Does My Septic System Need a Drain Field Inspection?

Posted by ADB Septic on June 11, 2019

inspectionYour drain field is one of the most important parts of your septic system, but it is often overlooked. The drain field is responsible for taking wastewater from your plumbing, filtering it, and releasing it back into the ground as clean groundwater. Without a properly functioning drain field, your yard can flood, the environment around your home can be damaged, and you can experience health concerns related to contaminated water. Because your drain field is so important, inspections are necessary to ensure it’s operating optimally at all times. Are you wondering whether you need a drain field inspection? Check out the post below to help you decide.

Common Causes of Drain Field Issues


Unfortunately, one of the main causes of drain field failure is its age. A drain field has an average lifespan of 25 years, so if your drain field is around that age, it might be on its last legs. When drain fields reach this point, they need repair or a new drain field needs to be created.


When extra water ends up in your septic system, it can overwork your drain field. Dripping faucets, running toilets, or malfunctioning water softeners can all cause oversaturation. If usage is higher than normal for an extended period of time, in cases such as extended houseguests or overwatering plants during a drought, your system could get overloaded. When your system gets overworked, your drain field can flood.

Crushing Damage

When the soil in your drain field gets compacted, it will not drain properly. Vehicles, horses, and heavy permanent structures can compact the soil on your drain field. When this compacting occurs, your drain field will become damaged and will not function properly. Avoid placing heavy items on your drain field that will compact the soil.

Failure to Pump

When too much sludge builds up in your system, it will get backed up. This buildup will cause an excess of water to rush into your drain field and flood it. If left too long, raw sewage will also build up in your drain field. This sludge buildup can be easily avoided if you pump your system regularly. Failure to pump your system frequently can damage your drain field.

Soil Clogging at the Biomat Layer

The biomat layer of your drain field is a layer of bacteria that forms below and around the drain field trenches. This layer helps process the biological solids and pathogens in the sewage. Excess water or sewage can cause this layer to clog. If the biomat layer is not functioning properly, it cannot treat the sewage and nearby water sources could get contaminated.

Covered Drain Field

It’s important that your drain field is not sealed. Patios, pavement, decks, and other groundcovers should not be installed over your drain field. If your drain field is covered it will not drain and treat water properly and will malfunction.

Excessive Rainfall

In areas with an excessive amount of rain, your drain field can flood. In these areas, it’s important to use gutters to divert the water away from your drain field. If you fail to divert the rainwater, your drain field can malfunction and flood.

Signs of Drain Field Problems

There are a few different ways that you’ll know that your drain field is having problems and might be in need of repair. You might see pools of water in your yard, particularly over your drain field. When your drain field cannot properly treat the water it receives, it will lead to flooding because it cannot release the water gradually into the ground. The result of this flooding is the puddles you’ll see in your yard. You might also experience water backups or gurgling noises in the pipes in your home. When your drain field is not functioning properly, wastewater can actually travel back up your pipes into your home and cause these issues. Finally, the failure to filter wastewater can lead to bad odors coming from your drain field that could even seep into your home. If your yard or your home smells like sewage, drain field problems might be to blame.

Benefits of Drain Field Inspection

A drain field inspection can help you identify any problems with your drain field early on to avoid major issues. If you’re having problems with your drain field or your septic system, a drain field inspection is a good idea to assess the problem. Your septic services company will be able to determine a course of action, advising repairs or, in some cases, a replacement of your drain field. Having regular inspections, even when you’re not experiencing any problems, will help identify any issues early on in order to fix them before they can cause problems in your home or on your property. To ensure your drain field continues to function optimally, consider regular drain field inspections.
