Cutting Your Lawn with a Septic System

Maintaining a well-manicured lawn is part of the American dream, but as a homeowner with a septic system, the dream can quickly turn into a potential maintenance nightmare if care is not taken. Your septic system is vital in keeping your home environment clean and healthy, but it's often overlooked in lawn care practices. In this extensive guide, we'll explore how to keep your lawn looking its best while safeguarding the longevity and efficacy of your septic system.

Understanding Your Septic System

Before we explore mowing practices, it’s important to understand how your septic system operates. Most residential septic systems include a septic tank and a drain field, also known as a leach field. The system allows waste from your home to separate into three layers inside the tank. The solids (sludge) settle to the bottom, the lighter waste forms a layer of scum, and in between these layers is a clear liquid called effluent.

This effluent is dispersed through the drain field, where it is further treated by bacteria in the soil. Maintaining a balance in the tank environment is key to a healthy septic system. Disrupting this balance, for instance, by compacting the soil around the drain field, can have unforeseen consequences.

Best Practices for Mowing Near a Septic System

Maintain a Safe Distance

One of the most important practices when mowing near your septic system is to keep a safe distance from components that extend above ground. The machinery weight and traffic on the surface directly affect the soil compaction, reducing the soil's ability to treat the effluent passing through it so please be mindful of heavy equipment if you use professional landscapers or substantial riding mowers. We advise establishing a zone over and extending at least 10 feet around your drain field where you only plant grass and no heavy machinery rolls over it. This area should also be free of any trees or shrubs with extensive root systems.

Mind Your Mowing Patterns

While not as impactful as mowing distance, mowing patterns can also affect your septic system. Mowing the same pattern repeatedly can cause soil compaction, similar to a well-worn footpath. Instead, change up your mowing pattern regularly to reduce the risk of soil compaction and allow for healthy grass growth.

Choose the Right Equipment

Opting for the right equipment can make a significant difference. Smaller, lighter mowers put less pressure on the ground and are less likely to cause soil compaction. Mowers with wider wheels can also help distribute the weight more evenly. We recommend using a push mower or a lawn tractor with large, turf-friendly tires.  When trimming or edging, be sure the blades or equipment you are using doesn't pose a threat to the components that are at or above ground such as the vent pipe (aka the candy cane), any clean-outs, or any ground level lids that are not buried.

The Impact of Grass Clippings on Your Septic System

Grass clippings, when allowed to remain around the drain field, can create a compost layer that impedes the soil's ability to treat effluents effectively. It’s important to mow your lawn so it doesn’t deposit clippings on the septic area and to bag or mulch your clippings to prevent them from washing into the system. Proper disposal of clippings is crucial for the overall health of your septic system.

Additional Tips for Lawn Care with a Septic System

Beyond the mowing itself, consider the broader aspect of lawn care and how it might affect your septic system.

Irrigation Considerations

Avoid overwatering your lawn, especially near the septic system. Excessive water can saturate the drain field, which hinders the effluent's ability to disperse and be treated. Monitor rainfall and adjust your sprinklers to match natural precipitation as closely as possible.

Fertilization Practices

Septic systems depend on healthy soil to function properly. While fertilizing your lawn is important, refrain from overdoing it. Excessive fertilization can stimulate fast, unhealthy growth that puts additional strain on the soil filtration process.  In addition to the impact on soil filtration, one of the leading ways to tell you have a failing drain field is by the plant's overgrowth near or over top of your drain field.  If you are fertilizing too much, you may not be able to tell any difference in the growth or color of your grass in this instance.

Landscaping around Your Septic System

The plants around your septic system play a role in maintaining the drain field's health. Choose shallow-rooted plants to prevent root invasion into the drain field. This reduces the risk of damaged pipes and soil compaction, allowing your septic system to operate at peak performance.
