Controlled Emission Toilet Systems

Like CWM’s, Controlled Emission Toilets (CET’s) play an essential role in the performance of railways, with a huge amount of investment is being made to upgrade depots across the country that house and maintain the new and improved trains. As new rolling stock is introduced or older trains upgraded, there is a greater demand for CET systems, as the position of the holding tanks on the train will differ by train type and configuration. Another problem faced by operators is that many depots were designed and built many years ago without any thought of the provision of toilet emptying equipment. These potential obstacles have led to the creation of purpose-built maintenance equipment – in this case Temporary CET’s. For example, when running an eight car set to and fro and the capacity changes to a 12 car, there is a requirement to add more CET points. Similarly, alongside the emptying of effluent tanks is the necessity for the fuelling of on-board water tanks for the purpose of toilet flushing, hand washing and, occasionally, potable water.

The use of temporary CET’s when renewing or upgrading facilities to meet the changing needs of train operating companies has become a more popular solution for train operators for many reasons, including:

• Shorter Lead-times
• More cost effective
• Tailored solution
• More flexible option – Available for any Location
• Less impact on running of services
