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

There aren’t many consolations to a rainy day– cosy sofa time, soothing sounds of drops on the roof, and possibly a rainbow or a puddle-splash afterwards. But you can add one more by building a water tank to capture some of that downpour: it’ll reduce your environmental footprint by reducing your demand on mains water and the amount of stormwater runoff into rivers and oceans, and can also reduce your water bill in the long-term.

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

Water for outdoor or indoor usage?

The absolute most important issue to consider before you get and install a rainwater tank is how you would like to use the water.

Utilizing the water outdoors– for watering the garden and washing the car, for example– is the easiest way to start, as you possibly just need the supplier to install the tank, as opposed to a licensed plumber. And it will promptly cut your usage of mains water.

Save lots more by sending the water to your toilet, washing machine or hot 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 hinge 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 have to be considered. To help determine the size and shape that’s suitable for you, sellers often provide calculators on their internet sites, or your water authority may be able to help.

What else do I need to know before investing in a rain water tank?

Materials

Water tanks usually can be found in the following materials:

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

Polyethylene (plastic) tanks are well-known as they are fairly cheap and durable. Because rust isn’t a conern, they are a pretty good option for people living near the coast. 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 strong, it’s not intended for outdoor installation.

Fibreglass tanks are rust and chemical-resistant and designed to withstand extreme heat levels. They’re not the cheapest choice, and more suitable for above-ground installation, while all other kinds can also be installed below ground.

Concrete tanks, often used for agricultural and industrial reasons, won’t rust, burn, melt or blow away. They might be bought ready-made, or julianhefner534.weebly.com customized onsite.

Regulations

Ask your local area council and water supplier which rules and regulations are applicable in your location. You may need to provide 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 renovating, building new or retrofitting?

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

Extra expenses

When securing quotes, inquire if there are any additional 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 utilize gravity for water pressure); and a stand (unless you would like to put it on the ground or below it, in which case you’ll need to factor in the cost of special ground prep or excavation).

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

Can you acquire a water tank rebate?

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

Cost

Rainwater tanks can fluctuate from around $700 to $2000, starting from 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.
