There aren’t many consolations to a rainy day– cosy couch time, soothing sounds of water on the roof, and possibly a rainbow or a puddle-splash afterwards. But you can add another by installing a water tank to capture a bit of that downpour: it’ll diminish your environmental footprint by reducing your demand on mains water and the volume of stormwater runoff into rivers and oceans, and can also trim your water bill in the long-term.
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 modest or tricky urban spaces.
Water for outdoor or indoor usage?
The absolute most important issue to consider before you buy and install a water tank is how you would like to use the water.
Utilizing the water outdoors– for watering mouse click the next webpage garden and washing the car, as an example– is the most convenient way to start, as you probably 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 even more by sending the rainwaer to your toilet, washing machine or water system, but you’ll require a licensed plumber to connect the water tank to your mains supply.
What size tank do I need to have?
The capacity you choose will be dependent on the shapes and size 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, however, is more expensive.
Your roof area and the annual rainfall in your region will also have to be considered. To help determine the size and shape that’s ideal 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 purchasing a rain water tank?
Water tanks commonly are available in the following materials:
Metal tanks are manufactured from corrugated or flat rolled metal, which might be galvanised or coated. They often include a plastic inner lining (Aquaplate) that will increase the quality of life of the tank and give protection to the water quality.
Polyethylene (plastic) tanks are prominent as they are comparatively cheap and durable. Because rust isn’t a problem, they are a good option for people living near the sea. Other synthetic materials, like PVC and geotextile, are used for bladder storage. Bladders work 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 developed to withstand extreme temperatures. They’re not the cheapest choice, and preferable for above-ground installation, while all other kinds can also be installed below ground.
Concrete tanks, more often used for agricultural and industrial intentions, won’t rust, burn, melt or blow away. They might be bought ready-made, or custom made onsite.
Ask your regional 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, along with restrictions on the tank’s placement, colour, height and labelling or noise regulations for a pump.
Are you remodeling, building new or retrofitting?
If you are renovating or building, as opposed to retrofitting, you may have to incorporate energy and water-efficient characteristics in your plans to adhere to new legislative requirements.
When securing quotes, ask if there are any supplementary 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 want 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 intend to connect the tank to your mains supply of water, factor in the cost of a licensed plumber, and charges for any supplementary work that needs to get done to your roof and/or guttering.
Can you acquire a water tank rebate?
Get in touch with your local water or government authority to see if you’re entitled to a cash grant or bill reduction– the answer may depend on the size of the rainwater tank and whether it’s connected to a toilet and/or washing machine.
Rainwater tanks can vary 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.
