Register a septic tank or other private sewage treatment system
If you're not on the mains sewer you probably use a private sewage treatment system, such as a septic tank.
This will discharge to land or water and could cause pollution. By law, it must be registered.
You must have a sewage treatment system in place, such as a septic tank or package treatment plant.
You should ask us to check if you’re not sure whether your treatment system is already registered. If it is and you register it again, we can’t offer a refund.
You can only use this online service if the treatment system:
- is more than two years old; and
- serves between one and nine properties.
To register online, you’ll need to:
- select the address of all properties that use the treatment system; and
- provide a one-off payment of £151*.
Please contact us if you do not have a sewage treatment system in place, or if it is:
- less than two years old;
- serves more than nine properties;
- near Loch Leven in Fife;
- near the Lunan Lochs;
- near Dhoon Bay;
- near Ayr (South).
Due to the cyber attack we can only process applications where authorisation is required within three weeks.
