There are four years left for the government target of ensuring all Indians use toilets, but in urban India alone, no more than 30 percent of sewage generated by 377 million people flows through treatment plants.
The rest is randomly dumped in rivers, seas, lakes and wells, polluting three-fourths of the country’s water bodies, according to an IndiaSpend analysis of various data sources.
An estimated 62,000 million litres per day (MLD) of sewage is generated in urban areas, while the treatment capacity across India is only 23,277 MLD, or 37 percent of sewage generated, according to data released by the government in December 2015.
Further parsing of this data reveals that of 816 municipal sewage treatment plants (STPs) listed across India, 522 work. So, of 62,000 MLD, the listed capacity is 23,277 MLD but no more than 18,883 MLD of sewage is actually treated.
That means 70 percent of sewage generated in urban India is not treated.
While 79 STPs don’t work, 145 are under construction and 70 are proposed, according to the Central Pollution Control Board’s Inventorization Of Sewage Treatment Plants report.
No improvement over the years; towns, cities pollute their own water
India’s towns and cities contaminate their own water, with no improvement over the years.
Sewage generation in India from class-I cities (with a population more than 100,000) and class-II towns (population 50,000-100,000) is estimated at 38,255 MLD, of which only 11,787 MLD (30 percent) is treated, according to the Faecal Sludge Management (FSM) report by Water Aid, a safe-water and sanitation advocacy, quoting a 2009 CPCB report.
The untreated sewage is dumped directly into water bodies, polluting three-fourth of India’s surface water resources, the FSM report said. Up to 80 percent of water bodies could be polluted, the report said.
Operation and maintenance of existing treatment capacity is below par, with 39 percent plants not conforming to environmental rules for discharge into streams, the CPCB report said.
An estimated 75 percent to 80 percent of water pollution is from domestic sewage, discharged untreated into local water bodies.
A general, growing shortage of (working) sewage-treatment plants
Of the 522 working STPs across India, the maximum are in the northern state of Punjab, which has 86. But no more than 38 work.
Uttar Pradesh has the most working STPs, 62, followed by Maharashtra (60) and Karnataka (44).
About 85 million in urban India lack adequate sanitation - more than Germany’s population
About 17 million urban households lack adequate sanitation facilities in India, with 14.7 million households without toilets, the FSM report said.
If you consider five people per family, that means about 85 million people - or more than the population of Germany - are without adequate sanitation in urban India.
In terms of rural households, only 48.4 percent (87.9 million) have toilet facilities as on December 7, 2015, according to a reply in the Lok Sabha.
Around five million (7.1%) urban households having pit latrines that have no slabs or are open pits, and about 900,000 toilets dispose off faeces directly into drains.
Only 32.7 percent of urban households that have sanitation facilities use toilets connected to an underground sewage network.
As many as 30 million urban households (38.2 percent), of the 79 million households with septic tanks, have no clear method for sewage disposal.
Open defecation remains a major challenge
About 12.6 percent of urban households defecate in the open. This number is higher for slums, with 18.9 perceent of households defecating in the open.
Around 1.7 percent of households across India defecate in the open despite having toilets, the government informed the Lok Sabha in a reply last month, based on a 2012 National Sample Survey report.
In Madhya Pradesh, around 22.5 percent urban households defecate in open spaces, followed by Tamil Nadu (16.2 percent), Uttar Pradesh (14.8 percent), Gujarat (8.7 percent), Maharashtra (7.7 percent) and Delhi (3 percent).
A staggering 55 percent of rural households defecate in the open, according to data tabled in the Lok Sabha on May 7, 2015. Odisha tops list, with 86.6 percent of rural households defecating in the open. In Kerala, no more than 3.9 percent of households defecate in the open.
The global story: Open defecation has fallen by half over 25 years
The proportion of people practising open defecation globally has fallen almost by half, from 24 percent in 1990 to 13 percent in 2015.
About 68 percent of the world’s population had access to improved sanitation facilities, including flush toilets and covered latrines, in 2015, according to the World Health Organization (WHO).
However, nearly 2.4 billion people across the world lack basic sanitation facilities, such as toilets or latrines. Of these, 946 million defecate in the open, according to the WHO.
Will building toilets address the issue? The jury is out
The Swachh Bharat (Clean India) Mission, launched by the National Democratic Alliance government on October 2, 2014, aims to make India open-defecation-free by October 2, 2019.
The government plans to construct 2.5 million individual household toilets in urban areas by 2015-16, of which 882,905 were constructed upto December, 2015, according to latest data available.
As many as 32,014 out of 100,000 community and public toilets have been built under the Swachh Bharat Mission. The rural sanitation programme, in its first year, saw the construction of 8.8 million toilets, against the target of 6 million.
