You have like 9 water pumps going. Your population could be supported on half of that. That's 4 jobs freed up at least

Happy Thursday! You can turn off the water pump that was pumping the water out of the flooded area. Not sure if you want to turn on the fluid pump. With the flood gates you can always just open them and let the water flow into the lake. @10:33 You may want to beef up the dividers for when you flush out the bad water. Some are almost overflowing now and that is without the 20 something bad water flowing through. You will probably have to do both the levees and the land. That will be a ton of water flowing and you have to combine the other flow too. I hope this makes since. Thanks for sharing :)

You need to double the height of your retaining walls

You need somewhere for the badwater to Go at the top. You need to blast out a back way before the new floodgate wall can work. And those platforms in front should be 2 high to keep their feet dry (no contamination).

wouldn't it be better to have bad water pumps surrounding the bad water sources so it's not diluted by fresh water? You'd probably get better efficiency then.

Day 500 of recommending putting water wheels down the right hand side of the map where you're forcing all the water to flow. Then you can open the caps of the 2 bad water sources during droughts for power.

I think your damn isnt tall enough it needs to be taller than bad water/goodwater sources
