Thanks for all the advice everyone! You all are making this game truly enjoyable! I built on an aquifer so I thought it was an aquifer, the place i dig down in is 7/7 deep water deep and I get this area is too dangerous to dig. What should I do?
1. First, chops much wood, build a carpenter's workshop.
2. Make 4 wooden blocks, 4 wooden pipe sections and 4 enormous wooden corkscrews.
3. dig a 3x3 hole in the aqifer:
0000000000
000~~~000
000~~~000
000~~~000
0000000000
4. it's the level above the aquifer, 0 is flat ground and ~ is a channeled tile.
5. Build an up/down staircase from above this level:
0000000000
000~~~000
000~X~000
000~~~000
0000000000
6. Construst 4 screw pumps in a crescent around the hole and dig channels directly behind them
00000~000000
00000^000000
00000| 000000
0000~~~00000
0~<-~X~->~00
0000~~~00000
00000| 0000000
00000V0000000
00000~0000000
-> indicates a pump pumping from west to east.
7. Have 4 dwarves operate pumps.
8. Order your other 3 dwarves to build an up/down staircase directly under your existing staircase:
#######
##000###
##0X0###
##000###
#######
This is the level below. # stands for damp aquifer wall, and 0 is flooded floor or ramp. Your four working pumps should keep the area dry enough to work.
You _will_ get job suspensions, but hust ignore them and unsuspend your work.
9. After the staircase is complete, order 4 pillars(walls) built in the corners:
#######
##W0W##
##0 X 0##
##W0W##
#######
W stands for wall.
10. after they are ready, order the walls between them:
### # ###
##WWW##
##WX W##
##WWW##
########
12.
11. Profit! It's complete, you can now deconstruct your pumps and dig further down.
