it all relates to pressure if it’s from the top it all floods, but if it happens near the bottom of the tunnel it won’t flood much more than the water pressure allows.
I don’t know if this has been brought up, but if they put water in I would love to maybe irrigate. Like you layout the buildings , but with water so if you wanted a river going through your city and you could put a bridge go over it. Like this.
Water was discussed here and there. The search-function reveals some interesting hits which might be a good starting point to enter an existing discussion:
However, no specific discussion yet about bridges I think 
.
just a quick cross post comment from @sdee on water:
We’re withholding water until we have a better sense of how we want it to work gameplay-wise. We don’t want it to just be aesthetic.
Have another suggestion for gameplay.
To go along with hunger, what about thurst?
Everyone needs water.
You could collect buckets of water from a water source near by or by building a well that could be in the middle of your village/ city square.(just like picking berries)
Water could also be used by crafters too:
weavers to make dyes
Masons to make bricks and cobblestone.
blacksmiths to help forge weapons and armour
Magma-smiths can use water to cool and solidify magma when making whatever it is they will craft.
Brew-masters will definitely need it to create delicious ales
any thoughts on this concept?

well with idea with everyday use of water theres problem of disease Health Care (Classes) / Disease and plagues but nobodies actually said to use it for crafting like better smithing ale solidifying magma dyes cement etc.) but this idea is good and can easily be developed on
indeed! will just quote my earlier quote here…

well done @GeorgeCrecy! you “corrected” a few things i hadn’t intended to be corrected… 
but you did indeed knock out the required items… +2 internet points for you!
i summon @Swift_Cube!
I came here in his place, he’s a bit… indisposed of at the moment. 
Sir yes sir! My internet legions are at your command!

To take this thread back to topic, I personally love water systems. Everything about pipes, pumps, watergates, fountains, dams. I think a lot of this can be realised without breaking too much of the theme.
well, the good news is, Radiant already has designs for full irrigation systems to (among other things) aid in the farming process (if the player chooses to get a little more hands on in that area)… 
Pff, farming. I want water powered contraptions. Elevators. Furniculars. Perhaps even dip into electricity a bit.
There’s nothing that says “power” like having giant 50m tall gates that open magically with hydraulics. Also, they could crush enemies.

should you not be as inclined to get digital dirt under your nails, take comfort in knowing that the framework for irrigation systems will be in place for farming… which means they can be stolen/reworked to apply elsewhere… should be relatively trivial for someone with your talents…

If it were me I would make it so that water “flows in” or is Regenerated at a specific rate. (ie; the river flows in from the north edge of the map and brings 20,000 gallons per “minute,” or the well can produce 10 gpm.) However it would then flow back out if allowed. (So in essence water would be infinite over time yet finite at any singular moment.) In this way a well of course would fill up to a max and then stop (as wells do) while a river from the north would just drain out to the south unless dammed.
Being able to dam the water would also be a good thing as long as it was done well. puting in a dam should not just stop the water and allow for drawing. Water needs to have volume, if you dam a river it should start flooding the area around the river behind the dam. Which means that if you put it in the wrong place it could flood your city or mine or the river might shift and take another rout and suddenly your dam is useless for anything but shifting the river.
As far as the “Cycle” goes, you really only need about half. Evaporation for the water cycle, snowmelt and all those other things are fairly unimportant to a game that does not take into account the full global world. What is needed is;
- How much water volume flows in with the river,
- How fast water seeps into the ground (and whether or not there is a limit)
- How fast will our citizens be using said water,
- How far from the water source will irrigation be effective,
- Will rain have an effect on water seepage, irrigation, or water levels.
- Will there be system for water pressure (pumps, volumes, and gravity)
When dealing with the end product of the water (ie: sewage) is another system entirely that would be handled under the disease mechanics. After all any sewage that can’t be handled by the water seepage system is most likely solid.

The main problem here is that every more-than-simple implementation of water gets calculation intense rather quick (Terraria is a good example; although it caps the calculations it does per frame its simulation can either take forever or breaks completely).
How is Dwarf Fortress dealing with water? If I remember correctly it was similar to Minecraft in the sense that it had 8 levels of water or something?
