Yes, field trips were always my favorite part of school. The "How its Made" show scratches a similar itch.

I've noodled with the idea of starting a "fieldtrips for grownups" group but I feel like a wastewater treatment plant is more likely to open their doors for a group of third graders than a group of thirty somethings.

That’s probably true but I wouldn’t count it out. I think you’re more likely to get answers like “we do 10:00 on tuesdays” (timed for schools) than “no”

That is a great idea. Too often, we just grow up getting used to the idea that things are just made somewhere in a "black box" and never take the time to investigate. We could probably get into more places than we realize.

The Oakland wastewater treatment plant offers tours open to the general public: https://www.ebmud.com/wastewater/collection-treatment/wastew...

Wouldn't be surprised if others do as well, or would be willing to if you asked the right person nicely.

Probably true. Usually. Just keep your eyes on local news, and wait 'till the Sewer Dept. is facing budget cuts, or needs a rate increase to pay for long-delayed repairs, or is trying to get a millage passed.
