New Delhi: Uttar Pradesh and Delhi governments have said that they will remove all debris and solid waste from the Yamuna river bed by May 31. All the land-owning agencies which have a stake in the riverbanks will have to ensure that the work is completed and no further dumping is permitted. In case alternative land is not available for dumping of the debris, the waste should be sent to Burari except for horticultural waste, which will be used for composting.
