Septic Testing (Test Pits & Percolation)

Accurate Soil Testing in Greater Philadelphia: The Foundation for Your Septic System

Before designing or installing a septic system, understanding your soil’s characteristics is crucial. Gray Brothers provides expert test pit excavation and percolation (perc) testing services throughout the Greater Philadelphia area. Our accurate testing provides the essential data needed for compliant, effective septic system design, protecting your investment and the environment.

Understanding Septic Soil Testing

What is Percolation (Perc) Testing? A perc test measures the rate at which water drains through soil. This absorption rate is critical for determining if the soil can support a drain field and how large that field needs to be.
What are Test Pits? Excavated pits allow for visual inspection of soil layers (horizons), identifying soil type, texture, and checking for seasonal high water tables or restrictive layers (like rock) that could impact system design.
Why is Testing Necessary? Local health codes require soil testing before a septic system can be designed or permitted. It ensures the system is appropriately sized and designed for the site’s specific conditions, preventing failure and protecting groundwater.
The Testing Process: Learn how holes are dug, presoaked (if necessary), and timed measurements are taken to calculate the percolation rate (minutes per inch).
