We don't guess. We use the industry-standard Ridgid NaviTrack Scout — the same multidirectional locator used by municipal utility crews and licensed inspectors nationwide.
1. Guess where the tank might be
2. Dig 3-4 trenches across the yard
3. Destroy landscaping and irrigation
4. Still might not find it
1. Flush transmitter into sewer line
2. Track signal with NaviTrack Scout
3. Mark exact lid location on surface
4. Dig one small, precise hole
We flush a small, waterproof 512Hz electronic transmitter down your toilet or cleanout. It travels through the pipes into your septic tank and sends a signal upward through the soil.
Using the Ridgid NaviTrack Scout, we walk your yard tracking the 512Hz signal from above ground. The locator shows real-time depth, signal strength, and direction — pinpointing the tank within inches.
We spray-mark the exact lid location on your lawn. Then we dig one small, precise hole — usually 12 inches wide. No trenching. No backhoe. No guessing. Done in under 30 minutes.
If you've lost track of your septic tank lid — or never knew where it was — you're not alone. Thousands of Spokane-area homes have buried septic tanks with no visible markers, especially properties built before the 1990s. Rather than tearing up your yard, Spokane Septic Services uses digital 512Hz sonde locating to find your tank in minutes without destruction.
Our process pairs with our sewer camera inspection system. When needed, we feed a camera with a built-in sonde transmitter through your sewer line, then track the signal from above ground using the NaviTrack Scout. This dual approach gives us the tank location plus a full video assessment of your pipe condition.
For the most accurate locate, we pair our sewer camera with the NaviTrack Scout. The camera's built-in 512Hz sonde broadcasts a signal as it travels through your pipe.
This gives us two things at once: the exact tank location and a full HD video inspection of your sewer line. We can spot root intrusion, cracks, bellied pipe, and buildup — all before we dig.

Spokane County has some of the oldest rural septic infrastructure in Washington State. Properties in Mead, Nine Mile Falls, Deer Park, and Otis Orchards commonly have tanks installed in the 1960s-1980s with no recorded as-built drawings. Over time, previous homeowners paved driveways, planted trees, and built additions over the tank.
Without a digital locating service, you're left probing the yard with a metal rod or paying an excavation crew to trench at $100+ per hour. Our method costs a fraction and takes under 30 minutes with zero yard damage.
Real estate transactions require a septic inspection. If the seller doesn't know where the tank is, a digital locate saves days and prevents closing delays.
Previous owners covered it. The lawn grew over it. You paved over it. We find it — through soil, gravel, or concrete — in under 30 minutes.
Due for a septic tank pumping but can't find the lid? We locate first, then pump — same visit. No need to schedule two trips.
Want a septic riser installed so you never lose the lid again? We locate the tank, dig to the lid, and install a permanent access riser in one visit.
We provide digital septic tank locating across the entire Spokane metro area including Spokane Valley, Liberty Lake, Deer Park, Mead and Colbert, Cheney and Medical Lake, Otis Orchards, and Nine Mile Falls. We also serve rural Stevens County including Colville, Chewelah, and Loon Lake. Same-day locating available.
