Your drain field lines are an important part of your leach field, and for that reason, an important part of your septic system as a whole. At Atlanta Sewage-disposal tank Pros, our partner professionals install entire septic systems, including tanks and drainfields, and carry out regular maintenance for individuals, so their systems run correctly and can serve them for years without an issue. What Drain Field Lines Do? No matter what type of septic system you have, the effluent, or water from the tank, has to clear out somewhere. There are a lot of different options in this regard. Some let the effluent flow into a pit. Others recycle the effluent with a greywater recycling system. The most popular, however, is the leach field. With this setup, the effluent circulations through a series of underground pipes (drain field lines) that have great deals of tiny holes in them. These pipelines have the tendency to have a layer of rock or gravel around them, so the effluent can be quickly distributed into the surrounding soil, and a layer of soil and turf is positioned over the top. The drainfield, itself, plays a big role in cleaning the effluent, so it's safe for the environment. Germs that's naturally present will form a biomat, which slows the flow and gets rid of pathogens. There's also germs in the soil, so as long as the circulation of effluent remains slow, your on-site waste treatment center is healthy and safe for the environment, along with for individuals around it. You do need to take some safety measures to make sure that your drainfield can do its task.
