What is the baseline water use of a urinal?

The baseline water use of a urinal is defined as 1.0 gallons per flush (gpf). This standard has been established to provide a baseline for water efficiency measures in various settings, such as commercial buildings and institutions. This means that if a urinal uses 1.0 gpf, it meets the expected water consumption for conventional units at the time of setting this standard.

Choosing 1.0 gpf as the baseline is significant for calculating water savings when newer, more efficient plumbing fixtures are installed. Fixtures that consume less than this baseline significantly contribute to overall water efficiency goals, which are crucial for LEED certification and promoting sustainability.

The other options represent water consumption levels that may apply to different styles or types of urinals but do not reflect the baseline established for typical fixtures. Understanding this baseline is essential for anyone involved in designing, installing, or evaluating plumbing systems for LEED compliance.
