You will have to present your plans to the proper local governMentdepartment to get your permit.

2. The location you choose to install the drain will require a percolation test. A percolation test measures the ability of water to soak into the ground. This test will tell you how porous the soil is and the length of the field lines that will need to be installed. The size of The tank you acquire will depend on the number of bedrooms in the home. The results of the percolation test will allow the inspector to determine the type of materials you need for it such as sand, gravel, fill dirt, and topsoil.

3. You will have to measure for the installation of the lines. Some people will use a surveyor to measure and record the dimensions.

4. Once you have the correct measurements, dig the trenches for the field lines. The depth of the fieldlines will be determined by the depth of the outlets from the septic tank. When digging field lines, make sure there is a slight slope so that there will be proper drainage.

5. Lay the drain pipes in the field line trenches and attach them to the outlets from the septic tank. Once this is done, fill the septic tank with water.

6. Fill in the field lines with the percolation test determined materials such as gravel, sand, dirt ... etc. Once you have it filled in properly, you will likely have to get another final inspection. After you pass the inspection, you can lay sod or grass plant. Remember, when you are covering the drain fields, there should be a slight mound to prevent water from draining on the property.
