Safe Septic Tank Decommissioning
Serving Exmouth, Sidmouth & East Devon

Safely retiring an old tank is a structured process that requires precision to protect both your property and the local environment. Here is a look at exactly how we carry out our comprehensive service:Emptying and Cleaning: First, we ensure all liquid and solid waste is completely pumped out and responsibly disposed of. This guarantees no harmful gases or dangerous bacteria escape during the work.Breaching the Base: If the tank is staying in the ground, we puncture the base. This stops rainwater from pooling inside and creating a stagnant hazard.Filling the Chamber: We carefully fill the empty tank with inert materials like sand, gravel, or crushed rubble. Filling it correctly ensures the ground above remains stable for years to come.Removing the Tank: In some cases, removing the tank entirely is the best option, especially if you need the land for a new extension. We can excavate and safely dispose of the old unit.

It might be tempting to just disconnect an old system and forget about it, but leaving a buried tank untreated is incredibly dangerous. Over the years, the structural integrity of old tanks will naturally weaken. If the lid decays or the walls collapse, a deep void is left in your garden, posing an immediate physical hazard to children, pets, and even heavy landscaping equipment.Furthermore, if liquid waste is left inside, it produces highly toxic, harmful gases. If these gases escape, they become a serious health risk to your family and your neighbours. Even if you no longer use the system, as the property owner, you are legally responsible for its safety. Having it professionally decommissioned immediately gives you absolute peace of mind.

Whether you are in leafy Clyst Heath or right on the coast in Exmouth, your drainage work must comply strictly with local and national regulations. When upgrading, decommissioning an old system must align with the Environment Agency General Binding Rules to prevent local groundwater contamination.We are highly experienced with the diverse local geography across Devon. From managing high water tables in Exmouth to navigating building control requirements set by Exeter City Council and East Devon District Council, we ensure every step is fully compliant.

This is one of the most common questions homeowners ask. For most properties, safely cleaning and filling the tank with sand or stone is the most straightforward and cost-effective solution. It prevents ground collapse and ensures no harmful gases escape, all without the need for heavy, disruptive excavation work.However, if your old tank sits directly where you plan to build a new conservatory, garage, or driveway, entirely removing it is necessary. Before any work begins, we can carry out comprehensive septic tank surveys to assess the exact condition and location of your existing system, helping you make the best, most informed decision for your property.
