Which of the following configurations can ensure no hump remains in the yard after septic tank installation?

Choosing a low profile septic tank or adding extra fill soil around a regular tank is an effective strategy to prevent humps from forming in the yard following septic tank installation. A low profile tank is designed to sit closer to the ground surface, which minimizes the amount of earth that needs to be moved or disturbed during installation. This can lead to a flatter surface afterwards because there’s less soil to compact or settle, thus reducing the likelihood of any uneven settling that leads to humps.

Additionally, when extra fill soil is used around a standard septic tank, it allows for the adjustment of the landscape to better match the natural grade of the yard. This fill soil can be carefully contoured and compacted to ensure that no additional mounds form as it settles over time. This approach not only provides the necessary depth for the septic tank but also enhances the aesthetic and functional aspects of the yard by creating a smooth, level surface.

In contrast, using a regular tank with improper placement can lead to complications, including inadequate drainage or the disruption of the surrounding area. Relying solely on fill soil with grading may not provide sufficient coverage or stability, potentially resulting in uneven surfaces. Lastly, burying the tank deeply in the ground may lead to excessive soil movement and settling
