There aren’t many consolations to a rainy day– cosy sofa time, soothing sounds of drops on the roof, and maybe a rainbow or a puddle-splash afterwards. But you can add yet another by building a water tank to capture a bit of that downpour: it’ll shrink your environmental footprint by minimizing your demand on mains water and the quantity of stormwater runoff into rivers and oceans, and can also slash your water bill in the long-term.
Rainwater tanks are no longer just click the up coming article huge, round and ugly; they are available in all shapes and sizes that can make efficient use of small or tricky urban spaces.
Water for outdoor or indoor application?
The absolute most important issue to consider before you purchase and install a water tank is how you intend to use the water.
Using the water outdoors– for watering the garden and washing the car, for example– is the fastest way to start, as you possibly just need the supplier to install the rainwater tank, instead of a licensed plumber. And it will instantly cut your consumption of mains water.
Save much more by sending the rainwaer to your toilet, washing machine or water system, but you’ll need a licensed plumber to connect the rainwater tank to your mains supply.
What size water tank do I need to have?
The volume you choose will rely on the shapes and size of your household and garden. Round, squat tanks fit efficiently 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, but is more expensive.
Your roof area and the annual rainfall in your area will also have to be considered. To help determine the size and shape that’s suitable for you, sellers often provide calculators on their sites, or your water authority may have the ability to help.
What else do I need to recognize before investing in a rainwater tank?
Rain water tanks usually come in the following materials:
Metal tanks are created from corrugated or flat rolled metal, which might be galvanised or coated. They often feature a plastic inner lining (Aquaplate) that will increase the life of the tank and safeguard the water quality.
Polyethylene (plastic) tanks are well-known as they are fairly cheap and durable. Because rust isn’t a problem, they are a 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 durable, it’s not intended for outdoor installation.
Fibreglass tanks are rust and chemical-resistant and created to withstand extreme temperatures. They’re not the cheapest possibility, and preferable for above-ground installation, while all other styles can also be installed below ground.
Concrete tanks, more frequently used for agricultural and industrial functions, won’t rust, burn, melt or blow away. They can possibly be bought ready-made, or custom made onsite.
Ask your regional council and water supplier which rules and regulations apply in your area. You may need to provide a development or building application, and there may be regulations around drinking rainwater or mosquito breeding prevention, in addition to 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 restoring or building, rather than retrofitting, you may need to incorporate energy and water-efficient elements in your plans to fulfill new legislative requirements.
When obtaining quotes, ask if there are any additional costs for delivery and installation; extra materials (such as pipes, fittings and taps); alternative 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 wish 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 would like to connect the tank to your mains water system, consider the cost of a licensed plumber, and costs for any supplementary work that needs to be done to your roof and/or guttering.
Can you access a water tank rebate?
Contact your local water or government authority to see if you’re entitled to a cash discount 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 vary from around $700 to $2000, beginning with 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.
