When sewer lines become blocked, the thick, black water that forms as sewage is a health danger, and is extremely unsanitary as it consists of contaminants such as pathogens, bacteria, and viruses that may pose a risk of severe 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 fix it quickly, or you will end up with sewage all over your home or business. Knowing what causes sewer backups, however, may help you avoid a hazardous situation in your basement, home or business. Following is a list of items that may help to prevent and handle sewage backups:

Sewage Backup Causes

  • Drain Pipe Blockages – Sewage can infiltrate your home or business when either your drain pipes or the main sewer line becomes clogged. For example, if one commode creates a sewage backup, the drain leading to that toilet, or the mainline of many toilets, will likely also be clogged.
  • Tree Roots – Trees with large roots can move into pipes and cause holes or alter the sewer line by growing around it. Even if the roots in your yard are not the problem, roots from nearby trees can reach your sewer line and damage it, forcing a sewer backup. Always be aware of roots where your sewer lines to the street or septic system is placed.
  • Damaged Sewer Lines – Aging sewage systems can break down and crack, causing sewage blockages and flooded homes and basements. The older your neighborhood is, the greater chance of these types of issues.
  • Extreme Weather – Heavy amounts of rain can overburden your area’s storm sewer lines. If the public systems can’t handle large amounts of rainfall, the water can make its way into connected sewer lines, which can leave your home or business at risk of water backflows. Area-wide flooding waters from events such as rising rivers and streams, hurricanes, and other micro events can also combine with sewage waste and other chemicals and contaminants that can cause health-related issues. Extreme caution is needed when wading in these waters, and even when the flood recedes and begins to dry out. Dried up organic matter can then become aerosolized and become respirable. Proper personal protective equipment (PPE) should be worn to avoid contact and the danger of breathing in these contaminants.
