DF Dwarf Mode Discussion / How do I filter my cistern?
« on: February 23, 2012, 06:29:00 pm »
So back in v34.01 I made a cistern in a fort. In the (1 square wide) tunnel that connected the river to the cistern, I placed a Grate, Fortification, Grate, right next to each other.
Or was it Fortification, Grate, Fortification? I forget. Anyway...
I remember reading that this would prevent things from getting into my cistern, keeping it animal/monster free. That's exactly what I wanted. Then I pulled the lever to fill the cistern and...
...watched as a swarm of fish spawned inside of it.
Now I'm building another one in 34.02, and I'd like to build a filter for it.
So... how do I keep my cistern and underground water supplies free of animals/creatures/vermin/monsters/whatever?
