Engineering Services

  • “Sanitation in Subdivision” submittals to the Montana Department of Environmental Quality (MDEQ), Missoula City-County Health Department (MCCHD), Ravalli County Environmental Health Department (RCEHD), Lake County, Granite County, and Mineral County – A “subdivision review” is necessary when a property line is proposed or shifted from its previous location.  Even a 5 foot shift of a boundary will trigger a “Sanitation in Subdivision” review per Montana Code Annotated (MCA) 76-4.  Whatever the process, Family Transfers, Boundary Line Relocations (BLR), Aggregations, Subdivisions, or Lifting of Sanitation Restrictions, our engineering services will help you make the most of your property.
  • Certificate of Subdivision Approval (COSA) rewrites and Modified Site Plans (MSP) through state and county review – If your land has previous DEQ approval, but needs to be adjusted to allow you to develop, we will work with you to find solutions.        
  • Septic Permits and Site Evaluations for County Health Departments – This process can include soil profiles, percolation tests, Non-Degradation analysis, Adjacent to Surface Water analysis, pressurized and gravity septic system design, site map preparation, and preparing and submitting the proper permit paperwork. We will work with you to satisfy the county requirements and get the appropriate system approved for your situation.
  • Feasibility studies of building, septic, and water system siting – We will help you assess the practicality of proposed development, and help identify potential benefits and roadblocks as you move toward your vision. This can be particularly helpful when contemplating purchasing a property.
  • Percolation Tests and Septic Design per county requirements – Percolation “Perc” Tests may be required to determine if soils are suitably permeable for a septic system. Additionally, we can design a pressurized conventional system, Level 2 advanced treatment system, or analternative septic system that is specifically tailored to your site limitations and circumstances.
  • Residential and Commercial Site Plan Check Lists for city and county Building Permits – Detailed Site Plans may be required for building permits and will provide detailed plans of the structures and surroundings. We will provide plans sheets with elevations and benchmarks to help verify that development codes are being met and your construction is carried out properly.   
  • DEQ and city/county review of sewer main and water main extensions – A utility “main” is any line providing water or sewer to multiple (2+) service connections, any line serving a water hydrant that is designed for firefighting purposes, or any line that is designed to water or sewer main specifications. The approval process for these projects includes the completion and submittal of DEQ and city/county checklists, preliminary review, city/county/DEQ approval, construction inspection, and project closeout.  Our engineers will guide your project every step of the way.
  • Groundwater monitoring for septic feasibility – Septic systems must have 4’ of vertical separation from the highest seasonal groundwater on site. The analysis of soil profiles and the submittal of groundwater monitoring applications will help ensure the practicality of continuing your project
  • Mapping of groundwater flow directions – On-site static water level surveys (conducted per DEQ procedures) of the surrounding wells can help determine the best possible location/course of action regarding your septic system.
  • Water quality testing for new or existing wells – Testing for contaminants such as bacteria, nitrates, arsenic, and other constituents is recommended by the National Ground Water Association (NGWA), may be required for various permits, and can put you at ease about your drinking water.
