What Causes Sewage Backups & How To Clean Up Sewage

What Causes Sewage Backups in Lafayette Buildings?

Sewage backups are stressful, hazardous and require specialized cleanup. Sewage backup can also damage floors, furniture and promote mold development if not dealt with properly. Let’s take a closer look at what causes sewage backups in the first place and how to handle cleanup when it occurs.


Sewage Backups Caused by Clogged Sewer Lines:

Clogged lines are the most common cause of sewage backups in commercial and residential properties. Your pipes can become clogged when excess toilet paper, grease, food, hair, dirt, and small objects get sent down the drain and collect to create a blockage.  Blocked lines can slow down (or stop) the flow of wastewater through your plumbing system, causing it to come back up. Clogs are frequently caused by the misuse and abuse of your sewage lines, as well as a lack of adequate maintenance. Keep an eye on your drains. If you have many drains clogged at the same time, it could be a symptom of a larger problem with your main sewer system. You should get expert help as soon as possible to resolve the problem.


Damaged or Broken Sewer Lines Cause Sewage Leaks:

Debris settling, age-related wear and tear, tree roots, external damage, and pebbles and dirt entering the pipes can all cause a sewage line to crack or break. This causes a blockage in the line, which might result in sewage backing up into your home. When a sewage line breaks or completely collapses, wastewater will stop flowing to its destination. This can cause sewage stay in the pipe and eventually back up into the home. Whether your sewer line is damaged or completely collapsed – you need to consult a professional plumber to properly repair the issue.  


Tree Roots Damage Sewer Lines & Cause Sewage Backups:

Tree roots are infamous for their tenacity and viciousness. Tree roots can extend several feet underground from the tree itself. Roots can grow into or around sewer lines in various circumstances. This can result in holes, obstructions, or even complete failure. The issue with trees is more than meets the eye. You can never tell what trouble is hiding beneath the surface of an iceberg. Even if no trees are planted close or above your sewage pipes, roots from surrounding yards might intrude on your line and cause problems.


Health & Safety Hazards of Sewer Leaks

Sewer backups can cause serious property damage and present certain health & safety risks. “Black water” or Category 3 water can damage building materials, cause structural concerns, and present certain health risks due to the heavily contaminated wastewater.



  • Health & Safety Hazards: Wastewater from a sewage leak usually contains a variety of bacteria, viruses, and germs that can be hazardous to humans. If you do not take the necessary safety precautions when dealing with a sewer leak or backup, you can be putting yourself and your family at risk.
  • Property Damage & Structural Concerns: Raw sewage and wastewater can leave you with serious and costly property damage if it is not properly cleaned up in a timely manner. Porous building materials may be non-salvageable after contamination. If the property is not properly dried out, you might end up with serious structural concerns later down the line.
  • Fire Hazards: If the water level has reached any plugs, electrical outlets, extension cords, or gas-burning equipment, do not touch anything! Get out of the building immediately and call the professionals as the risk of a fire is enormous. If all your electrical equipment as well as the distribution panel is still safely above water, switch off the power as soon as you detect the problem.

Sewage Removal, Sanitization & Deodorization

Lafayette homeowners should not attempt to remove and cleanup raw sewage on their own. The wastewater from a sewer backup can contain dangerous bacteria and harmful contaminants. Cleaning up sewage water is considered a Category 3 water cleanup because is it grossly contaminated can contain pathogenic, toxigenic, or other harmful agents. Cat 3 water cleanups should be performed by water restoration professionals who are properly equipped and experience in the safe handling and removal of raw sewage. All contaminated areas need to be thorough sanitized and noxious odors need to be eliminated to ensure restoration of a clean and safe environment.


For you and your family’s safety, sewage cleanup should be completed by a trained professional who will be able to properly complete the following:


  • Safely extract any sewage water
  • Carefully remove any non-salvageable, sewage-contaminated belongings and building materials
  • Properly complete an effective structural dry out
  • Thoroughly sanitize & deodorize the affected areas to restore safe conditions for you and your family.

