Installation

Grade I through Grade IV septic installation

New construction, replacements and repair permits. We size, install and commission the system your soil and your county will actually approve.

Grade I

Conventional gravity systems

Standard tank and gravity-fed trench drain field for lots with suitable soil, depth and slope. The most common and most economical option.

Grade II

Pump to gravity & shallow placement

Used when the drain field sits above the tank or the best soil is shallow. Includes pump tank, effluent pump, controls and alarm.

Grade III

Low-pressure pipe (LPP)

Pressure-dosed small-diameter laterals that spread effluent evenly across shallow, restrictive or sloping soils.

Grade IV

Drip dispersal & advanced pretreatment

Drip irrigation fields, aerobic treatment units and sand filters for difficult lots, tight soils and reduced setback requirements.

How an installation runs

  • Site visit and soil evaluation with our Soil Scientist / AOWE
  • Percolation testing and permit package (Improvement Permit, then Construction Authorization)
  • System design sized to bedrooms, flow and soil loading rate
  • Excavation, tank set, line and field installation
  • Panel, float and electrical hookup where the system requires it
  • Health department inspection support and final grading
