- 1.Septic systems: underground settling tanks and subsurface leach fields. Diligence: soil percolation capacity, tank pumping logs, and reserve replacement field area.
- 2.Wastewater lagoons: open-air stabilization ponds relying on aerobic digestion and sunlight. Diligence: berm and dike integrity, surface aerator functionality, current state discharge permits.
- 3.Package treatment plants: compact mechanical mini-treatment facilities requiring daily oversight, licensed operators, and ongoing testing.
Key Takeaway
Private sewer systems require comprehensive environmental compliance checks, reserve land verification, and active maintenance contracts.
