Despite the recent storm, the summer has been unusually dry. Rains are inevitable in the Chicago region, so the Metropolitan Water Reclamation District of Greater Chicago (MWRD) is reminding residents how they can prepare for storms to prevent or minimize basement flooding and sewer backups.
The Chicago metropolitan area developed on a flood plain. During heavy rain storms, the open land was able to absorb excess water. As the region grew with construction of commercial and residential buildings and expanses of paved surfaces, the area was less able to absorb rainwater.
