  • Due to the various approval agency requirements and depending on your county, percolation testing and permeability of soils testing for septic is best done in the late summer or fall. While you can do a percolation test at any time of year, summer/fall yield the driest ground conditions that provide the best percolation test rating. The worse the rating, the larger the system you may need to install because the size of the system depends on how good the ground allows water to permeate. The difference between ratings can double the size required for a system that already takes up a lot of room. Don’t let septic be an issue for your project.
