Before any sewer work begins, it’s crucial to know exactly where your pipes are buried. Accurate locating helps you avoid costly damage and keeps your project on track.

Using advanced equipment, we can locate sewer lines under driveways, landscaping, and even concrete slabs in neighborhoods from Brightwater to Huntington Central Park.
Whether you’re planning a remodel, adding a pool, or handling a sewer emergency, knowing where your lines run is the first step to a safe, successful project.
When You Need Sewer Line Locating Services
Advanced Technology Makes All the Difference
Modern sewer line locating is no longer guesswork. Today’s high-tech tools let us pinpoint underground sewer lines with exceptional accuracy. We use electromagnetic locators to trace metallic pipes and ground-penetrating radar (GPR) to detect non-metallic lines like PVC or clay.
Our advanced electronic equipment sends a signal through your sewer line that we track from above ground. This method works even when pipes are buried deep or run under concrete driveways and patios, and it also shows us the pipe’s depth.
For more complex properties, we use GPR to create detailed images of everything underground, including sewer lines, old foundations, utilities, and large tree roots.
We also combine video inspection with our locating tools. The camera shows the condition inside the pipe, while our locator tracks its exact path—giving you a complete and accurate view of your sewer system.
The Mystery Under Magnolia Street
About five years ago, we got a call from a homeowner near Magnolia Elementary who was planning to build a backyard deck. He’d received three different opinions from contractors about where his sewer line was—and all three were completely different.
Before letting anyone dig, he called us. Using our electronic locating equipment, we found that his sewer line actually curved in an S-shape to avoid a tree that had been removed years earlier. The original builders had routed the pipe around it, creating a path no one expected.
If the contractors had relied on guesses, they would have missed the sewer line entirely and likely damaged his sprinkler system. We marked the exact route, and he was able to build his deck safely with no surprises.

Avoid Costly Damage: Always Locate Your Sewer Lines First
Common Sewer Line Locating Mistakes That Cause Problems
- Assuming sewer lines run straight: Many older homes have sewer lines that curve around obstacles, follow property boundaries, or even connect through shared easements. Without proper locating, you can end up digging in the wrong place.
- Relying on basic metal detectors: Metal detectors may find cast iron or steel pipes, but they can’t locate PVC, clay, or concrete lines. They also can’t show pipe depth or direction, making them unreliable for accurate sewer line locating.
Common Locating Mistakes That Cause Problems
The biggest mistake is assuming your sewer lines run straight from your house to the street. Many older homes have sewer lines that curve around obstacles, follow property lines, or connect to neighbors’ lines in shared easements. Without proper locating, you might dig in the wrong spot entirely.
Another problem we see is people trying to use basic metal detectors to find sewer pipes. Metal detectors can find cast iron or steel pipes, but they won’t locate PVC, clay, or concrete pipes. Plus, they can’t tell you how deep the pipes are buried or which direction they’re heading.

Yes, our equipment works through concrete, asphalt, and other hard surfaces. The signals penetrate these materials easily, so we can map lines under driveways, patios, and sidewalks without any problem.
We use spray paint for temporary marking that lasts several weeks. For permanent marking, we can install small flags or stakes, though most homeowners prefer temporary marking since it eventually fades away naturally.
Our equipment can locate lines up to 15 feet deep in most soil conditions. Huntington Beach’s sandy soil actually makes deep locating easier because the signals penetrate well without much interference.
Most residential properties take 30 minutes to 1 hour for complete line locating. Larger properties or complex layouts might take longer, but we’ll give you an accurate time estimate when we arrive.
Not at all. Our equipment works entirely from the surface without any digging or invasive procedures. We’re careful around planted areas and always clean up any spray paint overspray.
