Iyer today announced that the ministry will be launching a mass media campaign to promote the twin-pit toilet soon.
"A twin-pit toilet is economical, safe, easy to clean, eco-friendly, and is effectively a self-contained waste treatment plant that does not harm the ground water beneath the toilet." he said.
Speaking on the issue of solid and liquid waste, he stressed that there was a paradigm shift underway in the way the Swachh Bharat Mission looks at this issue.
"Mission is moving from seeing it as a Solid Liquid Waste Management issue to seeing it as Solid and Liquid Resource Management, because waste is a resource that can be tapped and converted to wealth and energy," he informed.
Speaking on the issue of drinking water in rural India, he noted that there have been a number of initiatives to reform the National Rural Drinking Water Programme.
He enumerated several steps to improve the speed and quality of implementation of the programme, especially targeting arsenic and fluoride-affected habitations.
Though all the state governments are making efforts to make their states open defecation free (ODF) , the states of Bihar, Jharkhand and Odisa are still lacking behind.
