Pune’s water rights dispute is not only about a shortfall in annual allocation. It exposes a deeper problem in how the city’s population, newly merged villages, leakage, reuse claims and actual water consumption are being converted into an official entitlement.
The Pune Municipal Corporation has objected to the Water Resources Department’s decision to fix the city’s annual non-irrigation water entitlement at 11.33 TMC for the 2026-27 water year, despite the civic body seeking 21.34 TMC. The corporation has asked the department to reconsider the calculation on three grounds: the exclusion of the quota for 34 merged villages, the method used to calculate leakage, and deductions based on alternative water sources that it says are not available in practice.
The dispute matters because the competing figures describe two very different versions of Pune’s water system. The Water Resources Department’s calculation produces an entitlement of 11.33 TMC. The civic body, however, says its actual water use in 2025-26 was around 22.05 TMC. The gap between the two figures is not a minor accounting difference. It raises questions about whether the city’s formal allocation reflects the population and urban area it is already required to serve.
The corporation’s demand of 21.34 TMC for 2026-27 includes domestic and commercial consumption as well as water lost before it reaches residents. The city’s current reservoir reservations are reported as 11.50 TMC from the Khadakwasla project, 0.34 TMC from Pavana Dam and 2.67 TMC from Bhama Askhed, adding up to 14.61 TMC. The corporation argues that even this total does not reflect the separate 1.75 TMC quota approved for the 34 villages that were brought into the municipal limits.
The 34-village issue is therefore central to the dispute. According to the corporation’s objection, the total reservation including these villages should be 16.36 TMC, but the calculation used only 14.61 TMC. In practical terms, the civic body says 1.75 TMC has been approved for the merged villages but has not been included in Pune’s overall recognised reservation. That raises an institutional question: when an expanding city absorbs new settlements, does the water allocation system update the entitlement at the same pace as the administrative boundary?
The issue is not simply about adding villages to a table. Merged areas become part of the municipal service responsibility, but their inclusion also increases the demand placed on distribution networks, treatment capacity and source reservations. The report does not provide a separate population figure for the 34 villages, nor does it state how their demand was calculated. It does, however, establish that the corporation believes their approved quota has not been carried into the city’s overall water calculation.
### The leakage calculation
The second disagreement concerns the point at which leakage is measured. The Water Resources Department reportedly calculated a net water requirement of 14.750 TMC and added 13 per cent for leakage, producing a provision of 1.918 TMC. The corporation says leakage should instead be calculated on the total quantity of water that must be lifted and supplied to ensure that the required volume reaches citizens.
Using that method, the corporation calculates leakage at 2.204 TMC. It says the existing calculation therefore understates the requirement by 0.286 TMC. This difference illustrates why water entitlement is not equivalent to household consumption alone. A city has to draw, treat, convey and distribute more water than the amount finally consumed because losses occur within the system.
The supplied report does not establish whether the disputed 13 per cent reflects a measured network loss, an administrative assumption or a target. That distinction is important. If the percentage is based on actual performance, it describes the present condition of the distribution system. If it is a planning assumption, it determines how much water the city is formally allowed to draw. The corporation’s objection indicates that the two sides are not using the same base for the calculation.
This is a recurring administrative difficulty in urban water planning: demand is often recorded at several points in the system, while responsibility for source allocation and distribution is divided between different institutions. The municipality manages the service delivered to residents, while the water resources authorities determine source reservations and entitlements. A disagreement over the calculation method can therefore become a disagreement over institutional responsibility.
### The disputed alternative supply deduction
The third issue involves a deduction of 4.857 TMC. The Water Resources Department reportedly calculated a total requirement of 16.192 TMC and deducted this quantity for reuse, wells, borewells and rainwater harvesting. The deduction represents roughly 30 per cent of the requirement in the department’s calculation.
The corporation has objected to this deduction, saying that no water is currently available to it through reuse. It has also stated that around 3 to 4 TMC of treated water is supplied annually from the Mundhwa Jackwell for irrigation at the request of the irrigation department. In the corporation’s account, the city is not receiving reused water as an additional source for its own supply; instead, treated water is being made available for another stated use.
That distinction is significant because a source can exist within the wider urban water system without being available for municipal drinking-water supply. The report does not provide details on the treatment facilities, the quality category of the water, or the infrastructure required to redirect it to households. It does show that the corporation considers the 4.857 TMC deduction to be based on water that is not actually available to meet the city’s stated requirement.
The corporation has also pointed out that such a deduction was not included in an earlier water-entitlement approval. It has asked the department to reconsider both the basis of the current deduction and the actual availability of alternative sources. The disagreement therefore concerns not only the volume of water but also whether projected sources should be treated as equivalent to operational supply.
### What the numbers reveal
The figures in the report show a city operating with a large gap between formal entitlement and reported use. Pune’s actual water use in 2025-26 was around 22.05 TMC, according to the corporation. Against that, the Water Resources Department has fixed an annual non-irrigation entitlement of 11.33 TMC. The corporation’s requested 21.34 TMC is slightly below the reported previous-year use, but it includes domestic demand, commercial demand and leakage for the coming water year.
The figures also show how different accounting choices change the final allocation. Including the 1.75 TMC quota for the 34 merged villages would raise the reservation considered in the calculation from 14.61 TMC to 16.36 TMC. Recalculating leakage would add another 0.286 TMC according to the corporation. Removing or revisiting the 4.857 TMC deduction would further alter the calculation, although the supplied report does not provide the final entitlement that would result from the corporation’s preferred method.
The corporation has also sought an additional 5 TMC reservation from Mulshi Dam, but that request remains pending. This indicates that the present dispute is part of a larger effort to secure more dependable source capacity for a growing municipal area. The report does not state when the additional reservation request was filed or what decision-making stage it has reached.
The 30 per cent assumption for reuse, borewells, wells and rainwater harvesting also places several different kinds of supply under one heading. Some are potentially seasonal, some depend on local groundwater conditions and some require treatment or distribution infrastructure. The report does not provide separate quantities for each source, so it is not possible from the available evidence to determine how much of the 4.857 TMC is expected from reuse, groundwater or rainwater harvesting individually.
### The governance question behind Pune’s water rights
The dispute shows that Pune’s water planning is being shaped by at least four separate questions: how much water the city needs, how much water is reserved at the source, how much is lost in the network and how much water from alternative sources can be counted as available. These questions are connected, but they are not interchangeable.
A municipal corporation may seek an entitlement based on the water it must lift and distribute, while a source authority may calculate an entitlement after deducting quantities expected from reuse or local sources. If the assumptions are not jointly verified, the official number can be lower than the quantity the municipality says it already uses. The result is a planning system in which the city’s operational reality and its formal water right do not align.
The 34 merged villages add a further layer. Administrative expansion changes the service area immediately, but source allocation may follow a separate process. Unless the two are synchronised, newly included settlements can remain part of the city for governance purposes while their water requirement is treated separately or omitted from the headline allocation.
For residents, the immediate significance is that the final water entitlement will influence how the city approaches supply planning, source reservations and distribution management. The report does not announce a cut in supply or a new restriction. It records a formal objection and a request for reconsideration. The unresolved issue is whether the Water Resources Department will accept the corporation’s objections and revise the entitlement.
The next step rests with the Water Resources Department, which will have to respond to the corporation’s arguments on the merged villages, leakage calculation, alternative-source deductions and the pending Mulshi reservation. Until that decision is taken, Pune’s recognised water right remains substantially below the requirement and actual use figures cited by the civic body.
