Selecting The Best Water Tank For Your Home

1 Comment

There are not many consolations to some rainy days — comfy sofa time, soothing sounds of rain falling onto the roof, and perhaps a rainbow or a puddle-splash afterwards. However, you may add a different one by installing any of a selection of slimline rainwater tanks which are designed to catch a certain allowance of the downpour: it will shrink your ecological footprint by lowering your requirement on mains water and the quantity of stormwater runoff into rivers and oceans and may also reduce your water bill in the long run.

Rainwater tanks are far from being considered enormous, round and hideous; they are available in all sizes and shapes which could make effective use of little or catchy urban areas.

Water for indoor or outdoor use?

The most crucial issue to think about before you purchase and install a rainwater tank is the way you would like to utilise the water.

Employing the water outside — for mowing the lawn and washing the car, for instance — would be the simplest way to begin, since you probably only require the provider to put in the tank, instead of a certified plumber. And it is going to instantly cut your intake of mains water.

Save more by simply sending the water into your bathroom, washing machine or hot water supply, but you will need a licensed plumber to attach the tank into your mains supply and be aware you may need them to clean drains before installation to increase the quality of water.

The Size That is Needed

Sizes can range from 5000 litres all the way to a 10000-litre water tank. The capacity you pick will be based on the dimensions and form of your garden and household. Round, squat tanks match nicely under a deck, even if slimline tanks are great for narrow spaces. An underfloor tank or bladder storage process is a fantastic out-of-sight space saver, however, is much more costly.

Your roof area and the yearly rainfall in your area will also need to be considered. To help determine the size and form that is ideal for you, sellers frequently provide calculators on their sites, or your own water jurisdiction could have the ability to assist you.

What do I want to know before purchasing a rainwater tank?

Water tanks normally come from the following substances:

  • Steel tanks are manufactured from corrugated or flat polished metal, which could possibly be galvanised or coated. They frequently arrive with a plastic interior liner (Aquaplate) which increases the lifespan of the tank and provided protection for the water quality.
  • Plastic water tanks are great since rust is not a problem, they’re a fantastic solution for people living close to the sea. Bladders are helpful for water storage under a deck or floor; although their substance is tough, it is not meant for outside installation.
  • Fibreglass water tanks are not the least expensive alternative, and more acceptable for above-ground installation, while the other types may also be installed underground.
  • Concrete tanks, even more frequently employed for industrial and agricultural purposes, will not corrode, melt or get pushed by the wind.


Consult the regional council and water provider which regulations and rules apply in your town. You might have to submit an improvement or construction program, and there might be rules about drinking rainwater or mosquito breeding avoidance, in addition to limitations on the tank place, colour, elevation and labelling or sound regulations to get a pump.
If you’re building or renovating, instead of retrofitting, then you might need to integrate energy and water-efficient characteristics on your strategies to comply with new legislative demands.

Extra prices

When obtaining estimates, ask whether there are any additional prices for delivery and setup; additional materials (like pipes, fittings and taps); optional extras (for example, a first-flush or back-flow-prevention apparatus); a pump (unless it’s possible to use gravity to get water pressure); along with a rack (but maybe you would like to place it to the floor or under it in which case you will want to factor in the expense of special floor prep or excavation).

If you would like to join the tank into your mains water supply, factor in the expense of a certified blocked drain plumber to help clear any issues, and prices for any additional work that should be performed to your roof or guttering.

Check with the regional water or government jurisdiction to find out whether you’re eligible for cash rebate or charge decrease — the response may be based on the magnitude of this tank and if it is connected to a bathroom and/or washing machine.


Rainwater tanks can vary from approximately $700 to $2000, beginning out of a small freestanding version without extras or pump, to big, custom-built versions. Prices vary based upon the dimensions, material, strength and finish of this tank.

Water tanks are a important part of any and every home. The decision into which one you should get should not be taken lightly – make sure you consider every option.
