Designing the mound component is described here in a 15-step process. The wastewater distribution design steps are described in Bulletin 829, Mound Systems: Pressure Distribution of Wastewater. The configuration of the mound is based on the volume of the wastewater to be treated, the characteristics of the natural soil, and the depth to the limiting condition.
The following pages describe the design processes and work through an example of a system for a three-bedroom home.
