Conservation of City Water Cooling on Process Units to Chilled Water Loop
The component to change city water cooled equipment to campus chilled water loop has been completed for all campus facilities and cafeterias in 2014/2015. This retrofit ensures compliance with the current potable water use regulations with the benefit of the reduction in fresh potable water consumption. Results are presented in the table below.
Water System Retrofit in Life Sciences Building Fish Tank Room
The Building 39 Life Sciences Facility has a fish research room which currently utilizes potable water through fish tanks and drains it to the sewage system. The current annual consumption of city water is approximately 50,000 m3 or $ 140,000 in annual costs at current water rates. This is a significant potable water consumption area on campus.
The project involves implementing best practices from fish research labs at University of Guelph, Aqua Lab and Environment Canada and implement a filtration and circulation system which would have the capability to reduce potable water consumption by 80-95%. Preliminary engineering on the project has been completed and has been approved by the relevant faculty and lab staff.
Although urinals might not normally be an interesting topic of conversation, the ones in the David Braley Athletic Centre have a very unique aspect to them. They are ultra low-flush and only use 1/2 a litre of water per flush! Research done for the recently released Campus Sustainability Assessment Framework shows that older model toilets previously used on campus consumed up to 5.5 gallons of water per flush. This has been a major advancement in the preservation of municipal water and has also helped to decrease our dependence on the amount of potable water supplied to us.
