How to drain water?
« on: June 25, 2011, 08:00:44 am »

I've always wandered how the water can be drained away from the map.
I just created a drowning passage, but once full I don't know where to put that water. I can just punp it in the open so it can evaporate, but I don't want my map to become muddied.
How can i drain the water then? By dumping it into the fist cavern layer? By pumping it at the border of the map?

By the way, I have acces to a river.

If you don't mind cheaty way, use bridge to atom-smash the water.

You can atom-smash liquids? wow.
But I think it's a little difficult to design and it will take forever to "annihilate" so much water.

Nah, I build atom smashers in any watertower, magmatower or other structures (on the lowest level, grated off so dwarves won't go there), and it is very fast. Just assign a pull lever job with repeat.

Dump it to a cavern that reaches the map edge.

You have a river anyway, you could dump the water there to flow off the map edge.  Its going to roll around on top of the river a lot and flood the banks downstream though.  If your cavern water is connected to a map edge you can do the same thing there, the little flooding before draining should be less noticeable.

A classic way is to just route it down a passage to any map edge and turn the final tiles into fortifications (since you cant dig the edge tile anyway)

Also if you have an aquifier they can absorb unlimited water

I wish I had something cool to say about this.  Because it's really cool.

The fortification at the edge seems a good idea, I thought you can't do anything at the edge tiles.

If you do this, it's a good idea to dig down a couple of levels and add extra layers of fortifications, to speed the draining process.

In version 0.31.xx, water can pressure-path off the edge of the map (including via fortifications), so the width doesn't really matter unless you're simply allowing it to flow out naturally.

P.S. If you don't get this note, let me know and I'll write you another.
It's amazing how dwarves can make a stack of bones completely waterproof and magmaproof.
It's amazing how they can make an entire floodgate out of the bones of 2 cats.
