The SJB Consulting Group is a full-service environmental consulting firm specializing in on-site wastewater (septic) systems. Our design team specializes in applied wastewater solutions for individual residences, land development projects and small communities throughout Central California, including Alameda, Amador, Alpine, Calaveras, Contra Costa, Sacramento, San Joaquin, Stanislaus and Tuolumne Counties.


The SJB Consulting Group has over 30 years of 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 our surface and groundwater resources.

IN A NUTSHELL… 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, a 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:

  • Conceptual Site Development
  • Soil Profile Analysis
  • Percolation testing (when required)
  • 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.
