What role do plants play in a drain field?

Plants play a vital role in the functionality of a drain field by assisting in absorption and providing additional filtration. The root systems of plants help to absorb excess moisture from the soil, which aids in preventing surface water saturation and promotes effective wastewater treatment. As water passes through the soil, it encounters plant roots which can capture nutrients and contaminants, contributing to the filtration process. This natural interaction enhances the overall treatment of effluent before it reaches the groundwater, ensuring that harmful substances are minimized. The presence of vegetation also helps to stabilize the soil and prevent erosion, fostering a healthier ecosystem within the drain field area.
