# Buried Drain Locating and Troubleshooting in Denver

Drain locating uses a sonde transmitter run through the pipe on a camera head to trace the exact path and depth of a buried drain line from the surface. Denver Sewer and Water uses locating to solve problems a camera alone cannot, including undocumented lines, mystery connections, and drains that cross property lines without a record.

- Sonde locating to trace buried drain lines from the surface.
- Depth marking before any excavation is planned.
- Undocumented line routes identified and recorded.
- Troubleshooting for symptoms with no obvious cause.
- Residential and commercial buried drain systems.

## When Do You Need a Buried Drain Located Rather Than Just Cameraed?

A camera survey tells you what condition the inside of the pipe is in. It does not by itself tell you where that pipe sits relative to the surface, unless a sonde is run alongside it and traced. On a property where nobody knows the drain's route, whether because records were never kept or because a previous owner did unpermitted work, locating is the step that turns a camera finding into an actionable plan.

We also use locating to troubleshoot symptoms that do not have an obvious cause: a wet spot in the yard with no visible fixture problem, a drain that backs up only when a specific area drain is used, or a suspected connection between two systems that should not be tied together.

- Excavation or trenchless repair is being planned and the exact route is unknown.
- A wet spot or settling ground suggests a leak with no visible source.
- A property has no as-built drawings for its buried drainage.
- A drain crosses a property line or runs under a structure built after the line was installed.
- A suspected illicit connection between drain, sewer, or storm systems needs confirming.

## How the Sonde Locate Works

The transmitter rides in the camera head as it moves through the pipe, and a handheld receiver on the surface picks up its signal, letting us walk the exact route above ground and mark it. At any point we can also read depth, which is what lets a repair crew dig in the right place instead of test-pitting along the suspected path.

Where the line runs under concrete, asphalt, or landscaping that cannot be disturbed for a test pit, this is the only practical way to confirm a route before committing to excavation.

- A marked surface route of the buried line.
- Depth readings at intervals along the run.
- Confirmation or correction of any assumed path.
- A record the property owner keeps going forward.

## How a Locating Call Runs

1. **Camera the run with the sonde active** The transmitter travels with the camera head so location data is captured alongside condition.
2. **Trace the signal from the surface** A handheld receiver follows the transmitter, letting us walk and flag the route above ground.
3. **Mark depth at intervals** Depth readings are taken and recorded along the traced path, not just at the endpoints.
4. **Document the findings** The marked route and depth data are handed over so future work does not start from scratch.

## What Drives Locating Cost

Line length and how much of the route is obstructed by paving, structures, or landscaping are the main factors. A straightforward yard run is quick to trace. A line running under a slab or through multiple property boundaries takes longer to walk and mark accurately.

Locating is usually paired with a camera survey rather than billed as a completely separate visit, since the equipment does both jobs at once.

## Frequently asked questions

**Can you locate a drain line with no records at all?**

Yes. As long as the line will pass a camera and sonde, we can trace and mark its route regardless of whether any documentation exists for the property.

**How accurate is the depth reading?**

The receiver reads depth directly above the transmitter as it moves through the pipe, which is accurate enough to plan excavation without test pits in the vast majority of cases.

**Do you also locate interior branch lines behind walls?**

That work falls to our sister company Afford-A-Rooter Plumbing. We locate the buried drain and lateral outside the building envelope.

**Why would a drain line cross a property line?**

Older subdivisions and shared driveways sometimes have drainage that was routed across a boundary before current setback and easement rules existed. Locating confirms whether that is actually happening on your property.

**Can locating find an illicit connection between systems?**

Tracing the route combined with camera findings can confirm whether a drain, sewer, or storm line has been improperly tied into another system, which we then document for you.

**Do you work for the city or Denver Water when you locate lines?**

No. Denver Sewer and Water is a private, family owned and operated company. We are not Denver Water or the City and County of Denver. We work on the privately owned buried drain line on your property, from the building drain out to the connection point.
