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

In 2022, MRU upgraded its irrigation system. The new system that we are installing will provide us with all the information that is being asked in these forms, but it will be not be tested until the start of the new 2023 irrigation season. Once the system is installed up and running, we will have the ability to read our flow, gather how much water was used and where we use the most, read the existing moisture in the ground to allow us to water to our Manageable Allowable Depletion point, ensuring we don’t over or underwater based on weather events. This will ensure that any rainwater we get is registered in the soil and the system will not water. This smart irrigation system will also allow us to set up irrigation cycles in microclimates to allow weather based irrigation, reducing the areas that require irrigation and allowing us to focus on high traffic, high priority areas. Also, the systems pumps are not controlled by me, or the grounds department. Flow, pressure, pump readings, usage etc are all controlled by Building Operations. I have no access to that in formation so I can’t even begin to guess what was used, where, how many times the pond is filled, how much is drawn from the pond etc.

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

A rainwater harvesting system has been implemented at the Mount Royal University Roderick Mah Centre for Continuous Learning with the purpose of using undesired potable water for the flushing of toilets and urinals. The system consists of underground rainwater tanks, complete with a chlorine water treatment system and pumping system, which delivers stored and treated rainwater on demand to these functions within the building.

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

All LEED buildings have low flow fixtures and auto-flush valves.
