In 2017, the Region of Peel retained Enviro-Stewards to complete a water assessment at Trillium Health Partners’ Credit Valley Hospital under the Region’s Indoor Water Assessment program.
The hospital implemented two water efficiency measures:
- Sterilizer units using water eductors were replaced with new ones equipped with vacuum pumps.
- A heat exchanger was installed to preheat boiler feed-water using the boiler blowdown water, eliminating the need for blowdown cooling water.
These two measures together saved 18,615 cubic metres of water per year.
