I’ve been looking into septic system design specifically for properties around Calgary, and it quickly became clear that it’s not a one-size-fits-all process. Soil type, groundwater levels, lot size, and local regulations all seem to play a major role in how a system should be planned. What surprised me is how much the design can change depending on site conditions. For those with experience in this area, which factors tend to cause the most design challenges? And what do homeowners often underestimate when planning a septic system in this region?
