Shallow Tank Module Quantity Calculator

Estimate modules and single-layer footprint from a geometric void-storage target. Use a designer-approved requirement as your starting input.

Basis and limits

Each module occupies 0.5 m² and has a 95% void ratio. Quantity rounds up to whole modules. This excludes unused depth, access components, operating water levels, perimeter clearance and project allowances; it does not certify effective detention capacity or loading.
