Starting Friday, Union ministers, top bureaucrats from Centre and states will have the additional task of putting in a few hours of service (shramdaan) during the next fortnight for achieving complete cleanliness. The activities they can do is either dig or supervise construction of twin pit latrines or cleaning public places in their constituencies or native places to set an example. Government sources said the “Swachhta hi Sewa“ campaign will be the biggest ever campaign for any scheme and it will be launched by President Ram Nath Kovind from a village in Kanpur. He will also administer the Swachh Bharat pledge from there. “It will be an unprecedented campaign with events and shramdaan happening in every state, district, block, panchayat and village. There will be mass mobilisation. For fifteen days the country will talk, think and act about Swachhta,“ a source said. Prime Minister Narendra Modi has called a meeting of council of ministers on Tuesday where the Swachh Bharat issue will come up for discussion. Modi had mooted the idea of running this campaign from Sept 15 to Oct 2 when everyone contributes to the government&#039;s flagship programme.
