Septic Perc Test Procedure, Test Pit: Fast Draining Soils

Fast percolation soils and Septic Systems, often these soil types don’t treat wastewater very efficiently. This video showcases a site investigation where fast percolation soils are dominant.

Wow that looks like an old gravel bar from a lake or river/creek that once ran through there.

In your opinion, what is the best way to determine where to put a test pit to hopefully not run into a fast percolation soil? Secondly, how does someone avoid the exact opposite where there is an abundance of clay and non-well drainage? What physical characteristics above ground should home owners look for identifying best locations for test pits and Septic Systems?

We normally conduct test pits in close proximity to the area we deem the septic field should be located in. Regardless of the soil types. We conduct 2 or more test pits to determine consistency in the soils for that location. We then design the septic system for the soil types that we encountered during testing. We look for drain field locations where it is out of the way of vehicle travel, we look for locations that are fairly accessible for maintenance providers, and we look for relatively flat zones without too much slope.
