How To Understand Which Watertank Is Most Suited For Melbourne, Vic
There aren`t many consolations to a rainy day-- cosy sofa time, soothing sounds of water on the roof, and maybe a rainbow or a puddle-splash afterwards. But you can add yet another by placing a water tank to capture some of that downpour: it will shrink your environmental footprint by reducing your demand on mains water and the amount of stormwater runoff into rivers and oceans, and can also cut your water bill in the long run.
Rainwater tanks are no longer just huge, round and ugly; they can be found in all shapes and sizes that can make efficient use of modest or tricky urban spaces.
Water for outdoor or indoor usage?
The most important issue to consider before you buy and install a rainwater tank is how you want to use the water.
Employing 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 set up the rainwater tank, rather than a licensed plumber. And it will immediately cut your consumption of mains water.
Save a lot 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 tank do I need to have?
The volume you choose will be dependent on the size and shape of your household and garden. Round, squat tanks fit well 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, although 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 right 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 identify before investing in a rain water tank?
Water tanks typically can be found 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 increase the quality of life of the tank and protect the water quality.
Polyethylene (plastic) tanks are well-liked as they are comparatively cheap and durable. Because rust isn`t a problem, they are a good option for people living near the ocean. Other synthetic materials, such as PVC and geotextile, are applied 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 manufactured to withstand extreme temps. They`re not the cheapest solution, and more suitable for above-ground installation, while all other types can also be set up below ground.
Concrete tanks, more frequently used for agricultural and industrial applications, won`t rust, burn, melt or blow away. They could be bought ready-made, or custom made onsite.
Ask your community council and water supplier which rules and regulations are applicable in your location. You may need to forward a development or building application, and there may be rules around drinking rainwater or mosquito breeding prevention, together with restrictions on the tank`s placement, colour, height and labelling or noise regulations for a pump.
Are you renovating, building new or retrofitting?
If you are renovating or building, rather than retrofitting, you may have to incorporate energy and water-efficient components in your plans to satisfy new legislative requirements.
Extra costs
When obtaining 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 make use of gravity for water pressure); and a stand (unless you would like 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 wish to connect the tank to your mains water supply, look into the cost of a licensed plumber, and costs for any extra work that needs to be done to your roof and/or guttering.
Can you access a water tank rebate?
Consult your local water or government authority to see if you`re entitled to a cash grant or bill reduction-- the answer may rely on the size of the 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 basing on the size, material, finish and strength of the tank.
