## Step 1: Check Your County Health Department 'As-Built' Map

Before picking up a shovel or probe, check your local municipal records. In nearly all jurisdictions across the US, UK, Canada, and Australia, onsite sewage permits require an **'as-built' drawing** filed with the county environmental health department.

This document contains precise measurements from fixed landmarks (e.g. *"18 feet north of back patio corner, 12 feet east of oak tree"*) showing the exact coordinates of the primary septic tank and absorption trenches.

## Step 2: Trace Your Main Plumbing Exit Line

If no drawing exists:

- Go to your basement, crawl space, or utility room and find the main **4-inch cast iron or PVC sewer stack**.
- Note the exact point and direction where the pipe penetrates the foundation wall towards the exterior yard.
- Walk directly outside along that straight line. Residential septic tanks are typically installed **10 to 25 feet away from the foundation**.

## Step 3: Use an Insulated Soil Probe

- Use a 48-inch steel T-handle soil probe.
- Push the rod gently into the turf every 12 to 18 inches along the path of the sewer exit pipe.
- In standard soil, the probe slides easily through topsoil until it strikes solid resistance (concrete or fiberglass) at a depth of **12 to 36 inches**.
- Once you hit solid resistance, probe in a cross-pattern to outline the rectangular perimeter of the tank (typically 5 ft wide by 8 ft long).

### Frequently Asked Questions

#### How deep are septic tank lids usually buried?

Most septic tank lids are buried between 6 inches and 36 inches below ground level. In colder northern climates, tanks are buried deeper (3 to 4 feet) to stay below the frost line.

#### What is the best way to avoid digging for lids in the future?

Install plastic or HDPE risers and screw-down green lids that bring the access opening flush with the grass surface. Risers cost $300–$500 once and pay for themselves by eliminating digging fees on every future pump-out.
