Reducing water usage does more than lower your water bill. Saving water means that we use less water from rivers, bays, and estuaries — and this is a big deal for our environment. When we use less water, we also reduce water and wastewater treatment costs. Plus, it takes a lot of energy to treat, pump, and heat our water, all of which contribute to air pollution. In areas threatened by drought, reducing our personal water usage ensures our neighbors, friends, and family also have access to the water they need.
