If you’ve ever needed to pump or repair your septic system, you know how important it is to know exactly where your tank is. Unfortunately, many homeowners don’t have their septic tank location records handy, especially if the home is older or records were never properly filed. The good news is, there are several reliable ways to locate your septic system without tearing up your entire yard. In this guide, we’ll cover how to track down records, who to call, and what tools can help.
Quick Picks: Best Ways to Find Septic Tank Location Records
- Best Overall: County or Board of Health Records – Most counties keep septic system “as-built” plans on file.
- Best Budget: Probe & Visual Inspection – Using a metal probe or tracing sewer lines manually.
- Best Premium: Professional Camera & Locator Service (Roto Rooter, local septic companies) – High-tech locating with cameras and signal tracers.
Buyer’s Guide: How to Track Septic Tank Location Records
Before you start digging, here’s what you should know:
- Check County Records: Local health departments often have septic plans on file, sometimes including exact hatch locations.
- Follow Sewer Pipe: Inside your basement, see where the sewer pipe exits. The tank is usually 10–20 feet straight out from that point.
- Use Visual Clues: Look for greener grass, melted snow patches, or slight dips in the yard.
- Hire Pros: Companies like Roto Rooter use cameras, flushable transmitters, and electronic locators to pinpoint tanks.
- DIY Tools: A metal probe, rebar, or even a metal detector can help locate shallow tanks with concrete or metal lids.
- Confirm & Record: Once located, always measure from permanent landmarks (like house corners) to create your own record for future use.
