When a sewer line is obstructed, the sewage that is thick and dark is dangerous to your health. This sewer waste is extremely unsanitary, containing contaminants such as bacteria, viruses and pathogens. All of these contaminants can pose a serious health danger and cause many illnesses if humans or animals are exposed. If it happens that you experience sewage backup on the property of your home or business, or a toilet backup in either location, repairing either one is of the highest importance. Having this filthy sewer waste in your home is not safe and should be removed quickly. Furthermore, knowing what is causing the sewer obstruction may aid in preventing this potentially hazardous incident. To help you in managing sewage backups in your home or business, following is a list of things that can help:

Causes of Sewage Backup

  • Clogged Sewer Line – Sewage backs up into your home or business when your drain lines or main sewer lines become blocked. To present an example: if one toilet starts a sewage backup, the connected drain and/or many toilets and the main line may become blocked.
  • Imposing Tree Roots – Trees that have large strong imposing roots have the potential to grow into and around pipes, even demolishing sewer pipes. Tree roots are able to extend out to a long distance and damage your pipes, leading to a sewer backup. Be very aware of roots near your main sewer lines or septic tank area to protect them from damage.
  • Aging & Damaged Sewer Lines – Older sewer lines, pipes, drains and septic systems can fail by slowly weakening and failing over time – leading to sewage backups, water filled homes, and basements full of sewage. Pay attention to the age of your home and surrounding area and search for these potential problems.
  • Heavy Rainfall Amounts – Heavy amounts of rain can overcome your main storm and sewer lines. If it happens that your public system can’t handle large rainfall amounts, the flooding can make its way into the sewer lines linked to the mainline, and place your home or business in a possibly dangerous exposure of sewer backup. There is a risk of serious health issues when in and around flooding waters in your region that happens from flooding in rivers and streams, hurricanes, and other related weather, when water blends with sewage, contaminants and chemicals. When wading in this waste use extreme caution, and also when the water recedes and starts drying. Organic substance that is dried out can then convert to be aerosolized and present a risk of breathing in these contaminants. Be positive to use proper PPE to guard against these dangerous risks.
