sewage bypassing

Heavy rains and flooding has forced more than three dozen communities in north central and northeast Iowa to release untreated sewage into nearby streams and rivers, according to the Iowa Department of Natural Resources (IDNR).

Resident living near those communities with private wells for drinking water are being cautioned by the IDNR about using those sources.

The rain and the resulting flooding caused overflows to a total of 37 wastewater treatment plants, forcing the facilities to bypass treatment to prevent backups of sewage into homes and businesses.
