LOL, the concept is sound but the equipment is asking for a disaster, especially when we are trying to avoid flooding at all cost
Preventing flooding is not something related to the used material as long as it is water tight.. Tho what's used in the video aslo would'nt be my choice it indeed looks all a bit to wimsy, i would go for stackable hard pvc crates/boxes and build something in simular concept.. A sump if calculated and constructed corectly should have no risk of flooding.. The pump should never pump out more water than the tank or pond can take if the drainage stops and the level of drainage should never be more then the volume of the sump. Calculating the volumes visa versa is all to it.. That's not a diy but more a math skill.
