A perc test tests the rate at which water drains through the soil. A perc test is conducted by drilling or digging a hole (or multiple holes) in the ground, pouring water into the hole, and then observing the rate at which water percolates, or is absorbed in the soil.
Soil Perc Test Hole Width: a typical soil test pit is two feet wide. It may be larger depending on the excavator’s skill and on local soil conditions. Perc Test Shape: The bottom of the pit should be level and about 2 ft. x 4 ft. in size. This is important to permit accurate measurement of the soil pecolation rate.
The Perc Test A Perc Test (also known as “Perk Test”, and more formally known as a Percolation Test), is a soil evaluation that tests the rate at which water drains through the soil.
The time is recorded for the water to drop 1 inch, the water is replenished to the original depth. This test is performed until the 1 inch water drop times stabilize, usually 4-5 times. In the rest of this article I will describe how to do a soil percolation test also known as a perc test.

What is the purpose of a perc?
This combination medication is used to help relieve moderate to severe pain. It contains an opioid pain reliever (oxycodone) and a non-opioid pain reliever (acetaminophen).
How deep do PERC holes have to be?
A General Procedure for Conducting a Perk Test Dig the test holes – Most jurisdictions require the holes to be 4 to 6 inches in diameter and dug to a depth of 18 to 36 inches. You need at least two holes, but it’s better to have more.
How do you dig a PERC hole?
A percolation test, or perc test, is a procedure performed to review water drainage in different soils. It is important for many uses, such as when designing a leach field for a septic system, planning a building design, or considering agricultural use of the land.
How do you fix a failed perc test?
OPTIONS IF SITE FAILS Even if your site fails a perc or deep-hole test, all is not lost. For sites with high water tables, you may be able to “de-water” the leaching area by strategically placing gravel-filled trenches and subsurface drain pipe to conduct water away from the drain field.
What time of year is best to do perc test?
The time of year can definitely affect perc test results as well as the level of the water table, which is also a concern. In general, the driest season will yield the best results since dry soil readily absorbs water and the water table is lowest. Soil saturated with water from rain or melted snow will not perc well.
How long should it take for water to drain on a perc test?
A rate of 60 minutes per inch (MPI), meaning the water dropped one inch in 60 minutes, is often the cutoff point for a standard gravity-flow septic system, although the maximum number varies from 30 to 120 MPI depending on local regulations.
Does rain affect perc test?
Ideally, a percolation test will be performed when the ground is saturated, or just following a significant rain storm. If it has not recently rained, you may want to repeat step 3 before conducting the experiment.
How do I get a perk test in Michigan?
Perk tests can be do-it-yourself missions, but you will need some government assistance. Contact your local health department and arrange for an inspector to be on site during testing. The health inspector verifies if the perk holes are efficient and witnesses their drainage times during saturation.
How deep do you dig for a perc test?
