How do you penetrate aquifers? cause that's the real reason i took them out rofl. But without collapsing as I know that works already.
Ways I know of to get past aquifiers
1) get lucky with multiple biomes or non porous mineral deposits to allow a water free path to deeper layers
2) Drop natural walls into a channeled out pool to form a water proof section you can tunnel through
3) Pumps to drain out a small area and masons to smooth the newly exposed walls so they no longer produce water
4) Channel out a pool, fill with magma.
5) Drain into another aquifer.
6) Channel out a pool, expose to freezing tempratures, Channel and construct a way through the ice.
That being said i'm not quite skilled enough to deal with multiple layer aquifers with any level of confidence, I'm not a fan of them but won't leave a embark just because of a 1 layer aquifer. I'd probably be a lot more comfortable with them if there was a reliable way of getting stone on aquifier maps without having to breach your first season.
