What is the largest available size in the concrete underground tank. Can you set them up with a firefighting reserve. Is there a discount for purchasing more than one.


  • Posted by G Store on Monday, 17 March 2014
    52,500 litres is the largest available, but it is a very deep hole so a lot of people will go with multiple 20000 or 30000 litre tanks. Yes we often do a firefighting reserve. Let us know what you need and where the property is and we will give you our best price.
