In case of Foreign Railways discharge treatment is different. Have seen the treatment in case of China - Tibet rail line shown in Nat Geo. They said that all Coaches have a discharge box underneath and this is where the discharges are stored. Once the train halts at a major station (usually every 6-8 hrs or so) where halt is 10 mins, a special teams awaits. The discharge is pumped out from the carriage to the trucks waiting (by use of pipes). The trucks ten take it to the treatment plant / sewage plant etc. The entire pumping process takes 10 mins max as they ensure everything is ready when the train arrives.

have also given the reason stating that if it is discharged enroute they will have to incur additional costs as lyf of the rail track and sleepers decreases.

I have for a longtym felt that such discharge system should be used in Indian Railways also.
