Sewer has backed up in my basement. Who do I call?
Notify the Water & Wastewater Department at (302) 366-7000. Once notified, the City will dispatch the sewer truck to check the main sewer line in the street for blockages. If the main is clear, it is the homeowner's responsibility to call a plumber. The City suggests that all homeowners install a backflow preventer or plug in the floor drain to prevent potential backups in the event the main is blocked.
