Excavating questions, answered by experts

Generally, a trenchless sewer line is worth the cost. If your old system needs replacement, trenchless sewer repair or replacement can save you thousands on excavation costs. Every homeowner’s situation is different, but this method is definitely worth it in a lot of cases.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

Trenching is a specific kind of digging. Trenching means digging a depression in the earth that’s deeper than it is wide, often with heavy machinery. Digging refers to any kind of removal of earth in order to create a human-made depression, hole, or cut in the earth’s surface. You can dig with big tools or even with just a hand shovel.

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.
