Storage Volume → Module & Container Calculator

Enter the water quality volume (WQv) or design-storm storage volume from your site’s stormwater calculation. This tool converts that number into module count, excavation footprint, and shipping containers using Storm Manager’s published 95% void ratio and 1.05× excavation multiplier — the same figures shown in the spec table above.

Basis: 95% void ratio, 1.05× excavation multiplier, and 330 m³/40HQ container are the figures published in the spec table and logistics section above — not project-specific engineering. Confirm final module count and layout with an application engineer before ordering.
