As the dependency of buses increase in this part of TN, more buses will be introduced and they will be cleaner also. The introduction of mechanised bus clean facility in Trichy will reduce the time to clean the buses from 30 min to 3 min. The impure water will be sent out as the brushes move from one part to another.
I am not sure how this helps the water conservation. Usually in this mechanised washing facilities, there will be a water recycling unit which will recycle the water for cleaning. But there is no mention of that anywhere. Does that mean, that we are wasting water and electricity to clean the buses. If it is , it will negate the benefits of labour savings and time savings.
We also know that barring new buses, all the other vehicles may not have sealed glass windows. If the windows are not sealed before washing, well, the passengers will have a wet ride.
