Definition of Water Supply Project expands tariff exemption scope by clarifying included facilities and treatment processes. The notification substitutes the Explanation for 'Water Supply Projects' to define a Water Supply Project as including a water pumping station, water storage facility (reservoir) and a water treatment plant performing desalination, demineralization, purification or similar processes intended to make water fit for agricultural or industrial use, thereby clarifying which components and processes qualify under the tariff provision.
