Cornerstone Excavation Services provides engineered septic system excavation, installation, and site preparation throughout Niles, Buchanan, Berrien Springs, Cassopolis, and surrounding Southwest Michigan communities.

Depending on the property and approved septic design, engineered systems can include several different treatment and dispersal methods, including:

  • Mound Septic Systems — Designed for properties with shallow soil, high groundwater, or other site limitations by elevating the treatment and dispersal area above natural grade.

  • Pressure Distribution Systems — Use a pump and pressure network to distribute effluent more evenly throughout the drain field.

  • At-Grade Septic Systems — Utilize a raised soil treatment area when conventional below-grade installation is not appropriate.

  • Sand Filter Systems — Provide additional wastewater treatment through a specially designed sand filtration system before effluent reaches the dispersal area.

  • Drip Dispersal Systems — Use small-diameter tubing to distribute treated effluent throughout a designated soil treatment area.

  • Aerobic Treatment Systems — Use oxygen and specialized treatment processes to provide additional wastewater treatment before dispersal.

  • Other Alternative or Engineered Systems — Site-specific solutions may be designed when property conditions require an approach beyond a conventional septic system.
