NSW Rainwater Tank Specifications

Built to Last

All Coolamon Concrete Tanks are built to the highest specifications and are fully engineer-designed. 

At the very minimum, our tanks are designed to comply with the relevant Australian Standards which include:

AS3600 – Concrete Structures, AS1379 – Ready Mixed Concrete, AS1302 – Deformed Bars, AS1304 – Welded Fibre Fabric, AS3610 – Formwork for Concrete,

AS3735 – Concrete Structures Retaining Liquids

We have many different Tank designs, from the basic passenger vehicle load to a super heavy-duty W8 (8 tonnes per wheel) load. We can have a Tank designed to meet any load requirements or specific uses.

Because of the proprietary information contained in our Engineer Drawings, they are not published on this website. However, we are happy to supply our full Engineer Drawings upon request.
