A brief description of the institution's water-related behavior change initiatives:
Humber has invested in retrofitting existing water fountains with sensor activated water bottle refilling stations. The stations are also included in new construction. The new fountains allow students and staff to have easy access to safe, clean drinking water and reduces the amount of waste from plastic water bottles.
A brief description of the institution's water recovery and reuse initiatives:
Humber's greenhouse has two large rainwater collection tanks and the Centre for Urban Ecology building has a 10,000 litre cistern. Rainwater collected is used for greenhouse operations and surrounding gardens.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
Examples of water efficiency projects at Humber College:
• replaced 17, 6LPF toilets with 3LPF water-efficient models in one student Residence building
• upgraded existing 2.5 gpm flowrate showerheads to 1.5 gpm in one student Residence building
• replaced water-cooled equipment with DX units
• replaced 17, 6LPF toilets with 3LPF water-efficient models in one student Residence building
• upgraded existing 2.5 gpm flowrate showerheads to 1.5 gpm in one student Residence building
• replaced water-cooled equipment with DX units

Data source(s) and notes about the submission:
It seems that the vegetated grounds information for 2016 included the Humber Arboretum, which is actually not part of Humber, hence it was a mistake. The vegetated grounds # was recalculated for this year, and the baseline year was updated.
