BC Place stadium in Vancouver, BC implemented a rainwater harvesting system on the 11 acre roof that collects and stores rainwater for use in cleaning, toilets, field irrigation and other non-potable uses. They estimate it saves 950,000L of drinking water per year. https://www.bcplace.com/blog/2021-04-22/how-bc-place-is-buil...
How much pristine drinking water does BC Place use in a year (an important fact missing from the article)? If the answer is 2.5 million liters then I’m amazed. If the answer is 25 million liters, I’m much less impressed.
I feel like that is an absurdly low amount for a person to drink per year.
Also, I don't think the 100 gallon number includes industrial use like "golf courses".
> The average American family uses more than 300 gallons of water per day at home. Roughly 70 percent of this use occurs indoors. In addition, there are other miscellaneous uses of water in the house which may be very significant, depending on the degree of water conservation by the household.
