There aren’t many consolations to a rainy day– cosy couch time, soothing sounds of drops on the roof, and perhaps a rainbow or a puddle-splash afterwards. But you can add yet another by attaching a water tank to capture some of that downpour: it’ll decrease your environmental footprint by minimizing your demand on mains water and the volume of stormwater runoff into rivers and oceans, and can also reduce your water bill in the long run.
Rainwater tanks are no longer just huge, round and bad-looking; they come in all shapes and sizes that can make efficient use of modest or tricky urban spaces.
Water for outdoor or indoor usage?
Easily the most important issue to consider before you get and install a water tank is how you wish to use the water.
Applying the water outdoors– for watering the garden and washing the car, for instance– is the simplest way to start, as you possibly just need the supplier to install the rainwater tank, as opposed to a licensed plumber. And it will instantly cut your utilization of mains water.
Save much more by sending the rainwaer to your toilet, washing machine or hot water system, but you’ll need to have a licensed plumber to connect the rainwater tank to your mains supply.
What size rain water tank do I really need?
The volume you choose will hinge on the shapes and size of your household and garden. Round, squat tanks fit well 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 location 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 be able to help.
What else do I need to know before acquiring a rain water tank?
Rain water tanks generally are available in the following materials:
Metal tanks are created from corrugated or flat rolled metal, which can be galvanised or coated. They often incorporate a plastic inner lining (Aquaplate) that will enhance the quality of life of the tank and protect the water quality.
Polyethylene (plastic) tanks are well-liked as they are reasonably cheap and durable. Because rust isn’t a problem, they are a very good option for people living near the ocean. Other synthetic materials, like PVC and geotextile, are utilized for bladder storage. Bladders are useful for water storage below a deck or floor; while their material is strong, it’s not intended for outdoor installation.
Fibreglass tanks are rust and chemical-resistant and created to withstand extreme temps. They’re not the cheapest alternative, and preferable for above-ground installation, while all other kinds 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 might be bought ready-made, or custom made onsite.
Ask your community council and water supplier which rules and regulations are applicable in your area. You may need to forward a development or building application, and there may be regulations around drinking rainwater or mosquito breeding prevention, together with restrictions on the tank’s location, colour, height and labelling or noise regulations for a pump.
Are you refurbishing, building new or retrofitting?
If you are refurbishing or building, instead of retrofitting, you may need to incorporate energy and water-efficient attributes in your plans to abide by new legislative requirements.
When obtaining quotes, inquire if there are any further 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 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 would like to connect the tank to your mains water system, look into the cost of a licensed plumber, and charges for any extra work that needs to get done to your roof and/or guttering.
Can you get a water tank rebate?
Get in touch with your local water or government authority to see if you’re entitled to a cash rebate or bill reduction– the answer may hinge on the size of the water tank and whether it’s connected to a toilet and/or washing machine.
Rainwater tanks can vary from around $700 great post to read $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.
