BS EN 16922 is a European standard on railway vehicles that discusses wastewater discharge equipment.
BS EN 16922 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.
BS EN 16922 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.
BS EN 16922 on railway vehicle wastewater discharge is useful for:
Toilet systems are designed to operate on the principle of high - flush through which the evacuation of the toilet bowl is carried out by means of water pressure.
BS EN 16922 provides the description of vacuum and controlled emission toilet systems fitted to railway vehicles.
Identification of the toilet system and connections on the railway vehicle wastewater discharge equipment are mentioned in BS EN 16922.
BS EN 16922 provides the requirements for generic types of toilet waste retention systems.
Furthermore, BS EN 16922 could assist you in designing and manufacturing wastewater retention tanks to minimize the practice of spilling toilet waste onto railway station areas and in inhabited areas of the city, which provides a hygienic atmosphere and improves environmental conditions at railway stations.
