How to Decide What Kind Of Rainwater Tank Rain Water Tank Is Most Optimal For Melbourne, Vic

There aren’t many consolations to a rainy day– cosy lounge time, soothing sounds of drops 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 volume of stormwater runoff into rivers and oceans, and can also reduce your water tanks perth bill in the longer term.

Rainwater tanks are no more just huge, round and ugly; they are available in all sizes and shapes that can make efficient use of minimal or tricky urban spaces.

Water for outdoor or indoor use?

The absolute most important issue to consider before you purchase 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, as an example– is the most convenient way to start, as you possibly just need the supplier to set up the water tank, rather than a licensed plumber. And it will immediately cut your usage of mains water.

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

What size rain water tank do I need?

The volume you choose will be dependent on the size and shape of your household and garden. Round, squat tanks fit efficiently 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, 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 appropriate for you, sellers often provide calculators on their websites, or your water authority may have the opportunity to help.

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

Materials

Rainwater tanks commonly come in the following materials:

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

Polyethylene (plastic) tanks are well-known as they are reasonably cheap and durable. Because rust isn’t a conern, 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 work 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 created to withstand extreme temperature levels. They’re not the cheapest possibility, and better for above-ground installation, while all other styles can also be installed below ground.

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

Regulations

Ask your local area council and water supplier which rules and regulations apply in your region. You may need to submit 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 refurbishing, building new or retrofitting?

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

Extra expenditures

When getting quotes, ask if there are any further costs for delivery and installation; extra components (such as pipes, fittings and taps); alternative extras (such as a first-flush or backflow-prevention device); a pump (unless you can make use of 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 consider the cost of special ground prep or excavation).

If you would like to connect the tank to your mains water supply, look into the cost of a licensed plumber, and expenses for any additional work that needs to be done to your roof and/or guttering.

Can you get a water tank rebate?

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

Cost

Rainwater tanks can range 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.
