Are embankments required to be constructed from impermeable compacted material?

The statement is true because embankments built for septic systems must be constructed from impermeable compacted materials to ensure that water does not infiltrate or escape through the structure. This is critical in maintaining the integrity of the system and preventing contamination of groundwater. Impermeable materials help in controlling water flow and ensuring that effluent remains within the designated areas, thus facilitating proper functioning and compliance with regulations. By utilizing compacted impermeable materials, the risk of failure in the septic system is minimized, promoting effective waste management and environmental protection.

Alternatives like the idea that embankments may not always require impermeable materials could lead to issues such as erosion or the leaching of contaminants into surrounding soil and water sources. Therefore, adherence to standards which specify the use of impermeable materials is essential for the safety and effectiveness of septic system installations.
