In our service area, a residential septic tank installation typically ranges from $6,000 to $12,000. This cost is influenced by factors such as tank size, material, site accessibility, and any additional components required for the complete septic system. Keep in mind that the septic tank is just one part of the overall system, which must meet the standards of Part 8 of the Ontario Building Code (OBC).
Repair vs. Replacement
If you suspect your septic tank may need replacing, consider contacting our office first. Many tanks that have not suffered structural failure can be repaired at a fraction of the cost of a full replacement. Proper maintenance, timely repairs, and regular inspections can extend your system’s service life and ensure ongoing compliance with OBC Part 8 regulations.
Reasons for Replacement
Septic tanks may need to be replaced due to age, material fatigue, or mechanical damage. New installations are also common when building a new home or upgrading an older system. In either scenario, selecting the right tank type and ensuring proper installation will help maintain efficiency, protect the environment, and prolong the life of your septic bed.
Tank Materials: Precast Concrete vs. Plastic
Two common septic tank materials in Ontario are precast concrete and plastic. If the job site offers good accessibility, precast concrete is often the most cost-effective and durable long-term choice. It is environmentally friendly, strong, and less prone to shifting.
For sites with restricted access, lightweight plastic tanks provide a practical and permanent solution. They are easier to transport and install where space and equipment access are limited, while still offering reliable, code-compliant performance.
