Rainwater Storage Tanks - Sizes

Rainwater Storage tanks do literally come in 'all shapes and sizes' and just about any color that you could choose.

It is not the purpose of this hub to give you the dimensions and shape of every available water tank. Rather to give you the information needed to help you decide if you actually want a water storage tank.

My household survives on water harvested from the rainfall and we would not want it any other way. If we ever move from our 2 acre property we will definitely be installing some form of rainwater capture and storage system.

So many shapes | so many sizes

From the observations I have made through my years of research there is such a large number of different types of tanks available, I could not possible cover them all in this one Hub, they are made from just about any material you can name.

If anyone has come across any other type or shape let me know and I will include it here for everyones benefit!

I have sorted through all of my research and short listed the most popular for your perusal!

Corrugated Galvanized Steel

Corrugated Galvanized Steel. These tanks are hand riveted and sealed with compound ( In Australia the old method of Soldering has been banned) and if required for potable water they are internally coated with approved certified coatings.

Linings are also available to fit inside the tank. It is recommended that they be installed on a concrete pad.
Although very popular in the past these corrugated galvanized tanks are being outsold by the Plastic (Polyethylene) tanks, Possibly due to the lower cost and the Poly tanks can look nicer and can be manufacture in just about any form and colored to fit into the surrounding environment.

Poly tanks and shape any size!

Plastic (Polyethylene)

Plastic (Polyethylene) water storage tanks. Due to the manufacturing process these tanks can come in just about any shape or form you can imagine, round, slimline (becoming popular due to houses being built on smaller blocks) and rectangular. Research shows that the size of these tanks can vary between 700 and 5,000 litres ? I believe that they are now even bigger ?
These Poly (as they are now called) water storage tanks also can be purchased in a variety of colors including, greens, reds, browns, beige and many more.

Water Storage Tanks - Concrete

Concrete water storage tanks are very popular in Australia and are manufactured to strict regulations with bases up to 4 inches thick , walls up to 2 inches thick and the roof can be up to 4 inches thick.

All concrete is reinforced with either galvanized welded mesh , wire and / or rods. The larger models have a center support column.
Capacities can vary from 1000 gallons (5000 litres) to 5500 gallons (25,000 litres)

On my property we have 3 concrete tanks capable of holding 15,000 gals (67,000 litres) of water. We have had overflow only on 2 occasions!

Bladder Water storage tanks

Bladder water storage tanks are now popular due to lack of space in the modern home and a requirement of some building authorities that water storage is now mandatory in new homes.

Bladder storage tanks are becoming more popular because they can be installed under houses, decks etc. and can be removed when the owner decides to relocate.

Potable water bladder tanks are made out of material approved for storing consumable liquids and come in sizes up to about 10,000 gallons. The job of fitting this bladder tanks under a house can be quite formidable and it is recommended to have them Specialist fitted.

Dimensions and capacities

To give you some idea on the size of tank for the required amount of water I have listed below the dimensions and approximate capacity for some popular tank sizes, I hope this information is useful?

Diameter
Height
Capacity
3 feet (0.9mtr)
6 feet (1.80mtr)
220 gals (1,000ltr)
7.8 feet (2.40mtr)
6 feet (1.80mtr)
1770 gals (8,000ltr)
 
 
 
Capacity of tanks as an example for the purpose of this exercise I have taken the liberty of rounding off numbers and using a conversion factor of 1 Gallon = 4.5 litres and 1 cubic foot = 7.5 gallons

Underground Tanks

Water Storage Tanks underground

These days some home builders have decided that the above ground storage tanks are not to their liking and more people are opting to have the water storage tanks installed underground,  similar to how a petrol station has its fuel tanks underground!

These tanks can be any shape, but most are designed using a round shape because I believe it is a stronger structure and can withstand many years of pressure from the surrounding fill.

Underground water storage tanks have quaint names such as "Donut:" and "Bagel" for obvious reasons.

      Christoph, you raise a very good point. You may have only been joking but during the terrible bush fires last year where there were so many people killed, a number of lives were saved by people jumping into the large water tanks. I believe they were the concrete structured water tanks.

      Mate, Thanks for dropping by it's always a pleasure to see you :-)

      hypnodude, thanks very much for the thumbs up, in Victoria especially our water supply seems to be going backwards and the cost of water is due to sky rocket. So every little helps.

      Thanks for dropping in :-)

      Darlene, thanks for you input. I don't know what other countries are like but in my town of Melbourne you could pop your head over the back fence of any decent gardener and see a tank of some description. From plastic wheelie bins to cut off 44 gallon drums.

      Oliversmum, thanks for your great comment. I do agree with you about the bladder tanks! They are becoming very popular as they become cheaper to buy.

      It is not that hard to set up some sort of tank to gather water even if it is only used to water the garden.

      Oliversmum, thanks again for your kind comment :-)

      It's a bit less practical an idea for me since I live in the city. But I think it's a wonderful idea, and I actually think many cities could benefit by capturing more of the stuff to be processed. Never hurts, IMO, to have a conservation effort of any sort.

      A timely and useful hub as usual agvulpes. I hope more people consider the advantages of these modern storage systems. If I were in a high bushfire risk area I would opt for the concrete one I think.

      Springboard, thanks for droppin by. Even though it may not be practical we can all practice water saving methods.

      It really annoys me to see all of that water gushing down the drain after a rain storm, you would think there would be some way of saving the millions of gallons being wasted!

      earnestshub, thanks for the kind comment. I also would opt for concrete tanks in a high bushfire risk area. I believe that during our last bad fires quite a few people saved their own lives by jumping into a full concrete water storage tank.

      Dale Mazurek , thanks for dropping in and leaving a great comment.

      I am honored that you would put one of my Hubs on your Blog.

      It's a great idea you have going there and I would advise anyone to go over and have a look. It would be great to see more promotion of Hubbers away from HubPages and to date yours is one of the best I have seen.

      Dale , thanks again :-)
