Septic Mound

Mound Septic Systems are a wastewater absorption trench system which has been constructed using suitable soil which has been placed on top of the natural soil on a building lot.

Unfortunately, in areas soils with shallow depth over a limiting layer or soils with a high percolation rate make it impossible to use a conventional subsurface soil absorption system for wastewater treatment and disposal. On these problem sites, mound systems may be an alternative.

Proper siting and design is always critical in the consideration of septic tank-mound systems. Ensuring that these systems are properly sited and designed takes on extra importance to the entity providing long-term management.
