Installing a Septic Drainfield in 7 Simple Steps

Before installing a septic drainfield you need a functioning septic system that will process human waste and then send it to the drainfield. The waste is first sent to a septic tank for storage and initial processing. Grey water is discharged from the septic tank and sent to the drainfield via outlet pipes. The septic drainfield then continues the recycling and purification process. Installing a septic drainfield is not an easy task and requires ample know-how and the right tools to get the job done.

A septic system and a septic drainfield are usually both installed at the same time. Here are 6 things you need to consider before you go ahead and have your septic system installed:

  • Step 1 – Pick the Location:Depending on the location, the installation process varies. To be on the right side of the law, make sure you have all the legal permits and documentation before you start. You should have inspectors from the local health authority inspect the septic drainfield installation site and give their recommendation about proceeding. Once the authorities from the local government approve the plan you presented, then a permit is issued to allow you to commence installing the septic drainfield.
  • Step 2 – Measure the Percolation Rate:The most important consideration when installing a septic drain field is the percolation rate of the soil. The percolation ability has to be tested by measuring how fast water on the ground is absorbed into the soil. Using this test, you will be able to find out if the soil is porous and determine whether it is a suitable area for installing a septic drainfield.
  • Step 3 – Pick A Septic Tank Design:Research various septic tank designs and choose the one that is best suited to your needs. You can receive expert advice from a qualified septic contractor, often for free or just a small fee.
  • Step 4 – Make Accurate Measurements:Use the right measurements for installation is key. If you are not good at measuring accurately then hire a surveyor to help you get the right dimensions.
  • Step 5 – Start Digging the Trenches:With all correct measurements in place, it is time to start the ground work beginning with digging the trenches that will hold the field lines. What dictates the depth of the trench is the depth of the discharging outlet of the septic drainfield tank. The field lines should be put on a slight downward gradient away from the storage tank to enhance a proper drainage system.
  • Step 6 – Prepare the Dug Out Trenches: For better performance and reduced clogging, enhance percolation by filling in the trench lines with materials like sand or gravel. There are types of gravel made specifically for septic drainfields.
  • Step 7 – Lay the Drainage Pipe:Once the trenches are dug it is time to lay down all the drainage pipes.

Now that you have accomplished the general installation process, you can ask the authorities to come for the final check and give their final approval. With approval, you can embark on the task of landscaping the area around the septic tank and septic drain field. Here’s a free tip for you, install septic risers for easy access to the tank and septic tank covers for aesthetics.

It is a matter of necessity that modern homes today are built with the right septic system. If you can do the installation of the septic drainfield by yourself then do it, you will save a lot of money. You can always consult a professional along the way to help you with anything you cannot handle.
