Underground Storage Quantity Estimator
Enter the storage volume your engineer has already calculated for the finished tank. The estimator returns a purchasing count: ARW-1050 units, 40 ft containers, cargo net weight and the footprint your chosen number of layers would occupy. It does not size storage and it is not a design tool.

—What this count is built on
- ARW-1050 at 500 mm height and 95% void: 237.5 L storage per complete unit, 9.8 kg per complete unit. The 400 mm height version holds 190 L and is not used in this calculation.
- ARW-1050, 500 mm: 237.5 L nominal storage per complete unit; approximately 1,340 units per 40 ft container. The 335 m³ loading reference is assembled exterior volume, equivalent to approximately 318.25 m³ of nominal void storage. Unit and container counts are rounded up; final packing follows the ordered configuration and accessories.
- Footprint is your unit count divided by two units per square metre, then divided by the layers you entered. The layer count is your input, not our recommendation.
- Cargo net weight is the goods only. A verified gross mass also includes packaging, dunnage and the container, and is stated separately.
- Storage volume is a quantity of storage. It is not a pollutant-removal or water-quality figure, and cover depth, load grade and drain-down remain your engineer’s decisions.
