John A. Raber and Associates provides consulting services to aid in the selection of treatment technologies to:

  • Developers
  • Homeowners
  • Septic Designers

Our experience in failure diagnosis can be invaluable in determining the appropriate solution to overcome site limitations which may have created a failure. For new development, our knowledge of available technology has been recognized throughout the midwest. Choosing the right technology and being able to provide the local regulatory jurisdiction the right information and expertise in applications suited to a particular type of development may be the difference between a successful versus an unsuccessful project.
