Fake. You can siphon water, but not pump it higher than the highest point of the water in a container. It's likely this video is fake... probably gay too.
That is exactly what a "Ram pump" does. They do work too. You have "waste water" so that is not ideal but it works.
I didn't mention it because setup is gay. It requires a very specific situation. I prefer gasoline, personally. It's simple, reliable and works no mater where the liquid is. A simple hand pump also works well. Oh, let's not forget buckets. I used them often to "pump" water out of my boat. Often, gallons at a time.
Ram pumps only work when source body of water is flowing. Not really "very specific" but a certain circumstance indeed. Water can be pumped up hill quite a distance with a decent body of flowing water.
