Top 5 Reasons Your Drain Field is Failing

Posted by ADB Septic on December 4, 2018

Your drain field is responsible for holding the wastewater from your septic tank and filtering it so it can be released back into the ground as clean groundwater. For this reason, it’s crucial to keep your drain field functioning properly to avoid damage to your septic system and contaminated groundwater. If you’re concerned that your drain field might be failing, you might notice signs like pooling water and bad odors coming from your yard. We’ve compiled a list of the top reasons that drain fields fail to help you avoid the issue from happening to you.

1. Oversaturation

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. Excessive rainfall can also lead to an oversaturated drain field, especially if you fail to use gutters to divert the water away from your drain field. When your drain field becomes oversaturated, it will become overworked, which will lead to serious damage. If this damage is continuous, it can cause your drain field to fail.

2. 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 the soil in your drain field compacts, wastewater cannot easily pass through it. This will lead to improperly treated wastewater and even a flooded drain field. To avoid this serious damage caused by soil compaction, avoid placing heavy items, or really any items, on your drain field.

3. Failure to Pump

Pumping your septic tank is important to empty the sludge and solid waste from your septic tank. When you fail to pump your tank, this solid waste will build up, pushing more and more water into the drain field at a quicker rate. When water pours into your drain field this quickly, your drain field will become overworked and can become damaged and even fail. Additionally, if the backup gets too severe, sludge and solid waste can seep into your drain field. This waste can cause the drain field to fail because it can no longer treat and filter wastewater properly. To avoid these severe issues, stick to a regular pumping schedule and never skip a scheduled pumping.

4. 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.

5. Age

Unfortunately, one of the main causes of drain field failure is its age. A drain field has an average lifespan of about 25 years, so if your drain field is around that age, it might be on its last legs. When a drain field reaches the end of its life, you’ll need to call in a professional to either repair and renew the drain field. If that’s not an option, you might need to create a new drain field. If your drain field is failing and none of the other causes make sense, it might simply be old.
