There aren’t many consolations to a rainy day– cosy couch time, soothing sounds of water on the roof, and maybe a rainbow or a puddle-splash afterwards. But you can add another by placing a water tank to capture a portion of that downpour: it will reduce your environmental footprint by reducing your demand on mains water and the quantity of stormwater runoff into rivers and oceans, and can also cut your water bill in the long term.
Rainwater tanks are no longer just huge, round and hideous; 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 application?
The absolute most important issue to consider before you get and install a rainwater tank is how you wish to use the water.
Employing the water outdoors– for watering the garden and washing the car, for example– is the fastest way to start, as you probably just need the supplier to install the rainwater tank, instead of 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 hot water system, but you’ll need a licensed plumber to connect the rainwater tank to your mains supply.
What size tank do I require?
The capacity 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 are good for narrow spaces. An underfloor tank or bladder storage system is a good out-of-sight space saver, but is more expensive.
Your roof area and the annual rainfall in your area will also need to be considered. To help determine the size and shape that’s best for you, sellers often provide calculators on their internet sites, or your water authority may have the opportunity to help.
What else do I need to recognize before buying a rain caravan water tanks tank?
Rainwater tanks usually can be found in the following materials:
Metal tanks are manufactured from corrugated or flat rolled metal, which can be galvanised or coated. They often come with a plastic inner lining (Aquaplate) that will enhance the life of the tank and give protection to the water quality.
Polyethylene (plastic) tanks are well-liked as they are relatively cheap and durable. Because rust isn’t a conern, they are a pretty good option for people living near the ocean. Other synthetic materials, such as PVC and geotextile, are utilized 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 manufactured to withstand extreme temperatures. They’re not the cheapest choice, and more suitable for above-ground installation, while all other styles can also be set up below ground.
Concrete tanks, often used for agricultural and industrial applications, won’t rust, burn, melt or blow away. They can be bought ready-made, or custom made onsite.
Ask your local council and water supplier which rules and regulations apply 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, as well as restrictions on the tank’s location, colour, height and labelling or noise regulations for a pump.
Are you remodeling, building new or retrofitting?
If you are remodeling or building, rather than retrofitting, you may need to incorporate energy and water-efficient functions in your plans to obey new legislative requirements.
When getting quotes, inquire if there are any additional 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 employ gravity for water pressure); and a stand (unless you wish to put it on the ground or below it, by which case you’ll need to factor in the cost of special ground prep or excavation).
If you want to connect the tank to your mains water system, look into the cost of a licensed plumber, and costs for any supplementary work that needs to get done to your roof and/or guttering.
Can you acquire a water tank rebate?
Talk to 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, 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.
