Your septic system is not just made up of your septic tank. Your plumbing, your tank, and your drain field are all essential parts of your system. Your septic system drain field is located near your septic tank and filters wastewater created by your system. To properly care for your drain field, it’s important to understand how your drain field works and why it’s important. We’ve broken down everything you need to know below.
Your 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.
Your drain field is an essential part of your septic system. Once wastewater travels out of your home and into your septic tank, your tank releases it into the drain field. The drain field is then responsible for filtering the wastewater and releasing it into the ground as clean groundwater. Without a functioning drain field, your groundwater can become contaminated, putting your health and safety at risk, as well as the plants and wildlife in your area. In order to function properly, your drain field needs to be comprised of the proper type of soil.
Types of Soil
Clay soils are not ideal for drain fields because they do not provide enough room for effluents to easily flow through. This density will create drainage issues in your yard and backups in your septic system. Clay soils typically bond to sodium molecules in wastewater, blocking the effluent from draining properly. Over time, this bonding can lead to drain field failure.
Soils made up primarily of gravel or other course materials are too course and will cause the effluent to pass through too quickly. When the effluent passes through at this rate, it will not be filtered at all. This lack of filtration can contaminate your water supply and cause issues in your yard. This unfiltered effluent will cause waste buildup in your yard and toxic smells.
The best type of soil is a happy medium between clay and gravel that is not too dense or too loose. The mixture of the two will allow the soil to filter the effluent while draining properly and keeping the septic process functioning properly. In order to ensure ideal filtration, there needs to be a good balance of course and fine soil.
