Plum Island Construction - Phase III

Work is currently underway on Phase III of a major construction project at the Plum Island Wastewater Treatment Plant. Phase III is part of a $61 million capital renovation project out at Plum Island.

About the project

This phase will create new headworks and wastewater clarifiers. New technology in the form of an anoxic selector basin is also being installed. This new basin changes how we treat wastewater by creating an “anoxic zone.” The basin will improve our treatment process now, but it also enables us to meet any new regulations in the future.

The sewer project is an important part of how we carefully plan for the future. Through projects like these, we remain poised to handle the rapid growth and development of our area for generations to come.

During Construction

During construction, residents near the plant will notice increased construction traffic. We will have multiple truck loads of concrete delivered to the plant to aid in the project. Due to multiple factors, some of these loads will be delivered between the hours of midnight and 6:00 a.m. We will notify the neighborhood by placing signs at the entrance before these deliveries are made. We have also reminded the construction company to slow down and minimize noise during these late night deliveries.


We anticipate this project to be complete by late 2018.

We appreciate the community's patience as we work to improve our system.
