The WaterSense program primarily focuses on identifying and promoting water-efficient products. This initiative, established by the U.S. Environmental Protection Agency (EPA), aims to reduce water consumption while maintaining performance and savings for consumers. WaterSense-labeled products, such as faucets, toilets, and irrigation equipment, are rigorously tested and verified to ensure they meet specific efficiency criteria. By encouraging the use of these products, the program helps consumers make informed choices that contribute to water conservation efforts and lead to measurable environmental benefits.

The other options, while related to water or resource efficiency, do not accurately capture the main focus of the WaterSense program. The program does not directly address energy efficiency, plumbing code regulations, or the certification of building materials as its primary objective, which is why they do not align with the core purpose of WaterSense.
