SOLAR POWERED STP

Transit and daytime centers are places where people either do business or rest for a while and their residence is elsewhere. Examples are rest rooms in bus stations, railway stations, airports, seaports, factories operating only in dayshifts, educational institutions, day time offices etc. In these places, almost every person will use the urinal but not the water closet-understandably. As such, the composition of the sewage from such places has a serious imbalance between the night soil and urine proportions which in turn impact the BOD and ammonia respectively as compared to domestic sewage. The issue in managing such a “pseudo-sewage” and efficiently reusing the water can be solved with the help of Solar Powered Sewage Treatment Plant (SP-STP) developed jointly by IIT Madras & Greenvironment India
