Understanding Septic Fields
Before we dive into the world of planting on top of a septic field, it’s essential to understand how septic systems work. A septic system is a self-contained wastewater treatment system that uses natural processes to break down and treat wastewater. The system consists of a septic tank and a drainfield, also known as a leach field or septic field. The septic tank holds the wastewater, allowing solids to settle to the bottom and scum to rise to the top. The treated wastewater then flows into the drainfield, where it’s dispersed into the soil and filtered by the soil’s natural bacteria.
How Septic Fields Work
The septic field is a critical component of the septic system, as it’s responsible for filtering and purifying the wastewater. The field is typically made up of a series of perforated pipes and gravel, which allow the wastewater to seep into the soil. As the wastewater flows through the soil, it’s broken down by the soil’s natural bacteria, removing harmful pathogens and nutrients. The purified water then flows into the groundwater, where it can be used by plants and eventually make its way into nearby streams and rivers.
Potential Risks of Planting on Top of a Septic Field
While planting on top of a septic field can be a great way to create a beautiful landscape, there are some potential risks to consider. One of the main concerns is the risk of contaminating the soil and groundwater with bacteria and other pathogens from the septic system. If the plants’ roots grow too deep, they can penetrate the septic field and come into contact with the wastewater, potentially spreading disease-causing bacteria. Additionally, if the soil becomes waterlogged or compacted, it can reduce the effectiveness of the septic system, leading to backups and other problems.
Choosing the Right Plants
When it comes to planting on top of a septic field, it’s essential to choose plants that are well-suited to the conditions. Plants with deep roots or those that require a lot of water should be avoided, as they can cause problems with the septic system. Instead, opt for plants with shallow roots and low water requirements. Some good options include:
- Grasses, such as buffalo grass or blue grama grass, which have shallow roots and can thrive in dry conditions
- Wildflowers, such as black-eyed susans or cosmos, which have shallow roots and can add a pop of color to the landscape
- Groundcovers, such as creeping thyme or sedum, which have shallow roots and can help to prevent erosion
Soil Quality and Preparation
Soil quality is critical when it comes to planting on top of a septic field. The soil should be well-draining and have a pH between 6.0 and 7.0, which is slightly acidic to neutral. If the soil is too dense or poorly draining, it can cause problems with the septic system. To prepare the soil, start by testing the pH and nutrient levels. Based on the results, add amendments such as compost or fertilizer to adjust the pH and nutrient levels. It’s also a good idea to add a layer of organic mulch, such as wood chips or straw, to help retain moisture and suppress weeds.
