Professional septic services in Markham
The Oak Ridges Moraine and the headwaters that drain through Markham create high-water-table conditions in some neighbourhoods. Septic systems in these areas need particular care around tile bed sizing, effluent quality, and pumping frequency.
If your home was built before the early 1990s, your tank may be steel rather than concrete. Steel tanks rust through after roughly 25–30 years. A simple inspection can tell you whether replacement should be on the near-term plan.
