General Binding Rules FAQs

What updates were made to the General Binding Rules in 2020?

In 2015, General Binding Rules were updated to state that newly installed septic tanks must not discharge effluent into an open watercourse. Then, by 2020 it was required that all homeowners must replace their existing system if it drains into an open watercourse. You can read more detail on 2020 regulations here.

Although over 12 months has passed since this update to the General Binding Rules, we know that new legislation can still cause confusion and worry for homeowners. If you are concerned whether your drainage system is compliant with the latest regulations, contact our team.

How do I know my septic tank was installed to the correct British Standard?  

Your drainage system must meet the British Standard that is in place at the time of installation. The current standards in force for new systems are:

  • BS EN 12566 for septic tanks and small sewage treatment plants
  • BS 6297:2007 for drainage fields

If you wish to check on an existing system in place, look out for the following:

How do I know if my drainage is the correct capacity?

The company that installed your septic tank should have installed the correct size based on the size of your property and the number of inhabitants.

However, as a general rule, for a single house with up to and including 3 bedrooms your sewage treatment plant should be designed for a minimum population (P) of 5 people. You can read more on the right size of sewage treatment plant for your property in our previous blog. Alternatively, if you are concerned whether your septic tank or sewage treatment plant is too large or too small for your property, contact our team and we will conduct a site visit and advise on the best possible solution.
