For Class A storage tanks buried directly underground, how should the drainage system be designed? All the pipe openings are above the storage tank, while the drain pipe opening must be below, buried. As for how this is handled in practice, I’m not very familiar with it; I would appreciate advice from those with experience.
Only pumping or vacuum suction can be used.
What I know is that it isn’t discharged outside; it stays in the tank. For example, the underground oil tanks at gas stations – are those classified as Category A? The oil outlet has a slope, so the oil will flow back by gravity. Please give more points.
Refer to the gasoline tank at the bottom of the gas station! ! !
