In the world of septic systems, it’s common to hear the term “Percolation Test” thrown around and most people have no clue what this test even is or how it pertains to wastewater systems in general. In today’s blog post, we want to explain the basics of percolation testing to help you determine if you need might ever need one.
Septic systems allow homeowners and businesses to build on remote properties and vacant land no matter how far they are from the existing sewer connections. However, determining if a septic tank will actually work for their property requires more than just the new owner’s readiness to pay for the installation of the system. This is where percolation testing comes into play.
A percolation test, also known as a “perc test”, is typically required before your county can approve a permit for the installation of your new wastewater system.
What does a percolation test show?
A percolation test shows how well the soil in particular parts of a property drains. Septic systems work off of drainage rates which determine how fast waste escapes before it gets a chance to break down. In some cases, if it’s draining too slow, the tank can fill up and overflow.
How is a percolation test done?
Percolation tests vary slightly but they all have the same basic factors involved. Each test involves digging a hole of a certain depth, filling the hole with water, then measuring how long it takes for the water to fully drain into the soil. Holes are typically dug anywhere from 4.5 to 10 feet deep.
When do you need percolation testing done?
Percolation tests are usually done before you install a new septic system. They’re occasionally also done if there’s a problem with an existing drain field on a property to determine if soil qualities are causing problems. Relocating a septic system also requires testing since there could be different soil drainage levels in the new location.
