Our Septic System Services Include:

📝 Design Packages for Health Authority Approval

• Detailed site plans showing topography, setbacks, and system layout.
• Review of soil analysis and percolation rate data.
• Accurate system sizing and component specifications (tanks, fields, etc.).
• Clear layout drawings and specific installation notes for contractors.
• Design rationale, supporting calculations, and required documentation.

All designs are completed in accordance with the BC Sewerage System Regulation and applicable Health Authority guidelines.

System Types We Design:

• 💧 Type 1 Systems: Standard septic tank and gravity-fed dispersal field systems for suitable soil conditions. A cost-effective and straightforward solution for many rural and semi-rural properties.
• ⚙️ Type 2 Systems: Treatment systems that provide additional filtration and oxygenation before effluent reaches the dispersal field—ideal for smaller lots, challenging soils, or environmentally sensitive areas.
• 🔬 Type 3 Systems: Advanced treatment systems with mechanical and/or biological components designed for high-level performance, tight setback conditions, or when discharging to surface water is required.

Construction & Installation Support

We don't just hand over the drawings—we work with installers and contractors during the construction phase to ensure the system is implemented exactly as designed. Our team is available for site reviews, coordination with local officials, and construction support as needed.
