When sewer pipes become blocked, the thick, black water that forms as sewage is a health risk, and is extremely unsanitary as it contains contaminants like pathogens, bacteria, and viruses that may pose a risk of extreme sickness illness if exposed to people or animals. If you have a sewer backed up in your basement, or your toilet backs up, you will need to repair it quickly, or you will end up with dirty water all over your floors. Knowing what causes sewer backups, however, may help you avoid a hazardous situation in your basement, home or business. Here’s a list of items that may help to prevent and deal with sewage backups:

Sewage Backup Causes

  • Clogged Drain Pipes – Sewage backs up into your home or business when your drain pipes or main sewer pipes become blocked. To present an example: if one commode starts a sewage backup, the connected drain and/or numerous toilets and the main line may become clogged.
  • Imposing Tree Roots – Trees with large strong long roots have the potential to grow into and around pipes, even crushing sewer pipes. Tree roots have the capability to reach a long distance and wreak havoc on your pipes, causing a sewer backup. Be very aware of roots near your main sewer lines or septic tank area to prevent damage.
  • Aging & Damaged Sewer Lines – Aging sewer lines, pipes, drains and septic systems can fail by slowly cracking and crumbling over time – resulting in sewage backups, water filled homes, and basements full of sewer water. Pay attention to the age of your home and community and look out for these potential problems.
  • Large Rainfall Amounts – Large amounts of rain can crowd your main storm and sewer mains. If it happens that your public sewers can’t handle large rainfall levels, the flooding can make its way into the sewer lines linked to the mainline, and place your home or business in a possibly dangerous possibility of sewer backup. There is a risk of serious health issues when in and around rising waters in your town or city that happens from flooding in rivers and streams, hurricanes, and other related weather, when water blends with sewage, impurities and chemicals. When wading in these waters use extreme caution, and also when the water decreases and starts drying. Organic matter that is dried out can then turn aerosolized and present a threat of breathing in these contaminants. Be positive to use proper PPE to guard against these dangerous risks.
