Professional Onsite Septic System Design Services

Expert Sewerage Planning for Residential and Commercial Properties

Okanagan Septic & Excavation delivers comprehensive onsite sewerage design for both residential and commercial applications. Led by a certified Registered Onsite Wastewater Practitioner (ROWP), we engineer Type 1 and Type 2 septic systems capable of handling wastewater flows up to 9100L/day. We take pride in designing efficient, budget-friendly systems that meet your specific property needs while ensuring strict adherence to all provincial regulatory standards.

Why Expert Septic Design Matters

  • Regulatory Compliance: Our designs strictly utilize the BC Standard Practice Manual Version 3 as the primary guideline.
  • Cost Efficiency: We prioritize straightforward, gravity-fed systems first to prevent unnecessary equipment and maintenance costs.
  • Environmental Protection: Proper system engineering prevents groundwater contamination and ensures the long-term sustainability of your property.
  • Permit Approval: Accurate, certified sewerage plans are a mandatory requirement for obtaining local building permits.

Our Septic Design Methodology

  1. Site Assessment: We conduct thorough soil evaluations and site mapping to understand the specific geotechnical conditions of your property.
  2. Needs Analysis: We calculate your expected daily wastewater flow, accommodating residential or commercial requirements up to 9100L/day.
  3. Primary Engineering (Type 1): We always attempt to design the simplest solution first—a Type 1 septic tank utilizing gravity dispersal.
  4. Advanced Engineering (Type 2): If site conditions or flows require it, we seamlessly transition the design to a more complex Type 2 package treatment plant.
  5. Finalization: We provide you with complete, permit-ready design documents that balance your project goals with mandatory provincial standards.

Frequently Asked Questions

What is a Type 1 septic system design?

A Type 1 septic system is the most straightforward and cost-effective onsite sewerage solution. It consists of a standard septic tank combined with a gravity-fed dispersal field. Our philosophy is to always attempt to design a Type 1 system first, as it is the simplest to maintain and the most budget-friendly for the property owner.

When do I need a Type 2 septic system?

A Type 2 system, which utilizes a package treatment plant, is required when site conditions cannot support standard gravity dispersal. We move to a Type 2 design if your property has restrictive soil types, high groundwater, limited available space, or requires complex environmental safeguards.

What is the maximum daily flow your designs can accommodate?

We design onsite sewerage systems for both residential and commercial properties that produce daily wastewater flows up to 9100 liters per day (9100L/day).

Are your septic designs compliant with BC regulations?

Yes. All of our onsite sewerage designs use the BC Standard Practice Manual Version 3 as the strict operational guideline. Our certified ROWP ensures every plan perfectly aligns with provincial health and safety regulations.
