There aren’t many consolations to a rainy day– cosy lounge time, soothing sounds of water on the roof, and possibly a rainbow or a puddle-splash afterwards. But you can add one more by installing a water tank to capture a portion of that downpour: it’ll reduce your environmental footprint by lowering your demand on mains water and the volume of stormwater runoff into rivers and oceans, and can also reduce your water tanks melbourne bill in the long run.
Rainwater tanks are no more just huge, round and uninviting; 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 most important issue to consider before you acquire and install a water tank is how you would like to use the water.
Applying the water outdoors– for watering the garden and washing the car, for instance– is the best way to start, as you probably just need the supplier to install the water tank, instead of 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 require a licensed plumber to connect the 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 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 internet sites, or your water authority may have the ability to help.
What else do I need to understand before getting a rain water tank?
Rainwater tanks generally can be found in the following materials:
Metal tanks are created from corrugated or flat rolled metal, which can 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 well-liked as they are comparatively cheap and durable. Because rust isn’t an issue, they are a very good option for people living near the coast. Other synthetic materials, such as PVC and geotextile, are applied for bladder storage. Bladders are useful for water storage below a deck or floor; while their material is durable, it’s not intended for outdoor installation.
Fibreglass tanks are rust and chemical-resistant and manufactured to withstand extreme temperature levels. They’re not the cheapest solution, and better for above-ground installation, while all other styles 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 may 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 submit a development or building application, and there may be guidelines around drinking rainwater or mosquito breeding prevention, in addition to restrictions on the tank’s specific location, colour, height and labelling or noise regulations for a pump.
Are you renovating, building new or retrofitting?
If you are restoring or building, in lieu of retrofitting, you may have to incorporate energy and water-efficient attributes in your plans to obey new legislative requirements.
When acquiring quotes, inquire if there are any supplementary 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 would like to put it on the ground or below it, in which case you’ll need to think about the cost of special ground prep or excavation).
If you want to connect the tank to your mains supply of water, consider the cost of a licensed plumber, and charges for any supplementary work that needs to be done to your roof and/or guttering.
Can you obtain a water tank rebate?
Talk to 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 tank and whether it’s connected to a toilet and/or washing machine.
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 basing on the size, material, finish and strength of the tank.
