Confirm the number of make-up water systems within the project boundary, and meter each system individually. Provide infrastructure capable of reporting and recording hourly consumption.

A single meter that reports total make-up water to a building or site does not meet the credit requirements.

Commercial kitchens Typical commercial kitchen systems such as dishwashers, food steamers, and combination ovens require large quantities of potable water. Even when using water-efficient equipment, it is critical that projects track consumption from these appliances to ensure efficient operations and identify water supply failures.

The requirement for metering water use in a commercial kitchen depends on the number of daily meals served. Kitchens designed to serve 100 or more daily meals must meter and report all water use from the kitchen operations.

Public laundry facilities Typical commercial laundry systems include large top- or front-load washing machines used to process thousands of pounds (lbs) or kilograms (kg) of laundry annually. Front-load washers use less water and energy than top-load washers; however, even when using ENERGY STAR® (or performance equivalent) equipment, it is critical that projects track water consumption from these machines to ensure efficient operations and identify water supply failures.

The requirement for metering water use in a commercial laundry depends on the pounds (lbs) or kilograms (kg) of laundry processed annually. Laundry facilities designed to process 120,000 lbs. (57,606 kg) of laundry annually must meter and report all water use from the laundry operations.

Option 2. Leak Detection Sensors

Water lost through leaks strains capital and natural resources while creating health and safety risks. [86] Lower system pressures can draw pollutants in from the surroundings, leading to foul drinking water. [87] Capital losses can result from labor costs to identify the location of the leak and
