The drain field is one of the most important parts of a septic system, but many people don’t know much about them or how to maintain them. Here’s a guide to your septic tank’s drain field.

Commonly Asked Questions About Drain Fields

What is a drain field?

A drain field, or leach field, is a system of underground pipes that slopes downwards and eliminates waste and impurities that are in the water released by your septic system. The pipes within the field have drilled-in holes that allow the water to filter into the field, which contains a porous material, such as gravel, so that the water is filtered thoroughly.

How large is the typical drain field?

The size of a leach field usually varies based on the size of the septic tank and the soil type in the area. Most of the pipes are about three feet wide, with beds of clean dirt that are six feet between them. In some cases, the trenches could be as long as 100 feet long. The pipes will be buried at least six feet underground, but it could be as deep as five feet if the soil quality requires it.

Why do I have issues with my septic system when it rains?

If you have issues with your septic tank when it rains, this is probably a problem with your drain field. When there’s heavy rain, your drain field will become saturated, meaning that the water can’t flow out of your septic tank. Since the water can’t go anywhere, it may flow back up through the drains in your house, so if you have this problem, try not to use your system too much until the rain dries out. Next time it rains, consider finding a way to divert water away from your drain field or contact a professional to pump or inspect your septic system.

How do I care for my drain field?

You don’t have to do much to maintain your leach field. Don’t drive a heavy vehicle over the drain field, as this can cause damage by compressing and cracking the pipes, or dislodging the gravel. Also, avoid building a shed, swing set, or other foundational structures over the drain field, as this limits its ability to filter water. Lastly, don’t waste or use excessive amounts of water, as this can cause your drain field to become saturated.
