Your septic designer hard at work
Performing a perk test (these days it’s known as a preliminary soil analysis) means getting down into the soil to see what’s going on. Since we don’t actually pour water in the holes and watch the perk rate anymore, getting down in the holes and inspecting the soil strata is necessary to see the soil looks like. Soil color is a big indicator of water levels, and we’re always trying to stay above the winter water table level.
