Understanding the Value of Water

The Global Context

Globally, less than 3% of Earth’s water is freshwater, and only a fraction of that is easily accessible for human use. According to the United Nations, billions of people live in regions experiencing water stress, and projections suggest this number will continue to rise by 2030 if current consumption patterns persist. This scarcity is not limited to arid regions; even water-rich countries like Canada and Norway are implementing conservation strategies to ensure future security.

The Household Contribution

Residential water use may seem small in the face of industrial and agricultural consumption, but homes account for a significant share of local water demand, particularly in developed nations. In the United States, for instance, the Environmental Protection Agency (EPA) reports that the average household uses more than 300 gallons per day, with showers, toilets, and laundry leading the way. Simple changes—like upgrading fixtures, fixing leaks, and adopting mindful habits—can reduce this dramatically.

Practical Tips for Water Conservation Indoors
