Wastewater Systems


The SJB Consulting Group has over 25 years experience with the investigation and design of on-site residential and commercial wastewater (septic) systems.  From conducting the field investigation to developing the final design package, our team of dedicated professionals works with both our client and the regulatory agency to ensure that the project meshes with your development plan and provides the necessary treatment to protect surface and groundwater resources.

On-site wastewater (septic) systems are designed to properly treat and dispose of domestic or commercial wastewater and are required for any parcel that is not connected to a community sewer system.  There are a variety of different types of systems that may be used to mitigate adverse site conditions located on a specific parcel.  Adverse site conditions may consist of any (or all!) of the following:  high groundwater (seasonal or permanent), shallow soil depth, limited area, nearby stream or seasonal drainage, etc.

The development of on-site wastewater systems is a phased process involving the property owner (or buyer), county regulatory agency and our design team.  The various phases of system investigation and design are:

  • Initial Consultation
  • Soil Profile Analysis
  • Percolation testing (when required)
  • Topographical Survey
  • Design Development

Once the system has been designed, it is submitted to the county for review and approval—at which point a permit may be obtained and the system installed.
