Lucknow, Aug 3 (ANI): Workers of BJP launched a campaign to clean Gomti River in Uttar Pradesh on Sunday. BJP workers, who took up cleaning work of the river in Lucknow, said the campaign was on the lines of Prime Minister Narendra Modi's 'Clean River Ganges' project. Workers, who removed weeds from the riverbank, said river Gomti was a tributary of river Ganges only and it also required a clean up. Hindus bathe in the Ganges in an act of ritual purification, yet the 2,500 km (1,600 mile) river stretching from the Himalayas to the Bay of Bengal is full of industrial effluent and untreated sewage, its banks strewn with garbage.
