Three Things to Know About Your Drain Field

Posted on: 29 October 2018


If you have a septic tank on your property, then you also have a drain or drainage field on your property as well. A drainage field is an important part of your septic system, and as a septic tank owner, you need to understand how your drainage field works and what you can do to take care of it.

What the Drain Field Does

The drain field is the final step in the septic system process. Coming out of your septic tank, away from your home, is a series of pipes. Coming out of these series of pipes is grey water. Grey water is the water that has been filtered through your septic tank but is not entirely clean water yet.

These pipes are located in the ground. This ground has been specifically filled with sand, gravel, and soil for the purpose of filtering out any remaining containments from the grey water before it hits the groundwater.

The drain field helps return the waste water that comes from your home back to the overall groundwater supply and the filtering process turns this water into safe drinking water.

How to Take Care of the Drain Field

Luckily, taking care of the drain field is relatively easy. It is more about how you use the space above the drain field than it is anything active you have to do with the drainage field itself.

You don't want to compromise the carefully laid layers of soil that make up your drainage field. The soil is specifically designed to ensure that once the grey water filters through all the layers in place, the water that remains is safe.

You don't want to put a lot of pressure on your drain field. For example, you should not build a driveway on top of your drain field. You need the free flow of moisture and air around your drain field, so you shouldn't cover it up with cement either. The less pressure you put on the drain field, the less likely the soil is to compact, and the less likely the intricate system of pipes will get cracked or damaged.

This should be an open area where perhaps you plant grass or flowers. Try to turn it into a space with minimum traffic.

Also, be careful about what you run off near your drainage field. It is already handing a lot of water behind the scenes and doesn't need to handle any more water.

Your drain field is the last crucial part of your septic system. It helps change the grey water that is filtered out of your septic system into drinkable water that can go back into the groundwater system.
