- Liquid volume of tanks (other than the Largest Tank) above Fdn upto Dyke Ht: ...
- Dead Volume of Fire wall = 0.2 X 0.6 X (56 + 199+ 77.5 + 77.5 + 77.5 + 77.5 + 77.5) = 77.1 M3

Is standard for dyke wall?

Separation distances between the nearest tanks located in separate dykes shall not be less than the diameter of the larger of the two tanks or 30 meters, whichever is more. Process equipment should not be located inside the dyke.
How is spill containment calculated?
- Length (L') x Width (W') x Height (H') x 7.48 = Sump Capacity (Gallons)
- L x W x 2'H x 7.48 = 520 gallons.
- L x W x 14.96 = 520 gallons.
- L x W = 520/14.96 = 34.76.
- So any combination of L x W >= 34.76, where L > 5.5 and W > 3.5 will work.
