Water Tanks/Cisterns

I STRONGLY RECOMMEND YOU INVEST ONLY IN TANKS/CISTERNS THAT ARE RATED FOR POTABLE WATER STORAGE AND USE, EVEN IF YOU DON’T EXPECT TO USE THE WATER FOR DRINKING &/OR DOMESTIC USE. WHY? BECAUSE THE HIGHER THE QUALITY OF THE HARVESTED AND STORED RAINWATER, THE MORE OPTIONS YOU HAVE FOR ITS POTENTIAL USE. TANKS NOT RATED FOR POTABLE WATER STORAGE OFTEN CONTAIN TOXIC BIOCIDES THAT WILL LEACH INTO YOUR WATER. SO DON’T SULLY YOUR WATER WITH TOXIC OR CONTAMINATED MATERIALS OR COMPONENTS.

Plastic Tanks

If placed above ground be sure tank is UV-resistant for durability, and light-proof so algae will not grow in tank. Select tanks for potable water storage.

Bushman Tanks – USA
Check out their plastic slim tanks for urban applications. They have a small footprint and can double as cistern walls or cistern fences along property lines. But I am NOT a fan of Bushman tanks. I find their construction to be of a lower quality than other brands and their 3-inch bulkheads are of poor quality, so I go to the extra cost of replacing these bulkheads with higher quality bulkheads such as those offered by Norwesco.

Steel Culverts (to make your own culvert cisterns)

Caution: It is very common for steel culvert tanks to leak, and to rust.
The seals of the tanks need to be thoroughly cleaned before sealing with caulking. One local water harvesting company cleans the seals with carburetor cleaner that sprays deep into the seals before applying the caulking.
Another common leak is the seam where the culvert enters its concrete base.
They tend to rust anywhere the galvanized coating has been scratched (and often there are many scratches).
As a more durable, leak-free alternative, Southern Arizona Rain Gutters has worked with the manufacturer of large corrugated steel tanks with an interior bladder to make 4-foot and 5-foot diameter tanks with interior bladders. If you are set on the look of a culvert tank, you may want to look into this option.

Look up “culverts” in your phone book yellow pages.

Arizona Culvert of Casa Grande
This company makes culverts in 6″ increments, from 1′ to 12′ diameter, and any length (nearest foot). 
2010 Price for 42″-60″ culverts was in the range of $30-$50/foot. 
Delivery to Tucson (2010 price) was $250 for 1 or several culverts; if you can wait until they are making other deliveries to Tucson, you can save 50% or more on the delivery charge.
I recommend you build culvert cisterns no smaller in diameter than 4′. I find the smaller diameters are harder to construct, and don’t offer enough storage capacity.

Precast Ferrocement Septic Tanks (made for cistern use)

Make sure manufacturer uses concrete and/or sealer rated for potable water contact.
You want to avoid use of concrete that has fly ash, which can contain toxic heavy metals.
Instructions on customizing new ferrocement septic tanks to act as cisterns for non-potable water are provided in Rainwater Harvesting for Drylands and Beyond, Volume 3.

Look up “septic tank manufacturers” in your phone book yellow pages.

Rain Barrels (premanufactured)

These are typically too undersized to be considered a true cistern, but they can get you started. I consider rain barrels rain toys – too small to be the real deal (unless collecting water from a very small roof surface).

Vela Creations’ Building a Cistern: Step-by-step instructions on how to build a cistern with a shell and liner
Abe Connally of Vela Creations notes, “The roof is tricky because most people are not familiar with the material. But, it holds up well and is very forgiving. If I had all the money and machinery in the world, I’d make a conical roof out of metal, but it’s not really that easy in a backyard. If it’s just for irrigation, a pool liner is the cheapest way to go, and we can built a 6000-gallon tank for about $750 or less. We also have one we made out of a pond liner, and it works well, too. For a potable tank, the liner is more expensive, and the total tank cost about $1000. I like the cost, and it’s fairly easy to put them together, even low-skilled workers can assemble one in a couple of days. I eventually want to make one with an eave, so it didn’t even need an external roof. It would be a self-filling rain tank, and spread out further away from the homestead, it could give water to wildlife or help establish native trees and plants.”
