🔬🌱 Septic Science Saturday: What Is a Drain Field?
You know about your septic tank—but what happens to the wastewater after it leaves the tank?
Meet the drain field!
The drain field is an underground area where wastewater from your septic tank is distributed through pipes and slowly filters through the surrounding soil. The soil helps naturally treat the wastewater before it moves deeper into the ground.
That means what happens above your drain field matters, too! Avoid parking vehicles, building structures, or planting trees with deep roots over the area, as they can damage your septic system.
💡 Septic Science Tip: Knowing where your drain field is located is an important part of being a septic-smart homeowner.
