The SBM was launched with two variants — rural, to be implemented by the drinking water and sanitation ministry (now Jal Shakti), and urban, to be implemented by the housing and urban affairs ministry. One hundred million toilets have been constructed under the former in the past years; another 6 million have been built under the latter. The Centre has spent more than Rs 50,000 crore; the states together have spent a little less. From 12.6 million toilets constructed in 2015-16, the rate peaked in 2017-18, when more than 30 million toilets were constructed.
The central government gradually increased funds to the scheme. It also levied a new cess, above the service tax (before the goods and services tax was introduced), and collected nearly Rs 20,000 crore from it — 40 per cent of the overall funds spent by the Centre.
