What is Percolation Testing?

Percolation testing, commonly known as a “perc test,” is a method used to assess how well soil can absorb and drain water. This test is especially crucial when determining if a site is suitable for septic system installation or, more importantly, when evaluating the potential impact of a development on local groundwater resources.

How Does Percolation Testing Work?

The process of percolation testing involves several steps. First, it requires digging a hole in the ground. Then, the hole is filled with water, and the rate at which the water drains away is measured. This measurement, known as the percolation rate, subsequently helps determine the soil’s capacity to handle wastewater disposal. Understanding this rate is vital, as it ensures the proper and safe installation of septic systems or other water-related infrastructure.

Why is Percolation Testing Important?

Percolation testing is an essential step in site assessment because it provides critical information that influences key decisions about site development. Furthermore, it affects septic system design, storm water management, and potential impacts on the local water table. By conducting a perc test, professionals can, therefore, ensure the safety, functionality, and sustainability of construction projects.

Percolation Testing Standards and Regulations

Percolation testing is a standardized procedure that is typically regulated by local or state authorities. While the specific requirements and procedures may vary by location, the fundamental principles of the test remain consistent. Consequently, it is important for anyone involved in planning, design, or construction to understand the basics of percolation testing to ensure their project meets local regulations.
