Where are the Septic Tank & Leachfield Usually Located on a Property & How are these components Laid-Out ?
The septic tank is usually located close to the building, perhaps just ten feet away, but on difficult sites a grinder pump may instead send wastewater to a more remote septic tank and drainfield. Incidentally, depending on where you live, the "drainfield" that absorbs & treats the final septic wastewater or effluent might be called a leachfield, leaching bed, drainage trench, soakaway bed or other terms. (Contact Us to suggest other septic system terms to include here.)
The principal components of a private on-site waste disposal system usually include the following:
Below is a simple sketch of a septic tank showing how solid waste leaving the building thorugh its main drain or wastewater piping or "sewer line" or "septic line" is retained inside the tank while liquid effluent flows to the drainfield. (Click images to see an enlarged version). Here are the main components of a septic system and a brief description of what each does:
Many variations on this general scheme are used, depending on local climate, soil conditions, available space, economy, and available materials. Special equipment and systems may be designed for problem or difficult sites such as rocky or wet ground, permafrost, or wet tropical marshlands.
