Septic Installation

New systems built right the first time.

Colorado Regulation 43 governs all onsite wastewater treatment systems (OWTS) in the state, and every installation Southwest Septic performs is designed and permitted to meet it. Reg 43 sets the rules for site analysis, system design, setback distances, soil treatment area sizing, and installer licensing -- and in La Plata County those requirements are enforced at the local level before a permit is issued. When a site requires an engineered design, we can help connect you with a qualified engineer and coordinate through the process.

  • Site analysis and soil evaluation per Regulation 43
  • Permit coordination with La Plata County and CDPHE
  • Conventional and mound system installations
  • Reg 43-compliant setbacks from wells, water features, and property lines
  • Frost-depth installation for Colorado's freeze-thaw conditions
  • Final county inspection and system walkthrough
