What does "filled land" refer to in sewage disposal contexts?

"Filled land" in sewage disposal contexts refers to areas where more than 2 feet of soil and/or debris has been added. This can occur for various reasons, such as land reclamation or construction projects where soil has been elevated, often leading to a change in the natural drainage and absorption capabilities of the land.

In the context of septic systems, filled land can pose significant challenges for sewage disposal because the characteristics of the added fill can differ greatly from the native soil. These differences can affect the performance of a septic system, as natural soil properties are essential for properly absorbing and filtering wastewater. Understanding these implications is crucial for installers to ensure that septic systems are placed in locations that will function effectively and comply with health regulations.
