operators and tenants, the approach for resolving detected leaks, and a communication plan to alert building occupants when repairs impact the building.

Flush fixture leak detection requirements For the flush fixtures, install sensors or meters for at least 50% of the flush fixtures identified in WEp1: Minimum Water Efficiency .
