New Overflow or Bypasses Regulation - Regulations that address reporting and
public notification regarding sewage overflows and wastewater treatment plant
bypasses became effective on March 28, 2005.
The Maryland Reported Sewer Overflow Database contains combined sewer
overflows (CSOs) and the sanitary sewer overflows (SSOs) reported to the
Maryland Department of the Environment (MDE) from January 2005 to the present.
MDE updates this database weekly. Although MDE requires that all public sewer
system owners or operators report overflows to us, there may be incidents that
were not reported. Note that overflow amounts provided by the person reporting
the overflow may be estimated using best professional judgment or they may be
actual readings from flow measurement devices when available.
If you have any questions about this database, please contact Mr. David
Lyons, Mr. Jesse Salter or Mr. William Lee at 410-537-3510.
