The General Binding Rules, which affect septic tank owners, are tightening in 2020 and placing greater restrictions on septic tanks discharging into a watercourse.

Discharges from septic tanks directly to surface water are not allowed under the General Binding Rules. Under the new rules, if you have a septic tank that discharges directly to a surface water pipe, ditch, stream or river, you will need to replace or upgrade your treatment system by 1 January 2020, or when you sell your property, if before this date.

If the Environment Agency finds evidence that your septic tank discharging currently is causing pollution, you will need to replace or upgrade your system before 1 January 2020.

How can I make sure my septic tank is compliant?

If your septic tank is not compliant, you can take the following steps, in order to meet the new requirements

  • Connect to a mains sewer – where available
  • Install a drainage field (also known as an infiltration system) so the septic tank can discharge to ground instead
  • Replace your septic tank with a small sewage treatment plant. A small sewage treatment plant (also known as a package treatment plant) uses mechanical parts to treat the liquid so it is clean enough to go into a river or stream
