Market Terminology Translator

One modular tank is sold under five names across five markets. If you are sourcing for more than one country, you are reading several vocabularies for the same product. Pick the term on your drawing and this returns what it is called elsewhere, what physically changes between them, and what does not.

Priority column follows the runoff destination hierarchy in England’s national standards for sustainable drainage systems, which applies to England. Elsewhere it reads as a design sequence rather than a rule. The modules, the moulded dimensions and the load grades are identical across all five rows — what changes is the wrap, the outlet arrangement and the word on the drawing.
