Join us for a hauntingly good time!
Come celebrate Halloween with an educational twist at our third annual Trick or Treatment event! Enjoy trick-or-treating at tables hosted by local environmental and community organizations while learning about wastewater treatment.
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!

Time: 10 a.m.-2 p.m.
