A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

ISU has taken the initiative of retrofitting leaking faucets within the academic buildings as well as upgrading water bottle filling stations to be more efficient.

ISU minimally utilizes water catchment for irrigation purposes. Grey water systems are not formally adopted in the Illinois Plumbing Code.


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

ISU regularly employs the installation of aerators in sinks, Water Sense plumbing fixtures, and has completed some retrofits to decrease sediment for the installation of water bottle filling stations.
