How to Choose What Styel of Watertank Is Best Suited For Melbourne

There aren’t many consolations to a rainy day– cosy lounge time, soothing sounds of water on the roof, and maybe a rainbow or a puddle-splash afterwards. But you can add another by attaching a water tank to capture a bit of that downpour: it will diminish your environmental footprint by lessening your demand on mains water and the volume of stormwater runoff into rivers and oceans, and can also cut your water bill in the long term.

Rainwater tanks are no longer just huge, round and bad-looking; they are available in all sizes and shapes that can make efficient use of small or tricky urban spaces.

Water for outdoor or indoor application?

Easily the most important issue to consider before you get and install a water tank is how you want to use the water.

Utilizing the water outdoors– for watering the garden and washing the car, for example– is the best way to start, as you probably just need the supplier to set up the water tank, instead of a licensed plumber. And it will immediately cut your utilization of mains water.

Save lots more by sending the rainwaer to your toilet, washing machine or water system, but you’ll need to have a licensed plumber to connect the tank to your mains supply.

What size tank do I need to have?

The volume you choose will hinge on the shapes and size of your household and garden. Round, squat tanks fit effectively under a deck, while slimline tanks are good for narrow spaces. An underfloor tank or bladder storage system is a good out-of-sight space saver, but is more expensive.

Your roof area and the annual rainfall in your area will also need to be considered. To help determine the size and shape that’s correct for you, sellers often provide calculators on their internet sites, or your water authority may have the opportunity to help.

What else do I need to identify before acquiring a rain water tank?


Rain water tanks normally can be found in the following materials:

Metal tanks are created from corrugated or flat rolled metal, which might be galvanised or coated. They often incorporate a plastic inner lining (Aquaplate) that will increase the life of the tank and safeguard the water quality.

Polyethylene (plastic) tanks are well-liked as they are comparatively cheap and durable. Because rust isn’t a problem, they are a good option for people living near the sea. Other synthetic materials, like PVC and geotextile, are utilized for bladder storage. Bladders work for water storage below a deck or floor; while their material is strong, it’s not intended for outdoor installation.

Fibreglass tanks are rust and chemical-resistant and designed to withstand extreme temperature levels. They’re not the cheapest alternative, and preferable for above-ground installation, while all other styles can also be installed below ground.

Concrete tanks, more often used for agricultural and industrial intentions, won’t rust, burn, melt or blow away. They may be bought ready-made, or customized onsite.


Ask your community council and water supplier which rules and regulations are applicable in your location. You may need to forward a development or building application, and there may be policies around drinking rainwater or mosquito breeding prevention, together with restrictions on the tank’s location, colour, height and labelling or noise regulations for a pump.

Are you remodeling, building new or retrofitting?

If you are remodeling or building, as opposed to retrofitting, you may need to incorporate energy and water-efficient attributes in your plans to adhere to new legislative requirements.

Extra expenditures

When securing quotes, inquire if there are any additional costs for delivery and installation; extra products (such as pipes, fittings and taps); optional extras (such as a first-flush or backflow-prevention device); a pump (unless you can use gravity for water pressure); and a stand (unless you want to put it on the ground or below it, in which case you’ll need to look into the cost of special ground prep or excavation).

If you would like to connect the tank to your mains water system, factor in the cost of a licensed plumber, and prices for any additional work that needs to be done to your roof and/or guttering.

Can you access a water tank rebate?

Contact your local water or government authority to see if you’re entitled to a cash discount or bill reduction– the answer may hinge on the size of the tank and whether it’s connected to a toilet and/or washing machine.


Rainwater tanks can fluctuate from around $700 to $2000, beginning with a small, freestanding model without pump or extras, to large, custom-built models. Costs vary depending upon the size, material, finish and strength of the tank.
