Why can Pawtucket’s sewers back up?

Combined sewers

The Narragansett Bay Commission says the sewers in Pawtucket and Central Falls are combined sewers, carrying sanitary sewage from homes and businesses plus stormwater from streets and buildings. In heavy rain they can become overwhelmed and overflow into the Seekonk River.

Overflows and blockages

The NBC says its system uses combined sewer overflows to send excess storm flow to local rivers so that used water does not back up into homes and businesses. It also says pipes can become blocked by debris such as trash, rocks and disposable wipes, or by grease, which can cause sewer backups.
