What type of management strategy is encouraged for outdoor water consumption?

The recommended management strategy for outdoor water consumption focuses on installing meters for all exterior water uses. This approach is important because measuring water usage allows building managers and stakeholders to track consumption patterns accurately, assess their efficiency, and identify opportunities for water conservation. By understanding how much water is being used outdoors, it becomes easier to implement strategies to reduce waste, such as adjusting irrigation schedules or modifying landscaping requirements based on actual needs.

While the other options can contribute to effective water management, they do not offer the same immediate clarity and actionable insight as metering. For instance, a rainwater harvesting plan is beneficial for utilizing an alternative water source but does not give a complete picture of overall water consumption. Annual landscaping maintenance and seasonal irrigation adjustments can help optimize water use but lack the direct measurement necessary for effective strategy evaluation. Meters provide critical data that can inform all aspects of a water management plan.
