The Role of Septic Drain Fields Explained

septic_systemSeptic Drain Fields, also known as leach fields, serve a vital purpose in every septic system. The component is responsible for removing impurities and contaminants from the water that emerges from a septic tank. In a sense, it operates like a filter. The mechanics are different, but the end idea is similar.

The drain field consists of a series of perforated pipes installed in trenches one to three feet below ground level. Basically, the septic tank separates solid wastes from the water. The resulting wastewater (also known as the effluent) is transferred to the drain field where the soil acts as a natural filter by removing bacteria and other microscopic particles. The newly purified water then joins with the groundwater or is evaporated from the soil.

Symptoms of a Failing Drain Field

While generally maintenance-free, your Snohomish drainfield and septic system as a whole does need to be inspected periodically by a professional. This is especially the case if you notice any of the following symptoms:

  • Water puddles forming above the drain field
  • Soil collapsing on or near the drain field area
  • Sewage backup
  • Gurgling sounds in the plumbing

Depending on the extent of the damage, an entirely new septic system installation may be necessary. However, if the symptoms are diagnosed and treated early, most drain field failures can be addressed with an affordable repair.

Tips on How to Preserve Your Snohomish Drain Field

The following tidbits of advice will help protect and prolong the life and functionality of your septic drain field system:

  • Avoid using the ground above the drain field as a parking spot and refrain from placing heavy equipment or machinery over the area.
  • Do not plant trees or shrubs in your drain field. Overgrown roots can find its way into the pipes.
  • Do not pave over your drain field area with a hard surface, such as asphalt or concrete. Doing so will inhibit the soil’s ability to evaporate excess water.
  • Divert runoff water, such as those from the rain gutter, away from the drainfield.
