That's fair, I did notice more murky water when scavenging. I suppose it is hard for me to adjust due it shifting how the game works. I'll have to look into the filter and collectors. The problem is likely my play style, I'll usually scavenge a bunch and gather resources, then I'll go work on building the base and defenses for awhile. I like building so I make BIG bases. Like currently I'm fortifying the hospital in diersville.
Normally I'd grow stuff to eat and then drink waters, filling up at lakes when necessary, so I could keep building.
