The Role of Controlled Emission Toilets in Modern Rail

Since 1988, Controlled Emission Toilets have been standard on UK rolling stock, transforming onboard hygiene and environmental management. These sealed systems safely collect and contain waste until it can be discharged at depot facilities. By preventing direct discharge onto the tracks, CET systems contribute to a cleaner, safer, and more sustainable rail network.

Servac’s expertise in CET servicing and maintenance ensures your fleet remains compliant, hygienic, and efficient.

Enhancing Passenger Experience Through Reliability

Toilet reliability directly influences passenger satisfaction. A malfunctioning system can lead to carriage withdrawal, costly delays, and reputational damage. Servac’s preventative maintenance programmes are designed to reduce breakdowns and extend component life — delivering cost-effective reliability.

Our trained technicians perform detailed inspections, cleaning, and repairs to ensure every vacuum toilet system continues to meet operational and hygiene standards.

Advanced Testing and Diagnostic Facilities

Our West Sussex facility houses advanced diagnostic equipment for CET tank and vacuum toilet testing. Each unit undergoes precision inspection, pressure and flow testing, and performance verification. We use specialist tools to identify faults quickly, carry out repairs, and confirm reliability before dispatch.

This investment in technology allows Servac to deliver fast turnaround times and consistent results for every customer.

Dependable Maintenance and Long-Term Support

Servac’s commitment to quality extends beyond repairs. We provide comprehensive support packages covering routine servicing, CET tank refurbishment, and vacuum toilet upgrades. Whether you require emergency response, component replacement, or scheduled maintenance, our team ensures system reliability for years to come.

With Servac, you gain a dependable partner for rail toilet maintenance, helping you achieve maximum uptime, cleaner facilities, and greater passenger confidence — journey after journey.
