It goes without saying that a sewage backup is unpleasant. Wastewater stinks, is filled with things best left unmentioned and poses significant contamination and biohazard risks in addition to all of the other problems that can be caused by regular flood waters. Even more so than normal water damage, sewage backups need to be cleaned up and their damage restored as soon as possible, regardless of whether it is a toilet flooding or a septic backup.
Sewage backups are a form of (usually) basement flooding that happens for one of two broad reasons: either a sewage or septic line becomes clogged so waste goes the other way, or some structural element is allowing the water to enter your home. Within these two categories include the following causes:
- An improper object has been flushed down the toilet.
- Pipe blockage or leakage.
- Foundation flaws that allow for water infiltration.
- Weather-induced flooding around the home.
- Defects in the septic system or structure.
