In this guide, we'll walk you through everything you need to know about drain field maintenance and cleaning. Let's help you save your septic system and avoid costly replacements!

Understanding Your Septic Drain Field

Before jumping into cleaning methods, let's understand what we're working with:

What Is a Septic Drain Field?

A drain field (also called a leach field) is the final stage of your septic system. According to the EPA, it consists of:

  • Underground perforated pipes that release wastewater into soil

  • Gravel or aggregate surrounding these pipes

  • Soil that filters the wastewater naturally

Common Drain Field Problems

Your septic drain field might need cleaning if you notice:

  • Standing water or soggy areas above the drain field

  • Slow-draining fixtures throughout your home

  • Sewage odors in your yard

  • Unusually lush, green grass over the drain field area

Can You Clean Out a Septic Drain Field?

The short answer is yes, but with important caveats. According to NESC at West Virginia University, there are several effective ways to clean and restore drain fields, but the right method depends on what's causing the problem.

How to Clean Septic Drain Field: Professional Methods

For serious problems, these professional methods are most effective:

1. Jetting

Hydro-jetting uses high-pressure water to clear clogs:

  1. A professional inserts a specialized hose into your drain field pipes

  2. Pressurized water blasts away biomat (slimy bacterial buildup) and other blockages

  3. The debris gets flushed back into the septic tank for later pumping

National Environmental Services Center notes that jetters operate at 1000-4000 PSI and should only be used by trained professionals.

2. Aeration Treatment

This method adds oxygen to help healthy bacteria thrive:

  1. A pro installs an aerator in your septic tank

  2. The aerator pumps oxygen into the system

  3. Aerobic (oxygen-loving) bacteria multiply

  4. These bacteria break down waste more efficiently

A study by Purdue University found that aeration can extend drain field life by up to 10 years!

3. Chemical Treatments

Special bacterial and enzyme treatments can help:

  1. A technician adds biological additives to your septic system

  2. These compounds break down the biomat clogging your drain field

  3. Treatment continues over several weeks or months

The National Onsite Wastewater Recycling Association recommends using only products specifically formulated for septic systems.

DIY Methods: How to Clean Septic Drain Field Yourself

For less severe problems, these DIY methods might help:

1. Reduce Water Usage

Give your drain field time to dry out:

  1. Fix all leaky faucets and toilets immediately

  2. Install water-saving fixtures throughout your home

  3. Spread out laundry loads over several days

  4. Take shorter showers

Water.org reports that reducing household water use by 30% can significantly improve septic function.

2. Biological Additives

Some over-the-counter products can help:

  1. Purchase a septic-specific enzyme or bacterial treatment

  2. Follow package directions exactly

  3. Flush the treatment down your toilet

  4. Repeat as directed on the package

The National Environmental Health Association cautions to only use products labeled specifically for septic systems.

3. Drain Field Rest and Rotation

If your system has multiple drain fields:

  1. Locate the diverter valve (usually near the septic tank)

  2. Switch to the alternate drain field

  3. Allow the problematic field to rest for 6-12 months

  4. The natural soil bacteria will break down the biomat during this time

What NOT to Do to Your Drain Field

Avoid these common mistakes:

  • Never drive or park vehicles on your drain field

  • Don't plant trees or shrubs near the drain field area

  • Avoid using a rototiller on the drain field

  • Never direct rainwater drainage toward your drain field

  • Don't use harsh chemicals like bleach or antibacterial soaps excessively

According to Cornell University, physical damage to drain field soil structure is often irreversible!

When to Call a Professional

Some situations require expert help:

  • Standing sewage on your lawn

  • Multiple backed-up plumbing fixtures

  • System hasn't been inspected in over 3 years

  • Home was recently purchased with unknown septic history

The National Onsite Wastewater Recycling Association maintains a directory of certified septic professionals.

Preventative Maintenance Tips

Keep your drain field healthy with these practices:

  • Have your septic tank pumped every 3-5 years

  • Install an effluent filter on your septic tank

  • Use septic-safe toilet paper

  • Avoid flushing anything besides human waste and toilet paper

  • Get professional inspections every 1-3 years

Conclusion

So, can you clean out a septic drain field? Yes, through professional methods like jetting and aeration, or DIY approaches like reducing water usage and using biological additives. The key is addressing problems early before they become severe.

Remember that prevention is always easier than repair. With proper maintenance and care, your septic drain field can function properly for decades. We hope this guide helps you maintain a healthy septic system and avoid the stress of major repairs!
