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:

The Office of Sustainability conducts a variety of outreach efforts through its student intern program and its employee Peers Network program. Typical yearly efforts tied to water conservation include social media messaging, No Impact Week activities, office strategy checklists, posters, and messaging shared through tabling at events around campus. The office also features water management information on its new employee education material and on its website for both Living at AU and Working at AU.


A brief description of the institution's water recovery and reuse initiatives:

One 500-gallon and 3 connected 55-gallon cisterns that harvest rainwater from a building roof are currently in place at the Davis Arboretum. The rainwater captured is used to refill the Little Cahaba exhibit or to water plants. In a bog at the arboretum are an underground 1400 gallon tank and a 1700 gallon above ground tank installed in early 2011. Both use water captured from the shed/outdoor classroom roof to operate the water feature and keep the bog hydrated. The underground tank has a pump that is powered by a solar panel; the above ground tank uses gravity. Other cisterns are installed at the AU Raptor Center, and the Architecture Shop Building.


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):

Current design standards call for high-efficiency faucets, low-flow showerheads, and where feasible, high-efficiency toilets/urinals.
