Water tanks generally can be found in the following materials:

Metal tanks are made from corrugated or flat rolled metal, which may be galvanised or coated. They often come with a plastic inner lining (Aquaplate) that will enhance the life of the tank and safeguard the water quality.

Polyethylene (plastic) tanks are prominent as they are reasonably cheap and durable. Because rust isn’t an issue, 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 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 temps. They’re not the cheapest option, and more suitable for above-ground installation, while all other types 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 can be bought ready-made, or customized onsite.


Ask your regional council and water supplier which rules and regulations are applicable in your local area. You may need to provide a development or building application, and there may be regulations around drinking rainwater or mosquito breeding prevention, together with restrictions on the tank’s specific location, colour, height and labelling or noise regulations for a pump.

Are you refurbishing, building new or retrofitting?

When securing 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 use 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 think about 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 prices for any extra work that needs to get done to your roof and/or guttering.

Get in touch with 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 rain water tank and whether it’s connected to a toilet and/or washing machine.
