Why Septic Tanks Are Replaced

There are several reasons why a septic tank may need to be replaced:

  • Your tank discharges into a watercourse, such as a ditch or stream
  • The tank is damaged, leaking or no longer functioning effectively
  • It does not meet the Environment Agency rules introduced in 2020
  • You are planning to sell your property and need to demonstrate compliance

If any of these apply, we can carry out a full inspection to assess your current system and provide clear, practical recommendations.

What the Replacement Involves

Drain Division manages the full process from start to finish. Here’s what you can expect:

Initial inspection
We carry out a CCTV survey and system check to understand the current condition and layout.

Advice and planning
We explain your options clearly and recommend the most suitable replacement, whether a reconfiguration or a new sewage treatment plant.

Removal and installation
We remove your existing tank and install a modern, compliant treatment system that meets BS EN 12566-3 standards.

Final checks and handover
Once installed, we ensure everything is working correctly, provide supporting documentation and leave your site clean and tidy.

A Legal and Environmental Requirement

Since 2020, it has been illegal to discharge directly from a septic tank into surface water. If your tank is doing this, you are not compliant and may face enforcement action. Replacing the system with a modern sewage treatment plant avoids this risk and improves overall efficiency.

We understand the regulations and take care of the compliance side so you don’t have to. Whether you are preparing to sell your property or fixing an ongoing problem, we can help you get it sorted quickly and professionally.
