Bad water blocks

[SilverSpeedy]

I notice on the some of the Bad water techs are different between the 2 races. Folk beavers to block bad water spread, only blocks bad water. The same item for Ironteeth blocks water and bad water spread. Iron teeth blocks do not seem as good as Folk blocks. Folk blocks seems to block more bad water spread than Iron teeth. For longer bad tide events with Iron teeth, bad water blocks makes harder to control bad water tides around fresh water sources. I had 2 areas were Iron teeth beavers got sick from ground spread without touching bad water. I try to line bad water river with bad water blocks (Iron teeth) but still have spread in areas that should not have. Has anyone else notice this?

Don't have any screenshots, but perhaps you have diagonals? Last patch made it so badwater blockers must be orthoganal.
That's the fastest diagnostic, the other is that the bad water blocking blocks are XY axis only, so if badwater flows OVER a block, it will spread to an adjacent block. There may be a location where the water level dips over a blocker periodically.

You can see the block in what it says and shows the area blocks are built but bad water spread is beyond the blocks.

The image you posted is correct because both contaminated and clean water sources can spread through soil blocks in a chain reaction. To completely cut off the contamination, you need to isolate a piece of land that is not affected.

1. The difference between Iron Teeth and Folktails is intended. As Foktails are close to nature, they would invent such a filter solution while Iron Teeth would simply get the water for irrigation from somewhere else with their superior pumps.

2. Infection with badwater form ground pollution is impossible for beavers (plants die of course). Either your beavers got infected elsewhere or the stream overflows from time to time and your beavers get wet feet.

3. The behavior in your screenshot is as intended. Pollution spreads 8 blocks inwards, also around corners (imagine walking block by block). You can count it in your screenshot on both sides.

i disagree with the superior pumps. the folktails big water pump is a lot more effective than the IT pump, however the IT pump can reach much deeper, but with sluices that advantage also get less

Iron teeth mechanical pumping is much better, in conjunction with the actually useful water wheels.

As said by jacobs but blocks no longer work diagonally In the experimental update 7. They have to be edge to edge.
Agree with trixi the FT pump has a depth of 4 (IIRC) and produces 15 per hour for a crew of 3. Incredible output.
