Sewer backups and overflows are typically the result of grease buildup which can cause property damage, environmental problems and other health hazards. The easiest way to solve grease problems and help prevent overflows is to keep fats, oils and grease out of the sewer system. Never pour grease down sink drains or into toilets.
A Dewatering Permit application must be filed for certain discharges to the Commission's wastewater or storm drainage systems. It is necessary to research BWSC's wastewater maps to determine whether the discharge is to a sanitary sewer, combined sewer or storm drain.
