At Indian railway stations, the income of water bottle sellers is dictated by the price regulations set by Indian Railways and IRCTC, which stipulate the maximum retail price and purchasing costs. Sellers typically make a profit of ₹2 to ₹3 on each bottle sold. While this margin may seem low, the volume of sales compensates for it, allowing these vendors to make a reasonable income despite smaller profits per unit.

The water bottle business at railway stations is a crucial aspect of the commuter experience, providing essential hydration for travelers. With trains often being crowded and long journeys common, the demand for convenient access to bottled water is consistently high. Thus, for sellers, the key to profitability lies not just in the margin per bottle but also in their ability to sell large quantities throughout the day, particularly during busy travel times.

Moreover, the regulations set by authorities not only affect the profits of these vendors but also ensure that customers have access to reasonably priced necessities during their travels. This creates a balance between the needs of the vendors to earn a livelihood and the necessity for travelers to obtain affordable refreshments on the go.
