When sewer lines become obstructed, the thick, black water that forms as sewage is a health hazard, and is extremely unsanitary as it contains contaminants such as pathogens, bacteria, and viruses that can present a risk of severe illness if exposed to people or pets. If you have a sewage backup in your basement, or your toilet has backed up, you will need to fix it quickly, or you will end up with dirty water all over your floors. Knowing what causes sewer backups, however, may help you prevent a hazardous occurrence in your basement, home or business. Here’s a list of items that may help to prevent and handle sewage backups:

Sewage Backup Causes

  • Heavy Rainfall – Excess rains can overpower your town or city’s storm sewer system. If this happens, the water can back up into the attached sewer lines placing your home or business in possible risk of water backflow. Increasing rivers and streams, hurricanes and other similar events can cause flood and sewage waters to blend and present serious health related dangers. You should be highly cautious when walking in this type of water, and even stay cautious after the water recedes and dries up. It’s viable for the organic matter to be aerosolized and respirable, meaning there’s a chance you could inhale it into your lungs. To prevent contact or risk of breathing in these contaminants, proper PPE should be worn at all times.
  • Tree Roots – Trees can have long roots that grow into water or sewer lines and crush or break them. Damage to pipes and a sewer backup can also be caused by tree roots that aren’t even on your land. Be acutely aware of any tree roots that can reach your water and sewer lines that lead to the central sewer line or septic system.
  • Old/Aging Sewer Pipes – Older and aging sewage structures are susceptible to breaking down and cracking, inducing sewer backups, flooded basements as well as entire home flooding. The older your area or home may raise the chance of this type of damage occurring.
  • Clogged and Blocked Drain Pipes – If your home or business’s main sewer line or drain pipes become blocked, sewage may back up inside the dwelling. A fine example is: if a single toilet causes a sewage backup, the adjacent pipes connected to that toilet, or the main drain lines of more toilets, will also suffer backflow flooding.
  • Old and/or Damaged Lines – Older sewage systems have a propensity to suffer damage and crumble, leading to sewer water influx and flooded dwellings full of sewage. If your home or area is older, the probability is greater that you’ll experience damaged sewer lines than newer ones.
  • Copious Rainfall – Heavy and rapid rainfall can overpower your local storm sewer lines rapidly. If these public sewer lines can’t deal with excess waters, water can backup and flow into connected sewer lines. This can put your home or business at risk of backflow problems. Regional flood waters from events like surging rivers and creeks, hurricanes, or any rainy weather events can cause clean water to merge with sewage water and other chemicals and harmful toxins that cause serious health difficulties. Use extreme caution when moving on foot in this type of water, but also stay cautious when it dries. The dried organic matter can turn aerosolized and turn respirable. Correct PPE needs to be used at all times to prevent contact and risk inhaling polluted air.
  • Blocked/Clogged Pipes – A clogged pipe or sewer line can cause sewage to back up into your home or business. If only one toilet becomes fouled, the sewage backup can spread on to the sewer lines and influence all linked toilets on that line.
  • Roots from Trees – Tree roots can cause damage to water and sewer lines. The roots from huge trees can maneuver into and around the lines and damage them tremendously. If the roots under your property are not the cause, roots from closely located trees can grow under property lines and harm your sewer line, causing a sewage issue. Be extra aware of all tree roots near your mainline sewer pipes and/or pipes leading to your septic tank.
