Trusted Septic Installation in Duluth, Hermantown, Esko & Aurora, MN

Your septic installation begins with a comprehensive site assessment that evaluates soil composition, water table depth, and property slope-critical factors in Minnesota's varied terrain. Percolation tests determine how quickly water drains through your soil, which dictates tank size and drain field design. Once permits are secured, excavation begins with careful attention to frost depth requirements that protect your system during harsh northern Minnesota winters.

During installation, Semper Fi Excavation, LLC positions the septic tank at the precise grade needed for gravity flow, connects inlet and outlet pipes, and constructs the drain field with properly spaced lateral lines. The crew ensures each component meets or exceeds code standards.

After backfilling and compacting soil around the tank and distribution pipes, a final inspection confirms everything functions correctly. You'll receive documentation of your system layout, maintenance recommendations, and pumping schedules tailored to your household size and water usage patterns.
