I don't think so, because the well diameter all the way down is like 40 cm, and the water head in the well is at around 15m deep. So apparently no way to suck more than 10.5 meters, and no way also to make many steps since no access to an intermediate point below the opening of the well.

The application of such a system would definitely be essential where economical electrical power to drive a modern well pump is either unreliable or unavailable. But it's not my case. I have 24/7 electricity and a fair enough solar system and lithium batteries. I also have a submersible pump...

The water will be used for household. I need like 100 liters per hour. (Approximate daily consumption being 2400 liters). I thought the difference of energy would come from the difference of weight between the water inside the pipe and the water inside the barrel. But it shows there are other...

My scenario consists of using negative pressure. First step is filling the barrel by a the big amount of water (85 liters). The barrel has two connections: • one in the top for the pipe going down to the well. • another one at the bottom to let the water out of the barrel to a water tank...

[Mentor Note: Thread moved from the schoolwork forums to the technical forums, since it appears to be a real-world problem] If I have a water well 55m deep I want to suck water by gravity without any pump. I put a barrel of 85 liters and connect it firmly to a pipe of 55m length going into...
