Linda Kogan, director, Office of Sustainability, provided toileting tips this week following the installation of dual flush valve-equipped toilets in several campus buildings. The toilets, recognizable by their green handles, allow users to move the handle up to dispose of liquid waste and down for solid material. The dual-valve equipped toilets are in women’s restrooms. Low-flush urinals are in place in men’s restrooms. The changes will reduce campus water use.
