get water rights from the native American lady who owned the property then. We’ve never run dry and I never worried about how much water I was using until the birdman who lives with me set us up with a water purification system. Now I’m quite a bit more careful. One shower faucet in the house drips kind of randomly. I keep a bucket under that tap and when it’s full I use it to flush the toilet. I also leave it in the tub while I wait for the water to get up to temperature. I also have some buckets sitting out side to simply catch rain water (not much of that right now). I can either use it to flush or water some of my potted plants that live out on the deck. All that being said this has been a horrible forest fire season in Oregon. Global warming – it’s happening and fires are creating havoc in many places around the globe. I’m always happy to read about you and other people living lightly on planet earth. Meanwhile, the darling little screech owls are doing well. We sit out in the evening and watch the parents bringing them food. Life doesn’t get much better than that. Stay safe, Candace

      I love your water conservation efforts Candace! And your sweet screech owls? Just, wow. I know you’re in bliss there! Stay safe from the wildfires. ~TxH~

    Been doing some reading up on this subject of putting fish in stock tanks; feeder goldfish or minnows.
    Also read that if you put a clean concrete block in the water the goldfish will have babies as they have a place to hide. fish; Concrete block, baby fish condo — sounds like a plan

    Thanks Tammy. Hubby was going to build a cover to put over the tank
    and even bought the materials for it but told him that I wanted to put fish
    in the tank. He just laughed at me and thought I was nuts, so of
    course I had to come to you to prove him wrong, that yes, a person can put gold
    fish in an outside water tank. He said that he would be willing to
    try it.. 🙂
    Enjoy your day and keep cool

    you having goldfish in your stock tank; how do they stay alive in the cold freezing winter months and wondered just how many goldfish you have in your tank? Do you use a heater to keep the water from freezing?

    1. Texas Homesteader Post author

      Ya know Colleen, from what I understand these goldfish can take the cold and survive just fine. Plus the odds of the entire tank freezing solid are virtually non existent. But even if there’s ice on top (from what I understand) they can survive just fine. We haven’t had them long – only about 2 months – so we’ve not overwintered them yet. I’ll let you know how it goes! ~TxH~
