What septic system options do you offer?
South Jersey Engineers designs three types of septic systems to meet different property needs:
- Conventional Gravity-Fed Systems – Our specialty and the most common choice for South Jersey properties. These reliable, low-maintenance systems use natural gravity to move wastewater through your septic tank and drain field.
- Advanced Treatment Units (ATUs) – Required for properties with specific site constraints or environmental concerns. ATUs use aerobic bacteria and mechanical components to provide enhanced wastewater treatment.
- Mound Systems – Designed for properties with high water tables, shallow soil, or bedrock close to the surface. These raised drain field systems are built above the natural soil level to ensure proper wastewater treatment.
