"By the end of May, Uttarakhand will be open defecation-free, barring a few areas in Haridwar," Mr Rawat told PTI in an interview.
The 56-year-old chief minister said a plan is being chalked out to rejuvenate the two rivers in Dehradun -- Song and Tons -- so that clean water flows through them.
"The confluence of the two rivers is already free from smell. Birds have started drinking water there. It is an encouraging news," he said.
Mr Rawat assumed the charge of chief minister of Uttarakhand on March 18 after the BJP stormed to power winning 57 of the 70 assembly seats and ousted the Congress. He also highlighted the BJP government's transfer policy for state bureaucrats and police officers saying it was completely transparent and balanced.
"There has not been a single complaint regarding the transfers we have done. There was no corruption in the transfers, these were balanced and transparent," he said.
