SATURDAY, SEPTEMBER 15th Open House and Clean Water Fest


From trucks to tours to treats, our annual Open House gets bigger and better every year. And you are the reason why.


Literally thousands of guests show up on a fall Saturday every year to learn more about where their water goes and what they can do to keep our Great Lake great. Our Open House is a celebration of community and all things water as we open the doors of our Southerly treatment plant and our laboratory facilities for a day of education and entertainment.

FEATURED EVENT: Register for one of three bike tours of our Southerly treatment plant! Space is limited!

The third Saturday of September is designated as our Open House Saturday. From 9:00 a.m. until 4:00 p.m., guests are free to visit more than 60 exhibitor booths, meet our employees and local partners, tour our award-winning wastewater treatment plant and lab, sit in our trucks and operate our equipment, see live entertainment and so much more.
