What Are the General Binding Rules?

3rd May 2024

The General Binding Rules serve as essential regulations governing the discharge of sewage in the United Kingdom. These rules play a crucial role in ensuring that sewage is managed and disposed of in an environmentally responsible manner. But what are they?

In this blog post, we will look at what the General Binding Rules are, understand their significance, compliance requirements, and the broader implications of following these regulations for sustainable sewage management in the UK.

So, what are the general binding rules?

The General Binding Rules are a set of regulations established by environmental authorities in the United Kingdom to govern the discharge of sewage from domestic properties or small businesses. These rules aim to ensure that sewage is managed effectively and does not pose a threat to the environment or public health.

The importance of the GBRs lies in their ability to set clear standards and requirements for the treatment and disposal of sewage. They help prevent pollution of water sources, protect ecosystems, and maintain the overall cleanliness of the surroundings. Compliance with these rules is vital to mitigate the negative impact of sewage discharge on natural habitats and human well-being.


The Rules

The General Binding Rules in the UK regulate small sewage discharges and are crucial for those who discharge waste water to specific locations such as surface waters like rivers and streams. These rules ensure proper treatment and management of sewage to protect the environment. 

Here are some key points regarding the General Binding Rules:

  1. Rule Compliance: It's essential to comply with the specific rules outlined in the publication "Small sewage discharges in England: the general binding rules." You can find all the sections to the rules via the link and we encourage you to read through and understand them.

  2. 2020 Regulations: Under the 2020 General Binding Rules, septic tanks that discharge directly to surface water must adhere to government legislation to ensure compliance.

  3. Replacement Requirement: Septic tanks that discharge to ditches, streams, or rivers must be replaced to meet the General Binding Rules for small sewage discharges.

  4. Permit Exemptions: Under these rules, small sewage discharges can be made without a permit to certain types of "receptors," such as fresh surface waters.

  5. Volume Restrictions: The discharge volume should not exceed 2 cubic metres per day as per if it discharges directly to the ground.

  6. Recent Updates: The Environment Agency has introduced new rules, numbers 22 and 23, impacting users of private drainage systems, emphasising the dynamic nature of these regulations.

Purpose of the GBRs:

The primary purpose of the GBRs is to regulate the treatment and disposal of domestic sewage in a way that minimises pollution and protects natural ecosystems. By setting standards for the operation of septic tanks and small sewage treatment plants, the GBRs seek to maintain water quality, prevent contamination of surface water and groundwater, and reduce the risk of diseases associated with inadequate sewage management.

The Key Components of the GBRs:

  1. Treatment Requirement: Property owners must use an approved septic tank or sewage treatment plant to treat sewage before discharging it into the environment.

  2. Compliance Standards: The GBRs stipulate compliance standards that septic tanks and sewage treatment plants must meet, such as British Standards like BS EN 12566-1 certification.

  3. Discharge Limits: There are specific limits on the volume of sewage that can be discharged per day to prevent overload and ensure proper treatment.

  4. Environmental Protection: The GBRs emphasises the protection of surface water and groundwater from pollution caused by untreated sewage discharge.

Understanding these key components is essential for property owners to ensure they comply with the GBRs and contribute to responsible sewage management practices in the UK. Compliance with these rules is critical for maintaining a clean and sustainable environment for current and future generations.

Compliance Requirements

To comply with the General Binding Rules (GBRs) in the United Kingdom, you must adhere to specific standards for septic tanks and sewage treatment plants. Understanding these compliance requirements is crucial for ensuring proper sewage management and environmental protection.

Compliance Standards:

Septic Tanks:

  • Property owners must ensure that their septic tanks meet the British Standard BS EN 12566-1 or equivalent certification.

  • Regular maintenance and inspection of septic tanks are necessary to uphold compliance standards and prevent issues like leakage or overflow.

Sewage Treatment Plants:

  • Sewage treatment plants must meet the relevant British Standards for performance and efficiency. When it comes to sewage treatment plants, meeting the relevant British Standards for performance and efficiency is crucial. Compliance with these standards plays a vital role in ensuring that sewage undergoes adequate treatment before being discharged into the environment. 

  • BS EN 12255 for wastewater treatment plants, encompassing general construction principles.

  • BS EN 12566 for septic tanks and small sewage treatment plants.

  • BS 6297:2007 for drainage fields.

Treatment Requirements:

  1. Treatment Process:

    • A septic tank system and sewage treatment plants must effectively treat sewage to remove harmful pathogens and pollutants.

    • Treatment processes may include mechanical, biological, and chemical methods to ensure the quality of the discharged effluent.

  2. Discharge Limits:

    • The GBRs impose limits on the volume of sewage that can be discharged per day from septic tanks or sewage treatment plants.

    • Adhering to these discharge limits helps prevent overload, reduces the risk of pollution, and safeguards water quality in surrounding ecosystems.

Importance of Compliance:

  • Fulfilling compliance requirements for septic tanks and sewage treatment plants is essential for protecting the environment, public health, and ensuring sustainable sewage management practices.

  • Non-compliance with the GBRs can result in fines, legal implications, and environmental harm, highlighting the significance of meeting these regulatory standards.

By understanding and meeting the compliance requirements outlined for septic tanks and sewage treatment plants, property owners can contribute to a cleaner and healthier environment while adhering to the guidelines set forth by the General Binding Rules in the UK.

Recent Changes and Updates:

2020 Amendments:

  • In 2020, significant amendments were made to the GBRs concerning the discharge of sewage from septic tanks and small sewage treatment plants.

  • These updates emphasised stricter standards for sewage treatment and aim to enhance environmental protection measures.

Surface Water Discharge:

  • One notable change includes restrictions on the direct discharge of sewage into surface water bodies, requiring alternative disposal methods to comply with current legislation. Under these rules, septic tanks that discharge directly to surface water no longer comply with government legislation.
    This change mandates that alternative disposal methods be implemented to adhere to the updated regulations. By prohibiting direct discharge from septic tanks into surface water, the rules aim to enhance environmental protection and promote sustainable sewage management practices.

  • Property owners must adhere to these updated guidelines to meet the revised regulations effectively.
