Flooded Basement in Mill Basin: What You Need to Know

Basement flooding in Brooklyn is overwhelmingly caused by two things: combined sewer overflow (CSO) during heavy rain and failed sump pumps. In pre-war buildings, below-grade units have no waterproofing membrane — water migrates through the foundation walls via hydrostatic pressure. CSO events push Category 3 (black water) sewage into basements, requiring full hazmat-level extraction, antimicrobial treatment, and demolition of all porous materials that contacted contaminated water. Modern sump pump systems with battery backup are the single most effective prevention measure.
