What is required for the filter fabric in an Absorption Field after installation?

The effective use of filter fabric in an Absorption Field relies on its proper placement and the environment it is designed to function in. Specifically, filter fabric is typically used to separate the gravel or crushed stone used in an absorption field from the surrounding soil. Backfilling the absorbed field with earth serves several important purposes.

When the filter fabric is backfilled with earth, it helps to protect the filter fabric itself from physical damage and prevents it from being easily disturbed by external forces. The backfilling process also facilitates proper water infiltration, as the soil layers help to distribute effluent more evenly and promote efficient drainage. Moreover, this method acts as a barrier to prevent soil from clogging the gravel, thereby maintaining the effectiveness of the absorption system.

This approach ensures that the absorption field functions optimally while simultaneously protecting the installed materials from erosion and other environmental impacts.
