Correct Option (4)
This option recommends a charge based on the consumption of water, with differentiated charges for non-BPL and BPL families. This approach promotes responsible water usage and discourages wastage, as users pay according to their consumption. The differentiation in charges ensures that BPL families are not unduly burdened, aligning with principles of social equity while also allowing for partial cost recovery. It represents a balanced strategy that considers both economic viability and social welfare, encouraging efficient resource management.
Incorrect Options:
Option 1: Recommending that the supply of water be free of charge in all respects is financially unsustainable. Without any revenue, the long-term operation, maintenance, and potential expansion of the water supply project would be impossible, leading to its eventual failure. This approach also provides no incentive for efficient water use, potentially leading to wastage.
Option 2: Recommending a one-time fixed sum for the installation of taps, with free water usage, presents a significant barrier for BPL families who may not be able to afford the upfront installation cost. Furthermore, once the taps are installed, there is no mechanism to regulate or charge for water consumption, which could lead to inefficient use and strain on the water resource, undermining the project's sustainability.
Option 3: Recommending a fixed monthly charge only on non-BPL families, with free water for BPL families, is a viable approach that balances social equity with some cost recovery. It ensures access for the most vulnerable while generating revenue from those who can afford it. However, this option does not incentivize efficient water use among non-BPL families beyond the fixed charge, and it may not be as effective in promoting resource conservation as a consumption-based model. While administratively simpler than a metered system, it may not achieve optimal resource allocation or maximum cost recovery compared to a differentiated consumption-based charge.
