A field drain or septic system drainfield is an area which is excavated, and is used to remove contaminants and other impurities from the septic tank. A field of Septic consists of several trenches that are filled with a perforated pipe and gravel so that the liquid can flow through the gravel and soil.

Percolation Test: Before you can dig your septic tank drain, you'll need the soil tested to ensure it is appropriate to the specialization. The test is called a percolation test and it ensures that the soil is permeable enough for septic runoff and soak in filter bacteria.

Installation: To build a septic field, dig several 10-25 foot long trenches. The ditches need about 3 feet deep and 3 feet wide. Then the line of gravel trenches and install your pipe. After the pipe is, fill the trench with the rest of the way over gravel. Then, add a damp garden with small holes on the gravel. Once done, fill the trench with earth. Wait a week or two and add more dirt that settled the area a bit.
