The report, which is part of a three year (2014-17) collaborating programme undertaken by TERI, Coca-Cola India and USAID, said the government should come out with a tangible business plan to rope in the corporates in the campaign.
The government's approach is now first to create facilities like toilets, "because unless toilets are built we cannot move forward," Arun Kansal, Head of Coca-Cola Department of Regional Water Studies said.
"Swachh Bharta Mission will be able to achieve target as far as access to sanitation is concerned, but for most decentralised toilets we are depending on the soak pit and septic tanks to transfer surface pollution to sub-surface level. That is something which is still a grey area," he said.
The report has recommended that the government also improve data management, monitoring and review situation.

Apart from the need for holistic approach encompassing faecal sludge management, water supply needs to be integrated with the Swachh Bharat Mission.
The TERI report has pointed out that along with construction of toilets, the government needs to revise the water supply to urban and rural areas to make the toilets usable.
It has suggested that the goal of the Swachh Bharat Mission can be achieved if the current incentive, in the form of a subsidy that covers 30-50 per cent of the cost of building a toilet, is leveraged to raise additional funds through market-based resources by facilitating innovative financing options.
"There is no clear-cut road-map for how the government visualise the role and participation of the corporates. There is no clear-cut policy framework where in corporates are able to see their role," Kansal commented.
