How to Choose What Type of Water Tank 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 possibly a rainbow or a puddle-splash afterwards. But you can add yet another by installing a water tank to capture some of that downpour: it will reduce your environmental footprint by lessening your demand on mains water and the quantity of stormwater runoff into rivers and oceans, and can also reduce your water bill in the long run.

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

water tanks brisbane for outdoor or indoor application?

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

Employing the water outdoors– for watering the garden and washing the car, for instance– is the simplest way to start, as you most likely just need the supplier to install the rainwater tank, rather than a licensed plumber. And it will immediately cut your consumption of mains water.

Save much more by sending the rain water to your toilet, washing machine or hot water system, but you’ll require a licensed plumber to connect the water tank to your mains supply.

What size water tank do I need to have?

The volume you choose will depend on the size and shape 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 region will also need to be considered. To help determine the size and shape that’s correct for you, sellers often provide calculators on their websites, or your water authority may be able to help.

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

Materials

Rain water tanks typically are available in the following materials:

Metal tanks are created 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 protect the water quality.

Polyethylene (plastic) tanks are prominent as they are comparatively cheap and durable. Because rust isn’t a problem, they are a pretty good option for people living near the sea. Other synthetic materials, such as PVC and geotextile, are used 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 designed to withstand extreme temperature levels. They’re not the cheapest option, and better for above-ground installation, while all other styles can also be installed below ground.

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

Regulations

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 policies around drinking rainwater or mosquito breeding prevention, as well as restrictions on the tank’s location, colour, height and labelling or noise regulations for a pump.

Are you renovating, building new or retrofitting?

If you are renovating or building, instead of retrofitting, you may need to incorporate energy and water-efficient attributes in your plans to fulfill new legislative requirements.

Extra costs

When getting 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 intend to put it on the ground or below it, by 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 supply of water, factor in the cost of a licensed plumber, and expenses for any supplementary work that needs to get done to your roof and/or guttering.

Can you access a water tank rebate?

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

Cost

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 basing on the size, material, finish and strength of the tank.
