The final treatment and dispersal component of an on-site wastewater treatment system spreads the effluent into or onto the soil with the intent of accepting the effluent and removing the remaining contaminants from the effluent. The process for designing the system includes evaluation of the soil's capability for providing contaminant removal and acceptance of the effluent. An appropriate distribution method is then selected for dispersing the effluent into the soil.

The soil treatment capability, distribution system, and distribution system elevation function together to provide final treatment and dispersal of the effluent. These components and the concepts behind them guide the function and performance of the treatment system.
