Tracking and reviewing data monthly allow the facility manager and/or tenants ongoing opportunities to identify inefficiencies or anomalies in consumption and immediately address problems, such as leaks and failed valves, before larger issues or excess consumption occur. Projects in a campus environment must only report usage from within the project boundary.

Identifying all Water Sources and Water End-Uses

Project teams must identify all water end uses in the building and on the project site. Teams should continuously analyze water consumption from each source to identify potential leaks or operational issues. Common end uses include plumbing fixtures, cooling towers, laundry facilities, dishwashers, indoor and outdoor water features, irrigation, and other building and site processes.

For each end use, identify the water source. Potable water sources include public water supply, on-site wells, and on-site potable water treatment systems. Alternative water sources include gray water, rainwater, recycled water, and reclaimed water. When using alternative water sources, meter them separately from municipally supplied potable water.

Meters and Types of Meters

Install meters only for systems within the scope of work. The prerequisite does not require meters for future tenant utility services and/or submeters not installed within the new construction scope of work.

Specify permanent meter(s) that provide water consumption data in gallons or liters. A utilityowned meter that provides the required data meets the prerequisite requirements. Utility providers often read and bill total water consumption monthly.

Tracking and reporting Demonstrate that the key person(s) responsible for tracking and reporting water consumption data can access the utility-owned meter. If the location is not accessible, providing access to monthly utility bill(s) achieves the same goal. If projects cannot demonstrate access through direct, visual readings or monthly utility bills, teams must install additional meter(s) to meet the prerequisite.

Multiple sources of potable or alternative water in a project boundary Teams must identify whether the project boundary uses multiple sources of potable water or alternative water. A single meter per water source can meet the requirement if the design allows for the proper placement of the meter. Projects with campus-level irrigation metering must submit an engineering calculation that accurately reflects the water consumption of the project
