Treatment Mound Systems

Raised Treatment Mound Fields

Treatment Mound Fields

The Raised Mound has the same components as the Pressure Distribution system or the At Grade septic system. The laterals are constructed on top of a thick sand layer which is imported and placed in the field location. Once all the component construction is completed the entire lateral area is covered over with a specific mix of sandy soil to create a long sloping mound structure. The effluent is then distributed over the entire surface area of the mound and is treated by the microbes within the sand layer.

There are strict criteria for the design of a mound based upon the soil characteristics of the ground which it has been built over.
