Why is "mound height" significant in system design?

Mound height is significant in system design primarily because it plays a crucial role in ensuring adequate hydraulic head. The hydraulic head is the pressure that drives the effluent from the mound into the surrounding soil for proper treatment and absorption. A properly designed mound must achieve sufficient height to create the requisite pressure for effective dispersal of wastewater. This ensures that the effluent can penetrate the soil adequately, allowing it to be treated before reaching the groundwater table.

In systems where the height of the mound is insufficient, there may not be enough hydraulic pressure to promote proper leaching and distribution of the effluent, which could lead to inadequate wastewater treatment and possible environmental issues, such as surface runoff or groundwater contamination. Hence, designing a mound with the correct height is essential for both the effectiveness of the system and compliance with health and environmental standards.
