Sewage is Category 3 black water and a health hazard, so avoid all contact with sewage and contaminated water. This guide covers heavy rain and basement flooding in general terms, for Florida homes where basements are rare and slab-on-grade construction dominates. A basement that stays damp after the standing water is out still needs drying, because the moisture in the walls and floor has not left.

Your Next Step
