How to Decide What Styel of Watertank Is Most Optimal For Melbourne

There aren’t many consolations to a rainy day– cosy sofa time, soothing sounds of water on the roof, and perhaps a rainbow or a puddle-splash afterwards. But you can add another by installing a water tank to capture a portion of that downpour: it’ll reduce your environmental footprint by lessening your demand on mains water and the amount of stormwater runoff into rivers and oceans, and can also cut your water bill in the longer term.

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

Water for outdoor or indoor use?

Easily the most important issue to consider before you purchase and install a rainwater tank is how you wish to use the water.

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

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

What size rain water tank do I need?

The storage capacity you choose will rely on the size and shape of your household and garden. Round, squat tanks fit adequately under a deck, while slimline water tanks tanks agree with narrow spaces. An underfloor tank or bladder storage system is a good out-of-sight space saver, however, is more expensive.

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

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


Rainwater tanks generally come in the following materials:

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

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

Fibreglass tanks are rust and chemical-resistant and developed to withstand extreme temperatures. They’re not the cheapest possibility, and more suitable for above-ground installation, while all other types can also be set up below ground.

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


Ask your local area council and water supplier which rules and regulations are applicable in your region. You may need to provide a development or building application, and there may be regulations around drinking rainwater or mosquito breeding prevention, along 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 restoring or building, in lieu of retrofitting, you may have to incorporate energy and water-efficient elements in your plans to abide by new legislative requirements.

Extra expenses

When acquiring quotes, ask if there are any further costs for delivery and installation; extra components (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 intend to put it on the ground or below it, through which case you’ll need to factor in the cost of special ground prep or excavation).

If you want to connect the tank to your mains supply of water, think about the cost of a licensed plumber, and charges for any supplementary work that needs to get done to your roof and/or guttering.

Can you obtain a water tank rebate?

Consult 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 rain water 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.
