What This Software Does and Does Not Do

Read this before you buy. It is short, and it is honest.

What Ontario Septic Designer does

It calculates, checks, drafts, and organizes. You enter your bedrooms, fixtures, soil layers, T-times, water table, bedrock and setback distances. The software runs the Ontario Building Code Part 8 math, checks your distances against the right clearance tables, draws the cross-section, prices the materials, and prints the whole thing as a permit-ready package – organized the way a township or health unit expects to receive it.

What it does NOT do

• It does not issue permits. Only your local building department, health unit, or approval authority can do that. Nothing this software produces is an approval.
• It does not guarantee approval. A complete, well-organized package improves your odds of a smooth review. It does not decide the outcome. The reviewer does.
• It does not design for you. Ontario homeowners may design their own septic system on their own land – the property owner designs; the software calculates, checks, drafts and organizes. Professional users bring their own qualifications and judgment; the software does not replace either.
• It does not handle systems over 10,000 L/day. If your daily design flow exceeds 10,000 L/day, the workflow stops. Systems that size are outside ordinary small sewage system scope and need an engineer and a different approval path (MECP).
• It does not handle commercial or industrial projects. Restaurants, campgrounds, offices and other non-residential occupancies are outside the launch scope. The launch version covers residential Class 4 systems: conventional absorption trenches, filter beds, and raised versions of both.
• It does not replace an engineer where one is required. Some sites legitimately need engineered design. The software flags conditions that warrant professional review – take that flag seriously.
• It does not verify your site. The math is only as good as your measurements. Test holes, T-times, water table depths and setback distances must be verified in the field.
