Trivandrum central railway station is one of the biggest customers of Kerala water au-thority. The water consumption of railway station is about 50 ML/ month. A major por-tion of the water consumed is utilized for washing trains and tracks. Therefore, about 0.8 MLD of waste water is produced as train and track wash water in the Trivandrum cen-tral railway station. This waste water is discharged into public sewage line without any treatment. If this waste water can be reclaimed it can be reused for washing trains, tracks and platforms.
In this study, the waste water samples at Trivandrum railway station were taken from three sources (Bio toilet effluent, fresh train wash water, sewage line waste water) and examined for the water quality parameters. The initial water quality parameters of the sample inferred that this waste water is treatable and reclaimable. For that a lab scale model of treatment unit was set up. After the treatment, the maximum BOD reduction was 94%, COD reduction 82.5%, Total solids reduction 98% and oil& grease reduction 99% was reported. The final effluent quality parameters satisfied KSPCB limits. The maximum quantity of waste water produced was found as 0.8 MLD from the data. By treating 8L of waste water in the lab scale model, a good quality effluent of 2.5L was obtained. By implementing a WWTP in the Trivandrum railway station 0.25 MLD of water can thus be reclaimed.
