True or False: Gravelless seepage systems must have a specific type of separation material placed prior to backfill.

Gravelless seepage systems are designed to manage wastewater without the use of gravel, utilizing alternative materials to enhance filtration and drainage. In these systems, it is not mandatory to use a specific type of separation material prior to backfilling. The design and regulations for gravelless systems allow for flexibility in the materials used, depending on the specific conditions and local regulations.

The lack of requirement for a certain type of separation material means that the installation can adapt to various soil types and environmental conditions, promoting better performance in a wide range of settings. This adaptability is a key advantage of gravelless systems, ensuring they can be effectively employed in diverse scenarios without stringent requirements for specific materials.
