Conserving Water

Study Tip
Think of saving water as saving money. There is only a finite supply, so spending it sparingly can extend the time you have water (money) so you can spend it when you need to.

Why Conserve?

  • Water conservation is the reduction of water consumption. Saving water conserves energy, resources, and money.
  • Clean water supply is finite. Of all the Earth’s water 97% is undrinkable.
  • Saving water makes it more available for the future.

Impact on the Environment

  • The amount of water society uses can be reduced if financial incentives are given.
  • Avoid polluting water so that less is needed.
  • Use more efficient irrigation methods on farms and gardens.
  • Reduce household demand by installing water-saving devices such as low-flow showerheads.
  • Individuals can engage in many different water-saving practices.
