Septic Tank Compliance – Frequently Asked Questions

Common questions about septic tank regulations, compliance checks and sewage treatment upgrades.

The general binding rules set out how septic tanks and small sewage discharges must operate to reduce the risk of pollution.

If your septic tank discharges directly to surface water such as a stream, river or ditch, you may be required to upgrade to a sewage treatment plant.

Compliance depends on factors such as where the system discharges, its condition and how it is maintained.

We can assess your septic system and advise whether it meets current requirements, along with any changes that may be needed.

Not always. Some systems can remain in place if they meet current requirements and are correctly maintained.

However, if your septic tank discharges to surface water, an upgrade to a sewage treatment plant may be required. We can confirm the best route once we assess your setup.

Yes. Alton Facility Services can advise on suitable sewage treatment options based on your property, discharge type and compliance needs.
