40d:Well

Wells must be built over the water. Though they can be many levels higher than the water.

Wells are structures that serve as water sources for your dwarves. Dwarves will drink from wells if there is no alcohol to be found in your fortress, and your dwarves would rather drink from a well than from a river or pond. Wells may be constructed as long as the well has a clear vertical pathway to a water source, i.e. an aquifer, an underground reservoir, an aboveground water source (if you built the well inside a house that's above water), or an underground river, brook, stream, or lake.
