Do not drink waste water

I made a trip over to Sweetwater Wetlands/Refuge to get some bird photography in this past weekend. There wasn’t much happening over there. I saw a few ducks and a couple of cranes, but other than that, there weren’t a lot of birds.

On my way out, I saw this sign and thought to myself why would anyone want to drink from waste water?? I guess a better question would be, did somebody already drink from the water and now they have to post signs?
