Sewage Backup Cleaning: Safe Wastewater Cleanup

Sewage backups can involve untreated wastewater that poses health risks, as sewage may contain disease-causing bacteria, viruses, and parasites. As noted by specialists like Floodline Restoration Co., effective sewage backup cleaning requires strict protective protocols, controlled extraction, and thorough disinfection.^[2]

According to the U.S. Environmental Protection Agency (EPA), between one-third and two-thirds of U.S. sanitary sewer collection systems have problems involving sanitary sewer overflows (SSOs) or excessive peak flows at wastewater treatment plants. Major causes of these overflows include blockages, wet-weather infiltration, and mechanical or electrical failures. These overflow events can discharge untreated sewage into streets, private property, basements, and receiving waters, and SSOs can close beaches. In a 2004 report, the EPA estimated that 23,000 to 75,000 SSO events occur annually, discharging approximately 3 billion to 10 billion gallons of wastewater each year, though these figures exclude sewage backups into buildings. Furthermore, national overflow totals may be underreported because some events are not reported to federal or state environmental agencies.^[1]

3. Avoid electrical hazards: Avoid standing water where electricity may be present, and shut off power only from a safe location.
4. Notify relevant parties: Contact the utility and your insurer.
5. Document and arrange cleanup: Document damage without entering unsafe areas, and arrange qualified cleanup and disinfection.
