Decommissioning a septic system

Septic Smart Oxford logo

Proper decommissioning methods will help ensure that our health, safety and environment are protected.

Septic tanks are full of untreated wastewater that is contaminated with bacteria, viruses, parasites and nitrates. If abandoned and not properly decommissioned, wastewater will eventually leak out, contaminating the soil, groundwater and pollute local watercourses.

Decommissioning your septic tank can also reduce the chance of a potential safety hazard. If not filled in with soil, an abandoned septic tank may collapse.

Please contact Public Health for more information about decommissioning your septic system.

Be sure to store your decommissioning records in a safe place. This documentation will be of value should you choose to sell your home in the future. Note: Septic Systems and their contents can be hazardous to you and those around you. Never enter or leave a tank open. For your safety it is highly recommended that you contact a licensed septic hauler, installer or service provider to conduct any work on your system.
