Recent data shows that drinking water coverage has improved considerably in India with 89 percent of the rural population having access to an improved water source within a round trip of 30 minutes. Fifty percent of rural households have a tap connection within the dwelling or premises according to the Department of Drinking Water and Sanitation, Ministry of Jal Shakti, Government of India, as of 31 May 2022.
However, there is a very little information on whether the progress in creating physical infrastructure has translated into an improvement in the reliability and safety of drinking water services in rural households, argues this Council on Energy Environment and Water (CEEW) Issue Brief titled "How safe are drinking water services in rural India?' authored by Nitin Bassi, Karthik Ganesan, and Ashish Dangi.
To explore this further, the brief looks at the extent to which data on safely managed water is reported in India. It analyses four main national government sources that report data and information on rural drinking water services in India. These include the Census of India, National Sample Survey (NSS), National Family Health Survey (NFHS), and the Integrated Management Information System (IMIS) dashboard maintained by the Department of Drinking Water and Sanitation (DDWS), Ministry of Jal Shakti, Government of India.
The analysis finds that:
The
While the census has for the first time included the distinction between improved and unimproved sources, physical access data does not provide the distinction between the number of households having access to a water source within the dwelling unit and those within the household’s premises or compound. Information on the frequency, duration, and quantity (reliability aspect) of the water supply is also not available. Also, while distinction is made between treated and untreated tap water, the water quality information for other improved sources is missing.
Thus, the details provided by the Census of India are insufficient to make inferences concerning the different components of safely managed drinking water services as the data on the reliability of the service are missing and that on the quality of water supplied is only provided partially (i.e., only for tap water).
NSS 76th round collects information on the type of water sources, sufficiency of drinking water from the principal sources, type of household access to the principal source of drinking water, treatment and storage of drinking water by the household etc.
While the NSS data includes more detailed information on the type of sources, information on the sufficiency of drinking water sources, type of access, and the treatment and storage facility at the household level, the information provided is for the representative number of households. Also, the information needs to be more comprehensive with better definition of parameters.
The NFHS includes indicators on population, health, and nutrition for a representative sample of households. The 5th NFHS (2019-21) uses a key indicator for water supply, that includes, people living in households with an improved drinking-water source. The improved water sources considered by NFHS include piped water into dwelling/yard/plot, piped to the neighbour, public tap/standpipe, tube well or borehole, protected dug well, protected spring, rainwater, tanker truck, cart with small tank, bottled water, and community RO plant.
However, the findings are based on a representative sample of households and distinction between treated and untreated water supply is not made. NFHS includes population as a unit of analysis while the NSS and Census of India data use households as the unit of analysis making it difficult to compare data. Also, the data sets do not provide information on the household’s physical access to a water source.
The IMIS dashboard was created since the launch of the National Rural Drinking Water Programme (NRDWP) in 2009 by the DDWS. Till 2019, this dashboard provided information on the sources of water supply, households’ physical access to water supply, coverage of water supply (in terms of habitations covered), and water quality affected habitations.
The dashboard has undergone a change with the launch of the JJM (Jal Jeevan Mission) and now provides real-time information on households covered by a functional household tap connection, active laboratories for water quality testing, the number of drinking water samples tested by the laboratories, and those by using the field testing kits, and the number of water samples which were found to be contaminated along with earlier information.
However, there are limitations on the data available. Only a small proportion of villages are covered under the IoT for data on the average daily quantity of water supply, at present. There is lack on information on the frequency of water supply, and whether supplied water is treated or untreated. Information for the tested water samples, source of water sample collection and the type and extent of contamination also continues to be inadequate.
The analysis of data sets reveals that data from these different sources cannot be compared as data collection is undertaken with different mandates and frequencies. Indicators used to evaluate safety and access to drinking water are different for each kind of source. The units of data analysis are different. The indicators considered by various agencies to report progress in rural drinking water services are aligned only partially with those necessary to determine whether such services are safely managed.
The brief argues that the existing data sources and the information system appear to be inadequate, and it is difficult to derive any conclusions that can help policymakers and water managers make decisions and undertake any future actions. There is thus an urgent need to strengthen the existing data and information systems and validate progress made by:
