Sewer Line Repair in La Plata, MD

The Problem

A homeowner in La Plata, MD (20646) noticed a wet spot in their yard that persisted even during dry weather. The grass over the area was unusually green and lush compared to the surrounding lawn. There was a faint sewage odor near the wet spot.

The home was built in 1985. The homeowner had never had any sewer work done.

The Diagnosis

The wet spot, lush grass, and sewage odor are classic signs of a leaking sewer line. We performed a camera inspection from the cleanout access point.

The camera revealed a joint separation at the 32-foot mark — the pipe had shifted and the joint had opened, allowing sewage to leak into the surrounding soil. The pipe material was cast iron, original to the 1985 construction. The joint separation was likely caused by soil movement over the 40-year life of the pipe.

The rest of the line was in fair condition — some corrosion on the cast iron but no other joint separations or structural failures.

The Solution

We excavated to access the separated joint — approximately 4 feet of excavation to reach the pipe at 3.5 feet depth. We replaced the separated section with new PVC, properly bedded in gravel and backfilled.

We hydro jetted the entire line after the repair to remove any debris that had accumulated in the pipe belly near the separation point.

A post-repair camera inspection confirmed the repair was correct and the line was clear.

The Outcome

The wet spot in the yard dried up within two weeks of the repair. No sewage odor. The homeowner had the rest of the sewer line assessed — the camera inspection showed the remaining cast iron was in fair condition and could be monitored rather than replaced immediately.

Key Takeaways

• A wet spot in the yard with lush grass and sewage odor is a classic sign of a leaking sewer line
• Joint separation in cast iron pipe is common in Maryland homes built before 1990
• A camera inspection identifies the exact location and nature of the failure before excavation
• Spot repair is appropriate when the rest of the line is in acceptable condition
• Post-repair camera inspection confirms the repair was successful
