What is a drainfield? A drainfield is sometimes called a leachfield or absorption field. It is a network of pipes, trenches, gravel and soil. The pipes are perforated to allow wastewater to drip and flow through. They are laid inside of trenches or beds that are filled with gravel, which is also part of the filtration process. Soil surrounds the entire drainfield area and works in other ways to help your septic system work effectively.
Once it reaches the drainfield, the wastewater trickles out of the pipes and passes into the gravel layer. Then it passes on down into the soil, which is where filtration happens on a micro level. The soil actually filters the wastewater like a composting system, passing through the various pore-like spaces within the soil. This is where the soil microbes go to work, treating the wastewater before it enters the ground water supply. Soil that is dry, permeable and rich in oxygen that is located below the actual drainfield is best suited for this process and will yield the most positive results.
How to Take Care of Your Drainfield

Keep excess water away from your drainfield such as drainage ditches, irrigation systems, runoff from roofs in storms or draining hot tubs and pools.
