23rd Annual Open House

Thank you, Pittsburgh! Nearly 1,700 visitors joined us for our biggest celebration of clean water yet.

From exploring our new outfall to meeting Frankie the Fish, taking the PUP Pledge and diving into hands-on science, our guests made it an unforgettable day.

Relive the day in our 2025 recap video.

Thank you for making this year's Open House a tremendous success! We hope you learned about what we’re doing through our Clean Water Plan and enjoyed exploring the Plant Tours. We always enjoy showing our littlest scientists how wastewater treatment works and watching them soak it all up through our engaging activities. Everyone’s enthusiasm and participation are truly appreciated! Check out some pictures of this and previous years’ Open Houses below.
