Every home or business using a municipal sewer system is susceptible to sewage backups. Knowing the causes and effects of a sewage backup can help property owners take preventive measures to mitigate the risks.

### Causes of Sewage Backups

**1. Clogged Drains:**
– Grease, hair, and other debris accumulating in drains and pipes can impede water flow, leading to blockages and backups.

**2. Tree Root Intrusion:**
– Tree roots penetrate sewer lines through cracks or broken joints, causing clogs and damaging the pipes.

**3. Heavy Rain:**
– Excessive rainfall can overwhelm sewer systems, causing overflows and backups in homes.

**4. Sewer Line Damage:**
– Deteriorated or damaged sewer lines from age, corrosion, or external factors can result in leaks or backups.

**5. Blockages in the Main Sewer Line:**
– Debris, grease, or other large objects can clog the main sewer line, disrupting the flow and causing backups.

### Effects of Sewage Backups in a House

**1. Contaminated Water Supply:**
– Sewage backups can contaminate the home’s water supply, making it unsafe to drink or use for hygiene purposes.

**2. Structural Damage:**
– Water damage from backups can compromise the home’s structure, leading to weakened walls, floors, and foundations.

**3. Health Hazards:**
– Sewage contains bacteria, viruses, and parasites that pose serious health risks if they come into contact with people or pets.

**4. Odors and Pests:**
– Sewage backups emit foul odors that are not only unpleasant but can also attract pests, such as flies and rodents.

### Immediate Actions When a Sewer Backs Up

* Call a licensed sewage cleanup service immediately.
* Turn off the main water supply to prevent further damage.
* Open windows and doors for ventilation.
* Avoid contact with contaminated water.
* Document the damage with photographs or videos.
* Contact your insurance company to report the incident.
