Do you Need Planning Permission to Install a Sewage Treatment Plant?

If you are:

• Replacing an old septic tank,
• Installing a treatment plant in roughly the same position,
• Serving a single dwelling.

You often do not need full planning permission.

But you must comply with:

• Building Regulations,
• Environment Agency General Binding Rules.

Planning permission may be needed if:

• It’s a new installation for a new property,
• The discharge point changes significantly,
• The property is in a protected area,
• The system is close to a watercourse,
• The installation is part of a larger development.

Local authorities vary.

Always check with your local planning department before installation.

Before installing:

1. Check planning requirements,
2. Check Environment Agency rules,
3. Get a proper site survey,
4. Ensure the system is sized correctly,
5. Ensure proper gradient and discharge.

If you’re unsure, it’s always better to get advice before digging.