However, they also come with specific vulnerabilities concerning water intrusion that can lead to significant damage if not addressed promptly. Hidden Threats Beneath Concrete Foundations Slab homes in Louisiana are particularly susceptible to hidden water damage. Under-slab leaks can occur when pipes beneath the concrete begin to deteriorate. This situation can go unnoticed for long periods, allowing water to seep into the ground and compromise the structural integrity of the home. Mold growth is another concern, thriving in moist conditions often created by leaks. Given Louisiana's humid climate, early detection of these leaks is crucial to preventing extensive damage and costly repairs. Why Slab Homes Are Especially Vulnerable in Louisiana The unique geographic and climatic conditions of Louisiana heighten the risk of water damage in slab homes. Heavy rainfall can lead to water accumulation around and beneath foundations. Given the state's high humidity , this increases the potential for moisture intrusion. Additionally, poor drainage in many areas exacerbates the problem. Without proper grading and drainage systems, water can pool near foundation walls, leading to further risks of foundation damage. The combination of these factors creates an environment where slab foundations can suffer significant structural issues. Early Warning Signs of Water Intrusion Homeowners should be vigilant for several early warning signs of water intrusion in slab homes. Common indicators include wet spots on floors , especially near walls, which may point to underlying leaks. Cracks in walls or floors are another critical sign that a slab foundation may be compromised. If doors and windows become difficult to close, this could be due to shifting foundations caused by moisture issues. Regular inspections can help catch these problems early, ensuring that necessary measures can be taken to protect the home's structural integrity. Environmental and Geological Challenges in Louisiana Louisiana's unique geological characteristics present significant challenges for homeowners. The combination of a high water table, expansive clay soils, and flood-prone areas creates a complex environment for slab foundations prone to water intrusion. High Water Table and Heavy Rainfall Louisiana often experiences a high water table due to its geographical conditions. Prolonged heavy rainfall can cause groundwater levels to rise significantly, leading to water accumulation under slab foundations. The moisture can exert pressure on the slab, causing cracks and other structural issues. Residents must recognize the need for proper drainage systems to manage excess water. Water intrusion can exacerbate mold growth and health risks, highlighting the importance of addressing these factors proactively. Impact of Expansive Clay Soils The soil in many regions of Louisiana is predominantly clay, known for its capacity to expand and contract with moisture changes. When saturated, clay can swell, pushing against slab foundations. Conversely, as it dries, it shrinks, potentially creating voids beneath the slab. This cycle leads to uneven settling and structural instability. Homeowners must be aware that water management strategies are crucial to minimize the impact of clay soils on their foundations. Regular inspections and moisture control measures can help maintain integrity. Flood-Prone Areas and Soil Movement Many areas in Louisiana are susceptible to flooding, given the state's flat terrain and proximity to water bodies. Flooding can result in significant soil movement, destabilizing foundations. The movement can be subtle but damaging over time, leading to potential safety hazards.  It is essential for homeowners in these areas to invest in flood-resistant designs and construction methods. Understanding the risks associated with soil movement and taking preventive measures can protect against severe damage. Proper landscape management and drainage systems play a critical role in reducing these risks.

By taking proactive measures and being aware of the signs of water intrusion, they can maintain a healthy living environment and protect their property from the detrimental effects of Louisiana's unique climate. Understanding Louisiana’s Climate and Its Role in Water Damage Louisiana's climate significantly influences water damage risks in residential properties. The state's high humidity levels and frequent rainfall create ideal conditions for moisture accumulation , which can lead to severe structural issues when not properly managed. Unique Challenges of High Humidity and Frequent Rainfall High humidity is a defining characteristic of Louisiana's subtropical climate. This moisture-laden air can often hover at 60% or higher, creating an environment where water damage becomes a pressing concern. Frequent rainfall compounds this issue. Heavy downpours can overwhelm drainage systems, leading to localized flooding and pooling water. This additional water increases the chances of leaks developing in roofs, basements, and plumbing systems. Small leaks that may seem inconsequential can rapidly escalate. When combined with persistent humidity, they create an environment where mold thrives , exacerbating both health risks and damage to property. Impact of Subtropical Climate on Moisture Control Louisiana's subtropical climate results in a long growing season, which is beneficial for agriculture but detrimental in terms of moisture control. Warm temperatures combined with high humidity levels hinder effective drying of surfaces and materials after rainfall or spills. Building materials such as wood and drywall absorb moisture easily. Over time, this leads to deterioration and increases the risk of mold growth. Conventional methods for controlling moisture may not suffice in an environment where excessive humidity is the norm. Maintenance strategies must be proactive. Using dehumidifiers, ensuring proper ventilation, and regularly inspecting homes for vulnerabilities can significantly mitigate moisture-related issues. How Excess Moisture Sets Louisiana Apart In Louisiana, excess moisture is not just a seasonal inconvenience; it is a year-round challenge. The risk of water damage increases substantially due to the combination of high humidity and the state's geographical features, like bayous and wetlands. These factors create a unique water cycle, where humidity levels often remain elevated even when it’s not raining. As a result, water damage can occur not just from direct leaks or flooding but also from the continual exposure to moist air. Homeowners need to remain vigilant. Regular monitoring of areas prone to dampness, along with prompt repairs, can help prevent small issues from escalating into significant water damage problems. How Humidity Accelerates Water Damage from Leaks In areas characterized by high humidity, even minor leaks can lead to significant water damage. The constant presence of moisture in the air exacerbates the effects of these leaks, leading to greater structural challenges over time. Escalation of Damage in Constant Moisture Conditions High humidity creates an environment where water damage can escalate rapidly. When a leak occurs, the excess moisture already present in the air prevents effective drying. This prolonged exposure can lead to serious issues such as mold growth , characterized by visible water stains and potential health risks. As the humidity remains elevated, the risk of structural damage increases. Wood and other materials absorb moisture, resulting in warping and weakening. Over time, this deterioration can compromise the integrity of the building. Compounding Effects of Small Leaks Small leaks may initially seem insignificant, but they can have compounding effects under high humidity. The moisture introduced by these leaks can quickly raise indoor humidity levels, creating a cycle of persistent dampness. For example, a leaky faucet or a small crack in a pipe can release water into areas that remain moist due to surrounding humidity. As moisture builds up, mold and mildew thrive in these conditions. These growths not only damage surfaces but also contribute to poor indoor air quality. Detecting leaks promptly becomes crucial to mitigate these compounded effects before they escalate into larger problems. Persistent Moisture and Material Deterioration The interaction between humidity and leaks leads to persistent moisture problems that affect various building materials. For instance, drywall and insulation readily absorb excess moisture. This not only leads to visible damage like water stains but can also create hidden risks behind walls.  Constant moisture leads to deterioration that may require extensive repairs or replacements. Replacing rotted wood beams or damaged drywall can be costly and time-consuming. Regular inspections and maintenance are essential to identify and address leaks early, helping to preserve the structural integrity of the home. By managing humidity levels, property owners can significantly reduce the risk of severe water damage.
