A new water treatment program for the Toronto Western Hospital cooling towers – part of the chiller plant used to cool the hospital – has resulted in significant water reduction and lower costs.
The new program has resulted in reducing:
- Water use by more than 16,000 litres a year;
- Maintenance costs for the cooling towers by $18,000 per year.
Water treatment is used to prevent corrosion of equipment, build-up of scale and growth of bacteria, which can decrease the performance of equipment, cause serious damage and, for bacteria, lead to potential health concerns.
Collaboration between TW Facilities, Environmental Services and UHN Infrastructure helped launch the new program.
