A brief description of any water recovery and reuse systems employed by the institution:

A brief description of any water metering and management systems employed by the institution:

All water is sourced from the City of Spokane and is metered by them. The university uses a computer based irrigation control system to manage all irrigation.

Low flow showerheads, low flow aeroters on faucets and low-flow toilets where applicable.

A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:
A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):

Gonzaga University uses a limited amounts of drip irrigation. Low to no irrigation is used for native vegetation along the shoreline. Plants are selected to minimize waste by choosing species for purchase that are appropriate to the microclimate. Native and drought tolerant plants that require minimal or no watering once established should be purchased in accordance with the Campus Landscape Master Plan.

A brief description of any weather-informed irrigation technologies employed by the institution:

As part of an ongoing initiative, new computerized irrigation controllers were installed in the spring and summer (2010). These controllers allow staff to remotely monitor and control water outputs across campus based on weather patterns, thus greatly reducing water consumption.
