Capacities and footprints we typically install
Every TankSmith tank is built to your footprint, not ours. Panel modularity means we can fit a 100 m³ tank into a 4 m × 2.5 m × 10 m strip if that's all you have.
| Capacity | Common Application |
|---|---|
| 5–20 m³ | Small commercial backup, single floor of restaurant or clinic |
| 50–100 m³ | Mid-size warehouse fire reserve, mid-rise condominium potable |
| 100–250 m³ | Large warehouse, factory process water, school campus |
| 250–500 m³ | Industrial cooling-tower make-up, hospital potable + fire combined |
| 500+ m³ | Large factories, mall fire reserve, LGU bulk storage |
