What is a sewer overflow?
A sewer overflow is a discharge of raw sewage mixed with storm water into local waterways. Overflows occur when there is too much wastewater for the sewer system or treatment plants to handle, such as after heavy rainstorms. To relieve pressure in the system and minimize backups into homes and businesses, excess sewage is sent into local waterways. State and federal regulations require MSD and sewer agencies across the country to reduce overflows and meet Clean Water Act requirements.
