The National Ganga River Basin Authority (NGRBA) has sanctioned a Rs 315.34 crore scheme to check pollution in river Ganga in Uttar Pradesh's Allahabad district.

"The NGRBA has sanctioned an ambitious scheme of Rs 315.34 crore to check pollution in river Ganga in Allahabad,"  principal secretary urban development Alok Ranjan said here on Wednesday.

He said while 70% of the cost of the scheme will be borne by the Centre, the rest will be the state's contribution.

"Of the total amount, the Centre will release Rs 10 crore in the current fiscal as first instalment," he said.

The principal secretary said at present Allahabad city generates nearly 228 MLD sewerage, of which only 39 per cent is treated.

"Thus nearly 61% of the sewerage is being disposed of in the river," he said.
