So I have a question about water pressure. If I have a vertical U bend with a river such that water on the left size is at Z-0 and the water on the right side is Z-1 (i.e one level lower because the river isn't dammed (see: http://dwarffortresswiki.org/index.php/v0.34:Pressure#Water_in_a_U-Bend). Can I force water into the right side at Z-0 somehow? I was wondering if I put water on the left side with a pond designation if it would cause the pressure to equalize then keep the right hand side pressurized at Z-0?

Or to put it another way if I have a vertical U bend and one side is providing infinite water, but only naturally pressured to Z-1 will the other side continue to fill with water at Z-0 if it's already partially filled with water pressured to Z-0?

Why not use a pump somewhere?

Why not use a pump somewhere?

I'd prefer a more minimal solution + one that leaves the "entrance" to require swimming up into a U bend. I'll add pumps if I need to, but I'd rather leave it as a small unpowered solution. Why build pumps if dumping a little water would get the whole thing to work.

I'm also curious for science. As I've seen actually the opposite where 'seeding' water has prevented water pressure. My situation for that was this:

Water tank at Z-0 supplied by aquifer
at Z-1 There is a Door at a corner. When the door is closed the only path by is a diagonal (resets pressure). When opened the water flows without a diagonal (keeps pressure)
Platform of downstairs at Z-0 over a pit of water at Z-1 (filled from water tank)

If I open the door (via lever) when the platform is dry pressure causes the platform of downstairs to fill with water (and fast!). However if the platform isn't dry (1/7 or 2/7 water and the door is opened the pressure doesn't appear to transfer. Or at least that was my observation and could be other causes.

Well... what you're describing doesn't really sound to me like it's going to work, but then I don't claim to be educated. At best, the bucket-dumped water will stay on the surface there, at worst, it'll sink and teleport to the river. Setting up a little bucket brigade can't be too tough for this, so feel free to try.

Yes, the answer to any Dwarf Fortress question is always Science. But in this case, you're not going to be able to make water go higher than it wants without pumps, I'm pretty sure. You can hide them somewhere if it really bothers you aesthetically.

Yeah, you'll need a pump. What you're suggesting would just overflow the intake pond.

That said you can still leave a water entry if you have two pipes, one with a pump and one not. The pressure in a water system (without diagonals) is equal to the greatest pressure in the system. Though this may also overflow your intake pond.
