Not only will the feasibility study to repair the existing Malabar Hill Reservoir without building a new tank play a role in the decision, but the cost will also be a determining factor for the civic body on whether or not to proceed with constructing a new tank. The issue of building a new tank has been unresolved for over a year.

The debate surrounding the reconstruction of the 144-year-old reservoirs and the addition of new ones has been ongoing for more than a year and a half. In February 2023, a work order was issued for the construction of an additional 90-million-litre capacity tank, along with the reconstruction of old reservoirs, at an estimated cost of R698 crore.
