Indian Railways’ renewed focus on drinking-water quality at stations is more than a maintenance exercise. It is a response to a basic infrastructure failure exposed by a Comptroller and Auditor General report: passengers and railway residents cannot reliably assume that water supplied through public systems is safe to drink.
The response now underway covers water sources, overhead reservoirs, pipelines, treatment plants, drinking-water booths and coolers. Eastern Railway, South Eastern Railway and Kolkata Metro have reported separate measures to test water, clean storage infrastructure and prevent contamination. Together, these actions show that the problem is not confined to an individual tap or station. It runs through the entire chain by which water is collected, treated, stored, distributed and monitored.
The CAG report, cited by Anandabazar, had identified poor drinking-water conditions at several prominent railway stations. It also recorded evidence of contamination in railway residential areas, including the presence of harmful coliform or E. coli bacteria. The report further highlighted the absence of dedicated drinking-water taps at many stations and inadequate regular testing even where such taps existed.
That combination is important. Water quality can deteriorate at more than one point between treatment and consumption. A water source may meet standards when tested, but the condition of storage tanks, pipelines, taps and dispensing equipment can affect what eventually reaches passengers. The railway response therefore includes both laboratory checks and physical maintenance, suggesting that authorities are treating the issue as a system problem rather than only a testing problem.
Eastern Railway’s intervention illustrates the scale of the monitoring exercise. Between September 13 and 19, it collected drinking-water samples from 132 sources to check for bacteria. It also collected 1,659 samples to examine residual chlorine levels after water treatment. Five additional chemical tests were conducted, according to the report.
Residual chlorine is a particularly significant operational indicator in a treated-water system. Chlorination is used to control microbial contamination, but the treatment process also has to be monitored so that the water supplied to users remains within acceptable limits. The reported sampling of residual chlorine indicates an attempt to track the effectiveness and consequences of treatment rather than relying only on occasional visual checks.
Before the inspection drive, Eastern Railway cleaned several overhead reservoirs and repaired defective or damaged pipelines. These measures address two physical parts of the distribution network that can affect water quality. Reservoirs are essential for maintaining supply across large railway complexes, while pipelines connect treatment and storage facilities to taps, booths and other points of use. If either component is poorly maintained, laboratory testing alone cannot provide a complete safeguard.
South Eastern Railway has reported cleaning nearly 14,000 water reservoirs. The figure includes facilities in railway residential areas, not only stations. This widens the public-health scope of the exercise. Railway colonies are also urban settlements, with residents dependent on the same institutional water infrastructure for daily use. Treating station water separately from residential water would leave a substantial part of the railway’s built environment outside the response.
The railway has also identified 167 locations where action is being taken to prevent contamination at the source. South Eastern Railway’s 63 water-treatment plants have undergone chlorine-related testing. At stations, authorities have placed greater emphasis on testing water supplied through drinking-water booths. The reported focus on points of use is important because passengers encounter the system through taps, booths and coolers, rather than through treatment plants or storage tanks.
Maintenance responsibility is another part of the problem. South Eastern Railway has entered into regular maintenance agreements with the agencies concerned for water coolers and booths at different stations. Such contracts can create a more defined operational responsibility for equipment that otherwise tends to fall between engineering, station management and external service arrangements. The report does not specify the contract terms or performance standards, but the move indicates that water quality depends not only on infrastructure installation but also on continuing upkeep.
Kolkata Metro has said that it is following regular testing to maintain drinking-water quality. The statement places metro stations within the same infrastructure conversation as the mainline railway network. Although metro systems operate in a different passenger environment, commuters still depend on publicly provided water points and expect the transport authority to maintain them safely.
The wider urban issue is the gap between visible infrastructure and functioning infrastructure. A drinking-water tap is a public amenity only when water is available, accessible and safe. A reservoir is useful only when it is cleaned and inspected. A treatment plant is effective only when its processes are monitored and its output is protected through distribution. The CAG findings, as reported, indicate that the presence of facilities did not always guarantee these conditions.
This distinction matters particularly at large railway stations. They bring together high passenger volumes, food vendors, long-distance travellers, railway staff and, in some cases, surrounding residential settlements. A failure in the water system can therefore affect different groups at the same time. Passengers may respond by buying bottled water, while railway residents may have fewer immediate alternatives for routine household use.
The report links the deterioration in tap-water quality at several stations to a growing preference among long-distance passengers for bottled water. That behavioural shift has a direct cost for passengers and also changes the role of public drinking-water infrastructure. When travellers stop trusting station taps, a publicly provided service is replaced by a commercial purchase. The available material does not quantify the additional cost to passengers or the volume of bottled water involved, but the reported change in behaviour is a clear indication of declining confidence.
The institutional response also shows how accountability is distributed across the railway system. Zonal railway administrations are responsible for local implementation, while ministry-level directions have prompted the current drive. Station water sources, treatment plants, reservoirs, pipelines, booths and coolers may involve different teams or agencies. Effective oversight therefore requires more than a one-time inspection. It requires records of testing, cleaning schedules, repair status, maintenance contracts and follow-up action at each location.
The available report does not establish how frequently every station will be tested, what standards will be applied uniformly across railway zones, or whether test results will be made public. It also does not say whether all deficiencies identified through the CAG process have been resolved. These gaps are important because a short inspection campaign can identify problems, but sustained water safety depends on routine monitoring after the campaign ends.
For passengers, the immediate significance is practical: the quality of water at a station depends on an interconnected chain rather than a single tap. For railway administrators, the challenge is to keep that chain functional across thousands of assets and multiple categories of users. For cities, railway stations are part of the public infrastructure network, and their water systems are a test of whether basic services are being managed as continuously operating utilities rather than as occasional amenities.
The evidence currently confirms a substantial corrective exercise. Eastern Railway has tested 132 water sources, examined 1,659 samples for residual chlorine and conducted five other chemical tests. South Eastern Railway has cleaned nearly 14,000 reservoirs, tested 63 treatment plants and identified 167 locations for contamination-prevention action. Kolkata Metro has reported regular testing. What remains to be established is whether these interventions produce consistent, transparent and lasting improvements at the points where passengers and railway residents actually collect water.
