A number of reports and studies have researched touchless faucets in public restrooms and commercial restrooms based on reasons including water conservation, sanitation, desire of the user, and performance of the service. Significant findings are:
Touchless Faucets In Public Restrooms
1. Water Conservation
California State University, Sacramento (2016):
There was a comparison study made between manual faucets and automatic faucets with 0.5 gpm and 0.35 gpm aerators. The result was that the automatic faucet with a 0.5 gpm aerator showed the saving of 32% water, and employing a 0.35 gpm aerator saved 54% water, which shows that touchless faucets are so much more water efficient.

Different Institutions:
Several case studies have reported remarkable water savings after touchless faucets had been installed. Denver International Airport, for example, experienced a 45% reduction in water use, and the University of Michigan recorded a 41% reduction, which reflects the water-saving effectiveness of sensor-activated faucets in areas of high traffic.

2. Hygiene Enhancement
Bacterial Contamination on Manual Faucets:
A 2015 American Journal of Infection Control study investigated bacterial contamination on various surfaces in public toilets, including faucet handles. The research found that faucet handles had more bacteria than other surfaces, which was an indicator of cross-contamination risk.

User Preferences After the Pandemic:
A post-pandemic American survey found that 82% of Americans consider touchless public bathroom fixtures important. Moreover, 50% of respondents reported feeling safer from germs when they used touch-free-equipped bathrooms, clearly indicating a preference for touchless fixtures to ensure cleanliness.

3. Operational Performance and Maintenance
Early Developments:
Automatic faucets began to be applied since the 1970s with the term "proximity faucets" as an effort to provide convenience, reduce maintenance, and increase hygiene. Over the years, advances in technology displaced initial shortcomings such that automatic faucets have become widespread throughout public facilities.

User Behavior and Maintenance:
User practice and maintenance will affect the performance of touchless faucets. Proper installation and upkeep are required to allow them to function and save water as efficiently as possible.

These studies collectively stress that touchless faucets installed in public and commercial toilets can result in considerable water savings, enhanced hygiene, and higher customer satisfaction. But the success of such installations hinges on the right selection of aerators, educating the users, and regular habits of maintenance.
