Percolation Test
A percolation test, commonly called a "perc test," is a soil assessment that measures how quickly water drains through the ground at a specific location. This test is essential for determining whether a property can support a septic system by evaluating the soil's ability to absorb and filter wastewater.
Example
“The county required a percolation test before approving the septic system installation for the new home.”
Memory Tip
Think 'perk up' your coffee - just like coffee perks through a filter, water perks through soil in a perc test.
Why It Matters
Properties without access to municipal sewer systems require a functioning septic system, and failing a perc test can make a property unbuildable or significantly reduce its value.
Common Misconception
Many people think a perc test only needs to be done once, but soil conditions can change over time and may require retesting for new construction or septic system replacements.
In Practice
A buyer interested in building a home on rural land discovers during due diligence that the property failed its perc test, meaning they cannot install a septic system and must either connect to distant municipal sewer lines at great expense or abandon the purchase.
Etymology
The term comes from the Latin 'percolare' meaning 'to strain through,' reflecting how water filters through soil layers during the test.
