How to Decide What Kind Of Rainwater Tank Rain Water Tank Is Most Optimal For Victorialeelbourne, Victoria

There aren’t many consolations to a rainy day– cosy couch time, soothing sounds of drops on the roof, and possibly a rainbow or a puddle-splash afterwards. But you can add another by building a water tank to capture a portion of that downpour: it will decrease your environmental footprint by decreasing your demand on mains water and the volume of stormwater runoff into rivers and oceans, and can also trim your water bill in the long term.

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

Water for outdoor or indoor usage?

The absolute most important issue to consider before you purchase and install a water tank is how you intend to use the water.

Utilizing the water outdoors– for watering the garden and washing the car, for example– is the most convenient way to start, as you most likely just need the supplier to install the rainwater tank, instead of a licensed plumber. And it will instantly cut your usage of mains water.

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

What size rain water tank do I need?

The storage capacity you choose will depend on the shapes and size of your household and garden. Round, squat tanks fit adequately under a deck, while slimline 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 location will also need to be considered. To help determine the size and shape that’s right for you, sellers often provide calculators on their sites, or your water authority may have the opportunity to help.

What else do I need to know before buying a rainwater tank?


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

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

Polyethylene (plastic) tanks are prominent as they are relatively cheap and durable. Because rust isn’t a problem, they are a good option for people living near the coast. Other synthetic materials, like PVC and geotextile, are used for bladder storage. Bladders are useful 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 created to withstand extreme heat levels. They’re not the cheapest possibility, and more suitable for above-ground installation, while all other types can also be installed below ground.

Concrete tanks, more frequently 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 regional council and water supplier which rules and regulations are applicable in your area. You may need to submit a development or building application, and there may be regulations around drinking rainwater or mosquito breeding prevention, as well as restrictions on the tank’s placement, colour, height and labelling or noise regulations for a pump.

Are you refurbishing, building new or retrofitting?

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

Extra costs

When securing quotes, ask 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, through which case you’ll need to look into the cost of special ground prep or excavation).

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

Can you get 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 rainwater 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 on the size, material, finish and strength of the tank.
