EN 16922:2017/prA1

Railway applications - Ground based services - Vehicle waste water discharge equipment

This European Standard specifies the interface requirements for controlled emission toilet equipment on railway vehicles and the infrastructure, including catering area sink waste retention tanks. Vehicle and infrastructure specific requirements are also given.
The European Standard includes fixed and portable infrastructure equipment used to empty retention tanks, but excludes equipment fitted to railway vehicles where no fixed connections are used between vehicle and infrastructure.

Overview

EN 16922:2017/prA1 is a European Standard developed by CEN for railway applications, specifically focused on ground-based services and the requirements for vehicle waste water discharge equipment. The standard defines interface requirements between controlled emission toilet equipment on railway vehicles and supporting infrastructure, including catering area sink waste retention tanks. It outlines both vehicle and infrastructure-specific provisions, aiming to promote consistent, safe, and hygienic waste management for railway operators and infrastructure managers across Europe.

Key Topics

• Interface Requirements: The standard details how railway vehicle retention tanks for toilet and catering area wastewater must connect to ground-based discharge equipment, ensuring compatibility between vehicles and fixed or portable infrastructure.
• Retention Tanks: It specifies usability assumptions for various train types (e.g., number of uses per day for commuter trains; usage rate per seat/hour for intercity trains).
• Types of Equipment: Inclusion of both fixed and portable discharge solutions for emptying onboard waste water tanks, providing a broad solution base for different railway operational environments.
• Exclusions: The standard does not cover equipment fitted to railway vehicles where no fixed connections are established between vehicles and the infrastructure.
• Health and Environmental Considerations: Emphasis on controlled emission systems supports hygiene, environmental protection, and compliance with European regulations.

Applications

EN 16922:2017/prA1 is essential for several stakeholders in the rail industry:

• Infrastructure Managers: Provides clear requirements for the design and installation of ground-based waste water discharge stations at depots and maintenance facilities, ensuring safe and efficient emptying of retention tanks.
• Rolling Stock Manufacturers and Operators: Guides vehicle design specifications, particularly for the integration of controlled emission toilet systems and retention tanks. Ensures that onboard solutions can be reliably serviced by standard discharge equipment.
• Maintenance and Service Providers: Outlines procedures and equipment compatibility for routine servicing of railway vehicles, minimizing risk of spillage or contamination.
• Compliance and Regulatory Authorities: Assists in verifying that railway systems adhere to hygiene, environmental standards, and interoperability throughout the EU.

Related Standards

For comprehensive waste water management and railway application compliance, consider the following related standards:

• EN 16587: Railway applications - On-board equipment for treated waste water retention.
• EN 16185-1 and EN 16185-2: Specify requirements for railway vehicle cleaning and waste handling.
• UIC Leaflet 563: International Union of Railways guidance on toilet discharge equipment compatibility.
• EU Directives on Environmental Protection: EN 16922:2017/prA1 supports compliance with established EU waste water and pollution control directives.

Conclusion

EN 16922:2017/prA1 delivers unified and practical standards for vehicle waste water discharge equipment in the railway sector. Its focus on compatibility, safety, and environmental responsibility is vital for modern railway operations, especially as passenger hygiene expectations and sustainability regulations increase. Adoption of this standard helps ensure reliable, safe, and environmentally responsible management of waste water from rail vehicles across national and international networks.
