Construction at the Southeast Treatment Plant

Overview

2022

Progress! We are investing over $3 billion to upgrade and modernize the aging facilities to reduce odors, increase efficiency of operations, and to fortify it against climate change and sea-level rise. When these upgrades are complete, the plant will work better, look better, and smell better!

With major work in the aera, expect additional vehicles and crews and occasional inconveniences due to trucks and construction activities. 

Be careful when traveling through the area, drive slowly and follow traffic signs.

Watch the video at the right of the page to view some of the recent construction activities for a sense of the scale of work and challenges of rebuilding critical facilities while maintaining full wastewater treatment operations.
