Sewage Backing Up Into Your Basement? Act Fast

Sewage Backup Is a Health Emergency

When raw sewage backs up into your basement, you are dealing with Category 3 water damage -- the most hazardous classification. This water contains bacteria, viruses, parasites, and other pathogens that can cause serious illness. E. coli, Hepatitis A, and Giardia are just a few of the organisms present in untreated sewage. The moment you notice sewage in your basement, treat it as an emergency.

Homes in Lancaster and Lebanon counties are particularly susceptible to sewer backups for several interconnected reasons: aging clay tile sewer lines, expansive clay and shale soil that shifts with moisture changes, mature trees with aggressive root systems, and in some older neighborhoods, combined sewer systems that handle both sanitary waste and stormwater.

Common Causes of Sewer Backups in Lancaster County

Tree Root Intrusion

Tree roots are the number one cause of sewer line blockages in our area. Silver maples, willows, and other water-seeking species send fine feeder roots into the smallest cracks in clay tile and Orangeburg pipe -- a tar-paper material used extensively in homes built between the 1940s and 1970s. Once inside, roots expand and trap grease, paper, and debris until the line is fully blocked.

Aging Pipe Materials

Many homes in Lancaster, Lebanon, and the surrounding communities still have original clay tile sewer lines. Clay tile was durable for its era, but the joints between sections were sealed with mortar that deteriorates over decades. Each failed joint becomes an entry point for roots and groundwater. Orangeburg pipe, which was made from compressed wood fiber and tar, has a typical lifespan of 30 to 50 years and collapses under the weight of soil over time.

Clay and Shale Soil Movement

Lancaster County sits on clay and shale bedrock with heavy clay topsoil. This soil expands when wet and contracts when dry, creating a cycle of movement that can shift, crack, and separate sewer pipe joints. The freeze-thaw cycles of winter compound the problem by lifting and settling the soil around buried pipes.

Grease and Debris Buildup

Cooking grease, so-called flushable wipes, and other debris accumulate inside sewer lines over time. Even pipes in good structural condition can develop blockages from years of grease coating the interior walls and reducing the effective diameter.

Immediate Steps When Sewage Backs Up

Stop Using Water

As soon as you notice sewage in your basement, stop all water use in the house. Do not flush toilets, run sinks, or use the washing machine. Any water you send down the drain has nowhere to go and will add to the backup.

Ventilate the Area

Open basement windows and doors if possible to ventilate the space. Sewer gas contains methane and hydrogen sulfide, both of which are hazardous in enclosed spaces. Do not enter the flooded area without rubber boots and gloves, and avoid prolonged exposure.

Turn Off Electrical Power

If standing water is near electrical outlets, appliances, or your breaker panel, shut off the breaker for the basement from the main panel before entering the area. If you cannot reach the panel safely, call your electric utility for guidance.

Do Not Attempt DIY Cleanup of Raw Sewage

Sewage cleanup requires specialized equipment, disinfectants, and protective gear. Professional restoration companies use industrial extractors, antimicrobial treatments, and commercial dehumidifiers to properly decontaminate affected areas. Drywall, carpet, and insulation that have absorbed sewage almost always need to be removed and replaced.

Professional Sewer Line Diagnosis

When our team arrives for a sewer backup, the first step is a video camera inspection of your sewer line. A waterproof camera on a flexible cable is fed through the line from a cleanout access point, allowing us to see the exact location and nature of the blockage -- whether it is roots, a collapsed pipe, grease buildup, or a foreign object.

This inspection is critical because the treatment depends entirely on the cause. Root intrusion may be resolved with mechanical cutting and preventive root treatment. A collapsed pipe section requires excavation or trenchless repair. A grease blockage responds to hydro-jetting. Without a camera inspection, you are guessing at the solution.

Preventing Future Backups

After the immediate problem is resolved, consider these preventive measures:

- **Install a backwater valve** on your main sewer line. This device allows sewage to flow out but prevents it from flowing back into your home during municipal sewer overloads or heavy storms. - **Schedule regular sewer line inspections** every two to three years, or annually if you have mature trees near the line. - **Dispose of grease properly** by collecting it in a container and discarding it with solid waste rather than pouring it down the drain. - **Avoid flushing wipes, feminine products, and other non-degradable items** that accumulate in sewer lines.
