Signs You Need Your Septic Tank Located (Before You Start Digging)
If you can't point to your septic tank in your own yard, you're not alone. This is a super common issue. There are six situations where it’s time to call a septic tank professional to locate your tank instead of guessing: you're new to the property, your old markers are gone, you're planning to dig or landscape, a Transfer of Title inspection is coming up, your pumper can't find the lid, or you're troubleshooting a slow drain. A locate uses camera and radio transmitter technology to pinpoint your tank, distribution box, and leach field in about an hour, without tearing up your yard to find out.
First, let's clear up the AirTag question
People ask about this a lot: can you just drop an AirTag near the tank and find it that way?
No. AirTags run on Bluetooth, and Bluetooth signals don't travel through several feet of soil. Metal detectors run into the same wall if your tank is buried deep or made of concrete instead of steel. And that spot your neighbor's old markers, a paver, a garden statue, a mental note of "ten feet past the crabapple tree" doesn't hold up out here either. Southwest Colorado gets real freeze-thaw cycles every winter, and frost heave shifts soil enough that a marker placed five years ago can be sitting a few feet off by now. If you genuinely don't know where your tank is, the fastest and least destructive way to find out is a camera and radio transmitter, not a gadget built for tracking your keys.

The 6 signs it's time for a professional locate
1) You're new to the property and have no records
Southwest Colorado has a lot of properties that changed hands more than once, sometimes decades ago, and septic records don't always travel with the sale. If you just moved to Durango, Hesperus, Mancos, Bayfield, or anywhere in the Four Corners and nobody handed you a system diagram, that's normal. It's also the exact situation a locate is built for.
2) Your old markers disappeared
Even if the last owner (or the last pumping company) marked the lid, markers move or vanish. Landscaping changes, snow removal shifts gravel and soil, and a wooden stake rots in a season or two out here. If the marker's gone, so is your shortcut, and probing the yard yourself risks cracking a lid you can't see.
3) You're planning landscaping, construction, or excavation
Before you put in a fence post, a shed, a new driveway, or bring in equipment for a bigger project, you need to know exactly where the tank and leach field sit. Digging into a tank or crushing a leach field is a five-figure mistake, not a five-minute fix. This is one of the few times we'd tell you to call before you touch a shovel, not after.
4) A Transfer of Title or Continued Use Permit inspection is coming up
If you're buying or selling in La Plata or Archuleta County, the septic inspection isn't optional, and the inspector needs access to the tank. Locating it ahead of time keeps the inspection (and the closing timeline) from stalling out. We handle both locating and Transfer of Title inspections, and doing them together saves you a second trip.
5) Your pump-out company can't find the lid
This is the most common way people end up calling us. A pumping crew shows up, can't locate the access point, and now the appointment that was supposed to take twenty minutes is stalled. If it's time for a pump-out and nobody's sure exactly where the tank is, locating it first turns a frustrating truck visit into a routine one.
6) You're troubleshooting a slow drain or backup
A gurgling drain or a slow-draining tub sometimes points to a line problem, not just a full tank. When that's the case, we don't just locate the tank, we can run a line scope at the same time to check for blockages, root intrusion, or damage. Since the camera's already in the line, it's efficient to check both at once.
What locating typically costs
Durango Septic prices locating based on the complexity of the job, not a flat fee, since a system with a known access point is a much faster job than one with no records and multiple possible entry points. Manual labor during a locate, when it's needed, runs $140 per hour in 15-minute increments. For a general sense of what professional septic locating runs nationally, here's recent published data:
| Inspection Type | What's Included | National Average Cost |
|---|---|---|
| Basic locate | Checks for leaks, measures waste | $100 – $450 |
| Detailed inspection | Plumbing through leach field, soil test | $400 – $700 |
| Title V / transfer inspection | Required for selling or expanding a property | $500 – $900 |
| Camera / line scope | Camera run through main line or plumbing | $250 – $1,175 |

Why it's worth getting it right the first time
Guessing wrong costs more than calling first. A new septic system installation in Colorado runs $10,000 to $30,000 depending on the property, and that's the kind of bill you're risking if a shovel, an excavator, or a new fence post lands on a tank or leach field you couldn't see. A professional locate is a fraction of that risk, done once, done right, and it means every future pump-out, inspection, or repair starts from a known spot instead of a guess.
Why Durango Septic (to locate your tank)
With 20+ years of experience, Durango Septic uses camera and radio transmitter technology to locate your tank, distribution box, and leach field accurately, without unnecessary digging. We're also one of the few septic companies in the area running our own Bobcat mini excavator as part of our septic services, so if a locate turns into "we need to expose this lid" or "let's get a riser in while we're here," we don't need to bring in another company to do it. We answer the phone, we explain what we find, and we serve the whole Four Corners region: Durango, Bayfield, Cortez, Vallecito, Ignacio, and Pagosa Springs.
As one client put it: "Durango Septic is a pleasure to work with. They answer their phone, fit me into their schedule with short notice, was very communicative, and arrived on time. They also answered all my questions while they were performing the work." (Christopher, verified review)
If you're not sure where your septic tank is, request a locate and we'll find it without tearing up your yard to do it.
FAQ
Will locating my septic tank damage my yard?
No. Camera and radio transmitter locating is non-invasive. There's no test-digging or probing involved, since we're tracking a signal from the surface rather than physically searching for the tank.
How long does a professional locate take?
Most residential locates take about an hour, though it depends on how accessible your cleanout is and how far the tank sits from the house.
Do I need to locate my tank every time it's pumped?
No, not if the access point is already marked or has a riser installed. A riser brings the lid up to ground level permanently, which is why we often recommend adding one once we've located a buried tank, so you don't have to pay to relocate it again.
What if I've never had my septic system serviced at all?
That's more common than you'd think, especially with older Southwest Colorado properties. A locate is the right first step. Once we know where everything is, we can tell you the condition of the system and what kind of maintenance schedule makes sense going forward.
Can I try to locate my septic tank myself first?
You can start with your property records or your county health department, which sometimes has a system diagram on file, and check where your sewer line exits the house as a rough starting point. But without equipment, you're guessing at depth and exact position, and a wrong guess means unnecessary digging. If you want a confirmed location before you commit to any yard work, a professional locate is the faster and safer route.
