If you operate a septic tank or small sewage treatment plant in the UK, you might be able to discharge wastewater into the ground without needing a permit. However, you’ll need to comply with the General Binding Rules. This guide will help you understand these rules and how to stay compliant.

Important Note: Different rules may apply for discharges into surface water. See separate guidance for those situations.

Essential Permissions

Even if the General Binding Rules apply to you, you may still need:

  • Appropriate building regulations approval
  • Planning permission, if required

Understanding Which Rules Apply

The specific rules you need to follow depend on when your discharge began:

Discharges Started Before 1st January 2015

If your discharge meets all the following, you only need to adhere to the rules that apply to all discharges:

  • Discharge existed before 1st January 2015.
  • You haven’t switched from surface water to ground discharge.
  • The discharge location hasn’t moved or has only moved within a 10-meter radius.
  • The discharge volume isn’t more than 2 cubic meters (2,000 litres) per day.

Discharges Started Between 1st January 2015 and 2nd October 2023

You must follow both the rules that apply to all discharges and additional rules if your discharge started on or after 1st January 2015 and before 2nd October 2023 or if you:

  • Switched from surface water discharge to ground,
  • Moved the discharge location by more than 10 meters,
  • Increased the discharge volume to over 2 cubic meters (2,000 liters) per day.

New Discharges Started On or After 2nd October 2023

If your discharge began on or after 2nd October 2023, or you meet any of the criteria mentioned in the previous category, you must follow all three sets of rules: those for all, for those starting between 2015 and 2023, and additional rules for new discharges.

Rules for All Discharges

  1. Discharge Limit: 2 cubic meters or less per day. Use the daily discharge calculator for residential sewage and British Water’s Flows and Loads guidance for commercial properties.
  2. Domestic Sewage Only: Ensure the sewage is only from domestic sources (e.g., toilets, bathrooms, kitchens) in homes or businesses like pubs and offices.
  3. Prevent Pollution: Don’t cause surface or groundwater pollution.
  4. Approved Systems: Use a septic tank or small sewage treatment plant with a drainage field for discharge.
  5. British Standard Compliance: Ensure your equipment meets the relevant British Standard in force at the time of installation (BS EN 12566 & BS 6297:2007).
  6. Maintenance: Maintain your system per the manufacturer’s instructions.
  7. Desludging: Regularly empty sludge.

Additional Rules (Discharges started between 2015-2023)

  1. Groundwater Protection: Your discharge cannot be in a groundwater source protection zone 1 (SPZ1). Check with Magic Map or the Environment Agency.
