The âPerc Testâ. A Perc Test (also known as âPerk Testâ, and more formally known as a Percolation Test), is a soil evaluation that tests the rate at which water drains through soil.
Many greywater codes use a soil type chart to predict drainage rates instead of percolation rate data. Greywater percolation tests should be conducted at the depth of discharge, ideally less than one foot. How to do a home soil percolation test: Step 1. Dig a 6â³-12â³ deep hole in your future greywater infiltration zone. Step 2. Place a ruler (or stick marked in inches) in the bottom of the hole. The measuring device should reach the top of the hole. Step 3. Fill the hole with water several times to saturate the soil.
