Kolhapur Municipal Corporation (KMC) water and sewerage charges are structured based on a slab system and usage. The cost per kiloliter of water varies depending on the volume consumed, with higher usage generally resulting in a higher per-unit cost. For example, the first 8,000 liters might be charged at one rate, the next 17,000 at another, and so on, according to NoBroker. To calculate the total bill, one would multiply the consumption in each slab by the corresponding rate and then sum the amounts.
