A Memorandum of Understanding has been signed by Ministry with Defence Research and Development Organization (DRDO)for Joint Technology development using Defence Research & Development Establishment (DRDE) bio-digester technology for passenger coach toilet systems. Designs have been developed jointly by RESO & DRDO based on this technology and Indian Railways Production Units have been instructed to manufacture two rakes based on this technology. Zero Discharge Toilet System (ZDTS) has been developed jointly by Research Design & Standards Organization (RDSO) and Indian Institute of Technology (IIT), Kanpur. Efforts are also in hand to carry out trials of vacuum retention type toilets on Shatabdi Trains.

ZDTS has been tried out on one coach based on design jointly developed by RDSO, Lucknow and IIT, Kanpur. The action is in hand by RDSO to carry out extended trials o one rake based on this technology.

Suitable technology option for Indian Railways operating conditions are yet to be established for which Railway is working on various technology options as described above. Further course of action regarding adoption of suitable technology mix for all trains will be taken, based on the outcome of trials with different technology options.
