Can I Relocate or Replace My Septic Tank?

Introduction

If you live in a rural area or a property that isn’t connected to the main sewer line, chances are you rely on a septic tank to manage your wastewater. But what happens if your tank starts to fail, or you’re planning major property changes? Many homeowners ask the same question can I relocate or replace my septic tank?

The good news is that yes, you can. Whether you are renovating, building an extension, or dealing with an older system that no longer meets modern standards, it’s possible to move or upgrade your tank safely and legally. In this guide, we’ll explore when relocation or replacement makes sense, the regulations you need to follow, and how Pro Septic Tanks can help keep everything running smoothly.

When Should You Replace or Relocate a Septic Tank?

There are a few common reasons why you might need to replace or move your septic tank. One of the most frequent issues is age. Most septic tanks last around 20 to 30 years, depending on maintenance and the materials used. Over time, the system can start to fail, causing slow drainage, unpleasant odours, or even contamination in your garden.

Another reason is property development. If you’re adding an extension, garage, or outbuilding, your existing tank might sit in the way of new foundations. In this case, relocation can be the ideal solution. Some homeowners also choose to upgrade to a more efficient system that meets the latest Environment Agency regulations, especially if the old tank discharges directly into a watercourse.

If your property lies within Dorset, Hampshire, or nearby areas such as Romsey or Wimborne, local ground conditions and drainage rules also play a big part in the decision.

Understanding Septic Tank Regulations

Before making any changes, it’s important to check that your septic tank complies with current UK regulations. Since 2020, tanks that discharge directly into streams, rivers, or ditches have been banned under the Environment Agency’s General Binding Rules.

If your tank falls under this category, you’ll need to either connect to a mains sewer (if possible) or replace your current system with a modern sewage treatment plant or soakaway. Pro Septic Tanks can carry out a professional septic tank inspection to assess compliance and help you choose the right solution for your home.

The Process of Relocating a Septic Tank

Relocating a septic tank isn’t just a case of digging a new hole and moving it over. The process requires careful planning, site assessment, and specialist installation work.

First, a professional will carry out a site survey to identify the best location for your tank, ensuring it meets all setback distances from buildings, boundaries, and water sources. Next, the old tank will be safely decommissioned, and a new system installed with modern components and proper drainage layouts.

Our Pro Septic Service team has handled many septic tank installations in Dorset and Hampshire, making sure every project meets local building control and environmental guidelines.
