CET

Smith Bros. & Webb designs and builds bespoke Contained Effluent Transfer Systems (CETs) that provide an essential service for train operators and for the comfort of rail passengers around the world.

The company provides a range of automatic and manual toilet emptying, rinsing and water filling, as well as a range of mobile bowsers.

Substantial ongoing savings can be made on water supply, detergent and effluent charges providing a fast return on capital outlay, as well as reducing pollution.

Smith Bros. & Webb is helping train companies to save time with the launch of its new ‘airline-style’ CET that works three times faster than conventional models. The fully automated CET uses negative pressure to evacuate 800 litres of effluent in just eight seconds - allowing a single operative to clean out tanks on a 12-carriage high speed train in just 10 minutes, a task that would have previously taken half an hour. The new Britannia CET uses technology similar to that used in airline toilets and is the first of its kind in the world, capable of emptying tanks on up to 30 trains a night.
