Rainwater Tank Tips for Residents

The type of tank you choose will depend on your site, how much water you need and your personal preferences. There are a number of different types of tanks on the market:

·         Traditional, round, above-ground rainwater tanks are usually the cheapest type of prefabricated tanks per litre of volume and require a properly formed concrete slab for support.

·         Slim-line tanks may be installed along a fence or at the side of your home. They usually need a properly formed concrete slab for support, depending on their height relative to their width.

·         Storage walls are very slim modular slim-line tanks (typically plastic) that lock together to fit into tight spaces. They are generally the most expensive above-ground tank type.

·         Underground tanks save on space and can potentially hold more water than above-ground tanks. However, this option requires excavation. There is also a requirement for a pump, which may not be needed for above-ground tanks. It should be noted that underground tanks are usually much more expensive than the above-ground tanks.

·         Bladders are sealed flexible sacks that are suitable for subfloor spaces which have as little as 600 mm height clearance. While their installation is more technically involved than a standard tank, they can be a good solution when renovating where space is limited. They are usually more expensive than a standard above-ground tank and may require a registered plumber to install
