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

Septic tanks are full of untreated wastewater that can be contaminated with bacteria, viruses, parasites and nitrates. Wastewater will eventually leak out if the tank is abandoned which will contaminate the soil, groundwater and possibly pollute local watercourses. In some cases an abandoned septic tank can entirely collapse if not filled in with soil.

Professional decommissioning your septic tank will reduce the chance of creating a potential safety hazard. Here is our process:

Pump Out The Tank

It is important to pump the wastewater, as it contains bacteria and viruses that could make you or your family ill. Keep the pumping receipt as it acts as proof-of-pumping and will be required by Public Health as part of the approval process.

Pump Out The Tank
Fill

Fill in the tank with sand or gravel and put the access lid back in place or demolish the tank in situ. The soil around the septic tank should be slightly higher than ground level to allow for settling.

Send Proof

We will create a proof-of-pumping receipt with confirmation that your tank has been safely decommissioned so you can send a copy to the local council. The available space can then be considered for the new treatment tank to be installed.
