To earn credits from water use reduction, how must the water savings be achieved?

To earn credits for water use reduction, the savings must be achieved specifically by reducing the amount of metered water use. This approach focuses on minimizing the total water consumption in a facility through efficiency measures, behavioral changes, or infrastructure improvements rather than increasing fixture counts or installing more faucets. Achieving water savings through metered usage reduction demonstrates a clear management strategy that directly correlates to decreased operational costs and environmental impact.

This method aligns with sustainability goals by emphasizing the importance of efficiency and conservation rather than simply increasing the quantity of fixtures or alternative sources. The other options may contribute to water management but do not explicitly demonstrate a reduction of metered water usage, which is essential for earning credits in this context.
