1) As water shortages become more widespread due to droughts, population growth, etc., new technologies for water conservation are needed.

2) Finite Faucet is a new design for a water-saving public restroom faucet installation.
- Based on CDC guidelines for handwashing that only require two short bursts of water – once to wet your hands, and once again to rinse off the soap
- The Finite Faucet is made almost exclusively of reclaimed metals, plastics, and parts, and can be fully recycled again at end of lifespan
- When you turn on the Finite Faucet, it drains until it is empty, and must be turned off to refill
- Upper cylinder acts as a visual reminder of water usage
- Refilling water acts as timer for scrubbing your hands (20 seconds)
3) Organizational stakeholders: facilities managers in corporate offices, airports and other transportation facilities, etc.
4) Steps to deploy:
- Contact management at airports scheduled for renovation, to include Finite Faucet as part of the project
- Estimate costs and develop plan to retrofit restrooms in office buildings
- Identify corporate partners for pilot projects in office buildings

This is a great passive way to encourage behavioral change to use less water. However, I do see an issue in restrooms that experience high volume – the additional time it takes to refill the water after your rinse your hands would queue a line. I would include an additional step to conduct an occupant simulation to determine the number of faucets necessary in high-volume areas.

Faucet promotes proper hand-washing, uses just 12% of the water used in an average faucet, is made of 85% recycled material and is 93.5% recyclable.
