Detailed Description Of Services We offer 

• Tri-Lakes Contracting provides complete septic system installation throughout Colorado’s mountain communities. From standard gravity-fed systems to advanced engineered treatment units, we manage the entire process from feasibility studies to final approval.
• Pre-Purchase Septic Feasibility Reports – Before you buy property, we provide comprehensive evaluations to help you make a smart investment. Our service includes:
• On-site assessment of soil conditions, terrain features, and setback limitations that may affect septic design
• A drone survey with photo documentation for a clear view of the property
• A written feasibility report with rough pricing estimates so you understand potential installation costs up front
  This ensures you won’t be caught off guard by unexpected expenses and can make an informed decision before purchasing land.
• Soil Testing & Site Evaluation – We dig and prepare test pits so engineers can design the right septic system for your property. We also facilitate soils and foundation reports through our engineering partners, required for both property purchases and permitting.
• System Design Support & Site Plans – We work hand-in-hand with licensed engineers to ensure your septic system is efficient, durable, and fully code-compliant. As part of a turnkey design package, we facilitate engineer-prepared site plans that show proposed well locations, setbacks, property boundaries, and utility layouts — everything required for permitting.
• Permitting & Paperwork – We coordinate all necessary documents and secure septic permits, streamlining the process with your county.
• Materials & Technology Management – We source and install advanced septic solutions, including:
• Polyurethane septic tanks – lightweight, durable, and long-lasting. Unlike concrete tanks, they don’t leak mud and are much easier to handle.
• Advantex® and Orenco® Advanced Treatment Units (ATUs) – higher-level treatment units that reduce setback requirements, ideal for smaller or challenging properties.
• Soil Treatment Areas (STAs) – engineered with ASTM C-33 sand filters for dependable, long-term performance.
• Discharge Laterals & Drainfields – precision-installed for proper flow and maximum lifespan.
• System Options – We install both gravity-fed systems (cost-effective and reliable) and pump / time-dose systems (engineered for properties that require elevation changes or timed dosing).
• Excavation & Installation – Tanks, piping, risers, cleanouts, drainfields, and soil treatment areas installed with precision and care.
• Inspection Coordination – We work directly with engineers and county inspectors to ensure every installation is built correctly and passes approval the first time.
• Backfill & Grading – After approval, we carefully backfill, grade, and restore the site for stability and proper drainage.
   

Whether your property requires a straightforward gravity-fed system or a complex advanced treatment unit with engineered STAs, Tri-Lakes Contracting has the expertise, equipment, and licensing to deliver a septic system that’s built to last.
