Peirce Island Wastewater Facility Upgrade Project

This project is the largest that the City has undertaken. The Peirce Island Wastewater Treatment Facility (WWTF) upgrade expands treatment at the plant to an advanced secondary process which removes organics and nitrogen. Progress videos are available on our YouTube page, shown below.

NOTICE: A routine inspection of the Peirce Island Bridge will take place on Monday, November 25. For more information, click here.
