The present is clean. The future is cleaner.

The Narragansett Bay Commission’s (NBC) Combined Sewer Overflow project, known as RestoredWaters RI, is Rhode Island’s most significant clean water project. Phases I and II of the project were completed in 2008 and 2014, respectively, and are responsible for dramatic improvements in water quality in upper Narragansett Bay and Providence’s urban rivers.

Started in spring 2021, Phase III of the project is a 2.2-mile long tunnel approximately 125 ft underground that will collect and transport storm-related sewage overflows to NBC’s Bucklin Point wastewater treatment facility for treatment before entering open waterways.

Please continue to check back with us, as the site will be updated regularly throughout the project.
