Attention boys and ghouls!

Do you want to celebrate Halloween while you learn about the environment and get to do fun activities? Look no further! Our Trick or Treatment event is guaranteed to thrill!

Trick-or-treat your way around tables hosted by local environmental organizations, learn about wastewater treatment and the environment, and have a chance to take a tour of a real wastewater facility. Trust us-it's cool!

Costumes are optional but encouraged! Please refrain from any costumes that may be seen as offensive or include a weapon.

All goblins and ghouls are welcome!
