A brief description of when and why the water use baseline was adopted:

This is the baseline year adopted in the University Sustainability Plan. This figure assumes 80,000 m3 of water for the Agricultural campus in the baseline year. There is no historical measurement of water. As of FY 2018, the Campus is now connected to the Town of Truro's water supply, and thus accurate reporting in the performance year is being provided.

A brief description of the institution's water-related behavior change initiatives:

Water conservation is a key program area highlighted in ecolympics and through social marketing Rethink signage and messages. As well, significant fixture retrofits have been made such as low flow shower head, faucet aerators, dual flushing / low flow toilets, timed/occupancy driven urinal flush systems, etc.


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

There is a cistern to collect non-potable water in the Mona Campbell, LeMarchant Place, and Design buildings. Rain water cisterns will be added in new buildings. Also there have been retrofits of large research water units to recycle water (Aquatron).

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

Reducing water consumption - The University has completed many water efficiency projects such as adding sensors to older urinal tanks, installing low flow fixtures and toilets for new and existing buildings, adding rain water cisterns in new buildings, and retrofitting large research water units to recycle water (Aquatron). Upcoming projects are focusing on reducing water used for cooling equipment and air and in research.
