Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Total water use (potable and non-potable combined):
| Performance Year | Baseline Year | |
| Total water use | 245,794 Cubic meters | 229,419 Cubic meters |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 245,794 Cubic meters | 229,419 Cubic meters |
Start and end dates of the performance year and baseline year (or three-year periods):
| Start Date | End Date | |
| Performance Year | Jan. 1, 2017 | Dec. 31, 2017 |
| Baseline Year | Jan. 1, 2015 | Dec. 31, 2015 |
A brief description of when and why the water use baseline was adopted:
The water baseline was adopted for this STARS report. 2015 was selected at the baseline year as we have recent complete data for that year and we can see the change that has happening recently.
Figures needed to determine "Weighted Campus Users":
| Performance Year | Baseline Year | |
| Number of students resident on-site | 3,857 | 1,933 |
| Number of employees resident on-site | 12 | |
| Number of other individuals resident on-site and/or staffed hospital beds | ||
| Total full-time equivalent student enrollment | 16,373 | 14,767 |
| Full-time equivalent of employees (staff + faculty) | 1,970.82 | 1,986 |
| Full-time equivalent of students enrolled exclusively in distance education | 961 | 740 |
| Weighted campus users |
Potable water use per weighted campus user:
| Performance Year | Baseline Year | |
| Potable water use per weighted campus user | 4,636.55 Cubic meters | 4,851.20 Cubic meters |
Percentage reduction in potable water use per weighted campus user from baseline:
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area | 380,382.37 Gross square meters | 212,981.89 Gross square meters |
Potable water use per unit of floor area:
| Performance Year | Baseline Year | |
| Potable water use per unit of floor area | 15.86 Cubic meters per square meter | 26.44 Cubic meters per square meter |
Percentage reduction in potable water use per unit of floor area from baseline:
Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):
Area of vegetated grounds:
| Performance Year | Baseline Year | |
| Vegetated grounds | 4.05 Hectares | 6.07 Hectares |
Total water use (potable + non-potable) per unit of vegetated grounds:
| Performance Year | Baseline Year | |
| Total water use per unit of vegetated grounds | 6,493,190.53 Cubic meters per hectare | 4,040,405.87 Cubic meters per hectare |
Percentage reduction in total water use per unit of vegetated grounds from baseline:
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:
Water Filling Stations: When new students arrive at Laurier’s Waterloo and Brantford campuses in September, refillable water bottles are included in their welcome package. The goal is to discourage students from quenching their thirst with water in one-time-use plastic bottles. Bottled water can no longer be purchased in vending machines or at food outlets at Laurier campuses in both Brantford and Waterloo. Instead, students are encouraged to bring their reusable bottles to 22 water fill-up stations, set up in high-traffic areas of the campuses. These new models feature a digital counter which tracks the number of plastic water bottles each fountain has helped to avoid.
A brief description of the institution's water recovery and reuse initiatives:
In our newly constructed LEED Gold building, Lazaridis Hall, a grey water system collects and filters rainwater for use in toilets and landscaping.
Laurier uses a 37,000 litre rain water harvesting system to water plant material on campus and has also recently installed a 2350 litre system that is also used for irrigation.
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):
Also included in the LEEP Phase 1 & 2 projects was a retrofit of water fixtures in 32 buildings. The buildings are a mix of residential, administration, academic, athletic, and dining each with a large demand for water. Tank and flush valve toilets were replaced with 3.0 and 4.2 liter low flow type in all locations where 6.0 liter or greater were existing. Aerators and shower heads were also installed in all locations.
