Water for outdoor or indoor use?
Easily the most important issue to consider before you purchase and install a rainwater tank is how you would like to use the water.

Save even more by sending the water to your toilet, washing machine or hot water system, but you’ll need to have a licensed plumber to connect the tank to your mains supply.
What size tank do I need?
The volume you choose will depend on the size and shape of your household and garden. Round, squat tanks fit well 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.

What else do I need to recognize before getting a rain water tank?
Rain water tanks commonly come 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 boost the quality of life of the tank and protect the water quality.
Polyethylene (plastic) tanks are well-known as they are relatively cheap and durable. Because rust isn’t a conern, they are a good option for people living near the coast. 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 durable, it’s not intended for outdoor installation.
Fibreglass tanks are rust and chemical-resistant and designed to withstand extreme temperatures. They’re not the cheapest possibility, and preferable for above-ground installation, while all other styles can also be set up below ground.
Concrete tanks, more often used for agricultural and industrial purposes, won’t rust, burn, melt or blow away. They could be bought ready-made, or customized onsite.

You may need to forward a development or building application, and there may be policies around drinking rainwater or mosquito breeding prevention, as well as restrictions on the tank’s specific location, colour, height and labelling or noise regulations for a pump.
Are you remodeling, building new or retrofitting?

When acquiring quotes, ask if there are any further costs for delivery and installation; extra products (such as pipes, fittings and taps); optional 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, through which case you’ll need to look into the cost of special ground prep or excavation).
If you want to connect the tank to your mains supply of water, think about the cost of a licensed plumber, and costs for any additional 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 rebate or bill reduction– the answer may depend on the size of the water tank and Recommended Webpage whether it’s connected to a toilet and/or washing machine.
