 ### ADD BEAUTY AND VALUE WITH A RANGE OF COLOURS.

When it comes to water tanks, many people worry that large wooden rain barrels or ugly metal cisterns may affect the market value, of their home. It does not have to be this way. Orion Water Tanks have carefully developed a range which reflects Tasmania’s character. Our tanks are beautiful, carefully designed with aesthetics in mind, and with plenty of colour options to blend in with the Australian landscape.

### DURABLE CONSTRUCTION

Our water tanks are manufactured from Food Grade UV stabilised polyethylene, which makes them tough, durable and able to withstand the harsh Australian sun.  
Do not rust or corrode, and are impact resistant—a long term and worthwhile investment.  
Single piece moulded construction ensures long term structural strength.
