Test pits can be excavated using two different methods, Hand excavation and or using an excavator.
Test pits are excavated along exterior walls, neighboring properties and columns to determine the depth of footings and or conditions.

A percolation test is a test to determine the water absorption rate of soil.
​
How Percolation Tests are performed
​
A percolation test consists of digging one or more holes in the soil of the proposed leach field to a specified depth, presoaking the holes by maintaining a high water level in the holes, then running the test by filling the holes to a specific level and timing the drop of the water level as the water percolates into the surrounding soil.​
