Sustainable water policy

The calculation of the scenarios proceeded as follows: 1. The improvement from the business-as-usual scenario for each of the enhanced efficiency and water soft path scenarios in the Oliver case study were calculated as ratios. [...] The number of operations each day depends on the intensity of use of the ice rink, the sorts of activity (hockey being more destructive of an ice surface than recreational skating, for example), and the arena's budget. [...] Other efficiency and conservation opportunities to save on water use include: re-use water for outside irrigation or perhaps even within the arena (grey water use in toilets); purifying water before the building of the ice pad (pure water makes harder ice, allowing a thinner ice sheet and reducing the number of resurfacing treatments); temperature and humidity control of the arena volume are impor [...] The volatility in irrigation water used in this sector may reflect the decline in 1 The value of “Seasonal Irrigation” is based on summing the amounts of irrigation water used for all crops grown during the summer and excludes crops grown year-round using irrigation such as greenhouse products and mushrooms. [...] THE INDUSTRIAL SECTOR The national importance of industrial activity in Ontario is mirrored in industrial water use in the province.
