Here are the metrics we will use: 
Water Savings: Calculate the reduction in water use by comparing historical usage data before and after the project implementation. 
Rainwater Harvesting Yield: Monitor the volume of rainwater collected and utilized. This helps to assess the effectiveness of the new rainwater collection systems.
Reduction in External Water Sources: Measure the decrease in dependency on external water sources, demonstrating the project's impact on increasing water self-sufficiency.
