Do Indians have safe drinking water?

What does ‘basic drinking water service’ mean?

The World Bank’s indicator ‘People using at least basic drinking water services’ follows the definition used by the WHO/UNICEF Joint Monitoring Programme (JMP) for Water Supply, Sanitation and Hygiene. According to JMP classifications, a ‘basic’ service means water from an improved source (such as a piped supply, borehole, protected well, or rainwater collection) provided that the collection time is not more than 30 minutes for a round trip. Importantly, the source must be located on the premises or be easily accessible. This indicator does not measure whether the water is free from faecal or chemical contamination. ‘Safety’ in the strict sense requires a separate indicator: ‘safely managed’ drinking water, which adds requirements for water quality testing and freedom from contamination. The data available for India only covers ‘basic’ services, not ‘safely managed’.

The trend: steady improvement since 2000

The World Bank’s estimates show a clear upward trajectory. In 2000, 79.49% of Indians had access to at least basic drinking water services. By 2024, that share had risen to 95.72%, an increase of more than 16 percentage points over 24 years. This means that approximately 96 out of every 100 Indians now have a water source that meets the basic criteria. The rate of improvement has been fairly consistent; the compound annual growth rate (CAGR) over this period is roughly 0.7 percentage points per year. Such progress is often attributed to large-scale government programmes such as the Jal Jeevan Mission (launched in 2019) and earlier schemes like the National Rural Drinking Water Programme, but the data itself does not attribute causality.

What the data does not say

First, the indicator does not capture water quality. Even an improved source can be contaminated. For example, microbiological contamination (E. coli, cholera) or chemical contaminants (arsenic, fluoride, nitrate) may still be present. The JMP’s ‘safely managed’ category requires that water be free from such contamination, but India does not yet report a national estimate for that indicator in this dataset. Second, the national average masks regional disparities. States with difficult terrain, poor groundwater quality, or weak infrastructure may lag behind. The data is only at the national level; no state-level breakdowns are provided in the evidence packet. Third, the indicator measures access via the primary water source used by the household. Households may still rely on multiple sources, and the one used for drinking may not always be the ‘main’ source. Fourth, the data is modelled by the World Bank and the WHO/UNICEF JMP, combining surveys, censuses, and administrative data. While it is the best available estimate, it is not a direct count.

Why the distinction between ‘basic’ and ‘safe’ matters

The question ‘Do Indians have safe drinking water?’ is increasingly relevant as the country faces water quality challenges. According to the Indian Ministry of Jal Shakti, several districts have groundwater contaminated with arsenic and fluoride above permissible limits. However, these figures are not part of the provided evidence. Without a direct measure of water safety, we cannot claim that the 95.7% figure represents ‘safe’ water. The JMP’s global database does include a ‘safely managed’ indicator for some countries, but for India the latest available value (2015–2020) is not included in this dataset. Therefore, the answer to the question must be cautious: a very large majority of Indians have access to a basic water service, but whether that water is safe to drink cannot be determined from this single indicator alone.

How does India compare to its neighbours?

The evidence packet does not contain comparative data for other countries. However, it is known anecdotally that India’s 95.7% basic access rate is similar to the South Asian average, but constrained by the evidence for this analysis.

Caveats and data quality

The source for these figures is the World Bank’s World Development Indicators (indicator code SH.H2O.BASW.ZS). The data is from the WHO/UNICEF JMP. The observations span 2000 to 2024 (66 annual observations). The earliest value (2000) and latest value (2024) are provided as locked numbers. These numbers are point estimates and may have confidence intervals, which are not given. The data is modelled using household surveys and censuses, with adjustments for consistency over time. Users should note that the COVID-19 pandemic may have affected survey data collection in some years, but the JMP methodology accounts for such gaps.

Summary

• 95.7% of Indians used at least basic drinking water services in 2024.
• This is up from 79.5% in 2000.
• ‘Basic’ means an improved source with a collection time of no more than 30 minutes. It does not guarantee the water is safe for drinking.
• The data is a national average; subnational variation is not provided in the evidence.
• No data on ‘safely managed’ (contamination-free) water is available in the packet.

Therefore, the most accurate answer to ‘Do Indians have safe drinking water?’ is: The data shows that almost all Indians have access to basic drinking water services, but safety is not directly measured. Additional water quality indicators would be needed to answer the question fully.
