What is the maximum delivery of water per metering cycle required for lavatory faucets in public toilet facilities according to the text?

1. 1 G.P.M.

2. 0.25 G.P.M.

3. 2 G.P.M.

4. 0.5 G.P.M.

The correct answer is: 0.25 G.P.M.

The maximum delivery of water per metering cycle required for lavatory faucets in public toilet facilities is specified as 0.25 gallons per minute (G.P.M.). This figure is established to ensure water conservation while still providing adequate service to users. Setting a limit of 0.25 G.P.M. aligns with efforts to reduce water waste in public restrooms, reflecting both environmental considerations and the need for efficiency in fixtures. Such standards help regulate water usage to ensure that lavatory faucets do not overpower water supply systems, which can lead to excessive consumption and increased costs, particularly in public facilities that experience high turnover. Other options present different flow rates that exceed the specified maximum, which would not only contravene regulations but also negate the intent behind water-saving fixtures in public spaces. Thus, the emphasis is on minimizing water delivery to foster sustainability without compromising user needs.
