Safe Septic Tank Decommissioning
Professional Service for Exeter & East Devon

The process of decommissioning a septic tank must be careful and methodical to prevent future ground collapse. First, we arrange for all remaining liquid and solid waste to be safely emptied and removed from the site. We then thoroughly wash down the internal walls to eliminate any harmful bacteria and lingering odours.Once the tank is clean, we fracture the bottom of the structure to allow future ground surface water to drain away without pooling inside the chamber. Finally, we completely fill the void with an inert material like sand, gravel, or clean rubble, sealing the access points securely. This process guarantees the tank will never collapse or become a hazard.

An abandoned septic tank is far more than just a forgotten underground box; it is a serious hazard. Over time, the structural integrity of the tank will fail, leading to dangerous sinkholes appearing in your garden or driveway. Furthermore, if leftover waste is allowed to escape, it can cause severe environmental damage to local groundwater and soil.Decommissioning safely removes the risk of toxic gases building up inside the sealed chamber, protecting both humans and pets from immediate health risks. Dealing with a redundant tank correctly today is the absolute best way to safeguard your property and maintain its value for years to come.
