Our Process For Septic Designs

Step 1: A Full Development Evaluation

We will do a full development evaluation of:

  • Your home

  • Your office building

  • Your restaurant or other development

We'll analyze and calculate estimated flows and wastewater strength.

Step 2: A Full Site Evaluation

  • Soil test pits

  • Soil sampling

  • Lab reports

  • Site constraints

  • Setback evaluations

Step 3: An Explanation of the Onsite Soils

Once we receive the lab results back with the soil sample results, we will be more than happy to offer an explanation of the onsite soils at your home, restaurant, or business, and how they affect the size and type of septic system options that you will have.  

Step 4:  A Complete System Layout

After we provide an onsite soil explanation, we will discuss with you the various options you have for your septic system design.  We will explain the estimated layout, footprint, and maintenance expectations of the proposed system for your home, office building, or restaurant in Alberta.

Step 5: A Look at Required Components

At this stage, we will provide your home, restaurant, or business with a look at the recommended and required components such as:

  • Septic tanks

  • Pumps

  • Filters

  • Pipe sizing

Step 6: A Document Showing Calculations

Part of the design document includes our calculations and worksheets explaining how we arrived at our estimated flows and strengths.  These calculations are required to complete a full design, as well as for the permitting authorities.

Step 7: A Full System Certified Septic Design

A Certified Design report will be finalized, which includes all of the components listed above.  The document, usually between 50-80 pages, can now be used to get an accurate quote from a certified installer.  The Certified Design report is required  and will be used as part of the permitting paperwork with the local jurisdiction once you have chosen your installer.  

Step 8: A Full System Summary Sheet

A full system summary sheet is included in the Certified Design report.  This is very helpful for a quick reference and overview for both certified installers and Safety Codes Officers (inspectors).  

Step 9: A Septic Design Permit Approval

All Certified Septic System Designs come with 100% guarantee that it will be approved by the local permitting authority.  If there is a problem during the permitting process, we will fix it at no charge.
