Which of the following does a facility operator need in order to optimize water consumption?

Submetering systems are devices that measure the water consumption of specific building components, such as cooling towers, irrigation systems, process water systems, or tenant spaces. They allow the facility operator to monitor and optimize the water use of different systems and identify any leaks or inefficiencies12. Submetering systems are also required for some LEED credits, such as Water Metering and Cooling Tower Water Use3.
