Increase employee awareness of water conservation. Install signs encouraging water conservation in employee and customer restrooms. Regularly check fixtures for leaks, especially faucets, toilets, showerheads, and urinals and repair them as soon as possible. Replace old fixtures with high-efficiency models. Review and compare water bills for indication of leakage or unexpected increases in usage. Take periodic water readings during periods when the building is not used to determine if background leakage or usage is occurring.
