Soil Mapping:
Every wastewater project starts with a firm understanding of the governing soil types and geologic processes that made the land what it is today. Land Management Group (LMG) specializes in the initial mapping of soils and natural resources of the property in order to provide a "road map" for the client to use throughout the development process. It is not uncommon for our soils maps to be used to layout one hundred to three hundred lot subdivisions which we then manage throughout the wastewater treatment permitting process.
Subsurface Dispersal Systems:
LMG is well versed in working with the local and state health departments and in obtaining permits for residential or commercial septic waste application. For subsurface systems that exceed 3,000 gpd, Land Management Group performs computer modeling for the purpose of a hydrogeologic mounding analysis of wastewater using computer programs such as MODFLOW, DRAINMOD, & the Colorado State University mounding analysis. Land Management Group also performs special site assessments as required in T15A NCAC 18A .1970 to support pre-treatment systems.
Surface Dispersal Systems:
LMG routinely acquires wastewater dispersal permits for surface dispersal systems, many systems exceeding one million gallons per day (1 MGD), as permitted by the Division of Water Quality, Aquifer Protection Section. Land Management Group performs all aspects of the soils, agronomy, and geologic evaluations required for these projects including, soil fertility studies, nitrogen balance, phosphorus balance, water balance, hydraulic conductivity measurements (saturated and unsaturated zones), and sophisticated groundwater modeling with Visual MODFLOW.
Engineered Wastewater Systems (SC 610 Standard)
LMG can perform the requisite site work to support an engineer's design for a SC 610 Standard wastewater system on those sites that have soils that can not be permitted for conventional or other alternative systems.
